Jokes aside, the cost of buying brand new tires can be a pain. Especially if you own a sports car, pick-up truck, or an off-road/SUV equipped with with a 20 plus inch tire. For example, those tires can cost north of $400 for Yokohama Geolandar X-AT a piece! A quick calculation will bring you to a total of $1600 for all 4. What about used tires? How much do those cost?
How Much Do Used Tires Sell For?Well depending on various conditions, like the tire tread wear, it can be as far as 40-60% of the price of the new tire. The logic behind that should be 40% tire tread wear, 40% of the price of a new tire, but it also depends on the dimensions and e t.c. So, it is actually a fair amount of money that you can save on buying used tires. Easy-peasy? Not quite. You should do some research in order to avoid any traps and be better prepared to choose the right tire.
What to look for while choosing used tiresWell, obviously you should check for any visual damage as, after all, we are talking about a tire that was used, probably, every day. Beware of any chips and damages sustained from parking a car by the sidewalks, for instance. Another reason for worrying is damage that can appear while running over a pothole, especially the ones that are not properly leveled and have nasty sharp edges. The cut damage from hitting a pothole or a sidewalk is one thing but a bulge can also be dangerous as it disrupts the integrity of the tire and can potentially lead to a flat tire with an explosive bang effect. Highly dangerous!
And after all, any damage can be acceptable if the repair is done right by the professionals. Any honest repair shop will do this as it should be done and any patch or tire plug shouldn’t be a thing to be worried about. If the tire patch is made to the sidewall, tire tread shoulder, or belt edge, then you should avoid these used tires and that used tire shop altogether. That is not a safe tire.
Retreaded tireWhen the tires are worn enough to become unusable, there is the option to be retreaded.
That means that a new layer of rubber tread is laid down in order to make the tire usable again. The biggest benefit here, besides the lower price compared to buying a new tire, is one less used tire thrown away. This means that there is no need for another waste of energy in order to recycle a tire, or even worse for the tire to be just laying around and piling in someone’s backyard.
While there are a lot of companies that are using this technology to “bring back the life” to the tire, there is also a good reason why big manufacturers are not retreading their tires. Should you avoid a retreaded tire? It is up to you. There is a possibility of the retreaded tire delaminate which can lead to the obvious dangerous situation. The smartest thing to do is to check the retreading company’s background and see if the customers have some complaints about any problems.
Tire ageThe tire age is one of the most important indicators, besides the tire tread wear that you should consider when buying a used tire.
A general opinion is that a tire can be used up to 10 years, but be aware as the older it gets it loses the ability to maintain good contact to the road due to the loss of elastic characteristic of the tire. That is why car manufacturers recommend changing a tire at a maximum of 6 years in which period a tire can still retain its optimal characteristics.
How can you determine the tire age? There is a four-digit DOT code on the sidewall of the tire that shows us the week and the year in which the tire was manufactured. For example DOT code 1017 shows that the tire was manufactured in the 10th week of the year 2017.
Tire treadThe tire tread wear can be easily measured if the tire was properly used and evenly worn. If there is an anomaly that indicates uneven wear of the tire, don’t buy it! Uneven tire wear shows that either the driver wasn’t very gentle with the vehicle hence the tires, or that his vehicle wasn’t technically OK, or the tires weren’t aligned properly.
Those tires won’t do any good to your car, buddy.
The easiest and the most usual test for measuring the tire tread depth is by using a penny coin.
Just insert the penny into the tire grooves, with the head of the famous president upside down, and check if the head is covered by the tread or not. If the tip of the head is covered then the tire tread is at least 2/32 inches, which is just enough. Repeat this test on various parts of the tire tread to be sure that it is evenly worn. Anyway, this is the bare minimum and you should avoid this tire as it will be a bad investment unless you are selling your car and don’t want to invest much.
If you are buying used tires and still want to be safe and sound, then you should know that tire tread is directly related to performance. Of course, the tire compound is the biggest factor, but the tire tread can affect the performance, especially the stopping distance while braking. For example, a new tire with 10/32nds tread can be almost double more efficient under braking than a heavily used tire with 2/32nds tread.
Safety is most important and you should have this information on your mind when choosing a used tire.
If you are driving on snow this is even more important.
OriginWhy is that important? Well, up north, on the snowy roads, the tires could be potentially exposed to salt which can damage them if not used properly or washed after driving on a road paved with that raw salt. On the other hand, if the tires were used down there on scorching Tennessee sun, then there is a good chance that no matter how “young” the tires are, they are probably unusable as they’ve lost all the flexibility and can deteriorate sooner than usual.
So the origin of the used tire is a very important factor but is also very difficult to detect especially if you are not buying them from the owner on ads, rather from a shop that can’t guarantee that information.
ConclusionIf you are expecting to get a straight answer if you should go ahead with buying a used tire instead of a new one, well, that is up to you and your personal estimation.
Whether you need to change your tires because the lease is coming to the end or you are looking to sell your car, or you need to change your tires because yours are finished, used tires are a great option. You’ll save a lot of money, which in these pandemic times can make a difference, and you’ll also be able to choose a tire model that was maybe unreachable when new.
Yours truly had an unpleasant experience with used tires that had sufficient tire tread but they were old enough to perform like driving on ice. The other bad news is that those tires were fitted on a 2008 Yamaha FZ6 and I had 2 months of riding experience at the time. So of course I fell off the motorcycle because I wasn’t able to stop when needed. The good thing was that I arrived in the middle of the corner riding at 20 mph so the fall wasn’t very heavy, but the bad thing was that I took my wife with me on that ride. So my wife’s broken palm as a result of all that and a very expensive lection about research for used tires.
My point is that the tires are the only thing that keeps you safe on the road so you have to be thorough when researching for used tires and you’ll be just fine. Don’t be naïve and use all the knowledge that you’ve learned in this article and go out there playing detective. Buying used tires doesn’t have to be a boring thing especially if you know a trick or two about it!
Those who don’t have enough money to purchase new tires or insurance to cover tire replacement have no choice but to purchase second-hand tires.
However, used tires may still have sufficient tread depth and be free from unusual and uneven tread wear. But how much do these tires cost? If you’d like to find out, keep reading!
Used tires range in price from $25 to $160 with a complete set selling at $100 to $650, or 30% to 50% less than a new tire of the same type. A set of four tires is priced between $224 and $325 on Craigslist and Facebook MarketPlace.
Therefore, used tires are a viable option if you’re seeking to save money.
To learn more about used tire pricing, if you should consider buying used tires, how to choose the best used tires and more, keep reading for more facts!
How Much Should 4 Used Tires Cost?You could pay between $25 to $160 for a single used tire, meaning a whole set may sell at $100 to $650, or 30% to 50% lower than a new tire of a similar model.
This figure is dependent on a variety of factors, such as tire size or if they come mounted on a wheel or not. Therefore, you might pay $50 or $90 for the same kind of tire.
Tires with low mileage are obviously more valuable than tires that are virtually worn out, and the price of a large truck tire is generally more than the price of a typical passenger car tire.
Additionally, because of their higher original price and residual value, low profile and performance tires will likewise command a premium.
Not all brands and models have a long wear life, as some treads last longer than others, and tread life is sometimes dictated by the kind of tire.
Touring tires, for example, are supposed to last longer than performance or summer tires.
This may also be true of H/T or highway-terrain tires, which have a longer wear life than A/T or all-terrain tires for pickup trucks or SUVs.
In most situations, tread life is determined by a variety of factors, including the vehicle’s overall condition, driving habits, miles traveled, and present road/weather conditions. Therefore, the life expectancy of your tires depends on how and where you drive your car.
Although you may not be able to manage the latter, if you drive carefully and responsibly, you should be able to fully maximize a pair of used tires.
How Do I Choose A Good Set Of Used Tires?Experienced drivers wouldn’t recommend buying anything unless the tread depth is at least 7 to 9/32″ -, or even higher if it’s a more aggressive truck or SUV tire.
Anything less is bad when traction, comfort, and durability are taken into consideration.
Therefore, wherever you shop, double-check the listings. Most vendors outright display the remaining tread depth, but you should take this with a grain of salt.
For safety, actual product photographs should be included in the listings. If you see anything unusual (such as bald areas or uneven wear marks), move on and look for alternative options.
Does Walmart Sell Used Tires?Walmart doesn’t sell or install old tires since it only sells items with UPC numbers.
Therefore, if you’re seeking second-hand tires, go to Facebook MarketPlace or Craigslist, where you could get single tires for $89-$103 or a set of four for $224-$325.
A single used tire costs an average of $25-$160, which is comparable to Walmart’s new tires, which cost an average of $31-$102.
Is It Okay To Purchase Used Tires?You should only put used tires on your car if they are really necessary, because since used tires aren’t regulated, there’s no way of knowing if they’re safe.
Tread degradation can easily be observed, but internal tire deterioration is difficult to spot unless you’re a specialist.
If you’re in need of tires, it’s strongly advised to purchase new ones from a reputable shop rather than buying used tires from a vendor.
Purchasing a used tire to be used as a spare isn’t as bad. However, to keep your car safe, never buy a whole set of secondhand tires.
How Can You Tell If A Used Tire Is Good?Before purchasing used tires, make sure you check out factors such as tread depth, tread and sidewall condition, repairs, and age.
A regular new tire has a tread depth of 10/32 to 11/32 of an inch, while 2/32 of an inch is the legal minimum tread.
At least 5-6/32 of the tread depth on a decent used tire should be left, which can be determined by using the penny test.
If a significant portion of the head side of the penny is visible, it will be fair to assume that the tread is around 2/32 inches and thus in violation of safety measures.
If a used tire’s tread depth appears to be adequate, inspect the whole surface of the tire for noticeable cracks or cuts in the sidewall. It’s also hazardous to use if the sidewall has bumps or other irregularities, as an impact might cause the rubber to delaminate from the belting.
Therefore, look for traces of repair on the interior of the tire (it must have been repaired with a tire plug if you see crude nubs of rubber sticking up).
Tires now have a four-digit number on them that identifies their age; the first two numerals indicate the week in which it was manufactured, while the final two digits indicate the year.
A tire with the DOT number 1208, for example, was manufactured in the 12th week of 2008.
Tires that are more than 6 years old should be avoided since the oil in the rubber begins to dry up with time, resulting in dry rot, cracking, and a hazardous tire.
To learn more about tires, you can also see our posts if you can sell used tires, if you can buy used tires, where you can dispose of tires for free, and how tires are recycled.
While it’s not suggested that old rubber is always better than new, the cost savings potential is undeniable for purchasing used tires instead of new. Therefore, as long as used tires pass inspection and have sufficient tread left, they are safe.
If you’re considering buying used tires for your car, make sure you buy from a reputable vendor, which guarantees that each tire will be extensively tested and certified for the road.

The motorist's budget is hit the hardest when you have to buy both summer and winter sets of tires within one year.
For example, the popular Nissan Qashqai is equipped with 225/45 R19 tires in the maximum configuration, a set of the middle price category will cost about 50,000 RUR.
But there is an option to save money and buy used tires. This article will tell you how to safely buy used tires and when you shouldn't.

Or the season has changed. We wrote in detail about how to assess the condition of tires and understand when they need to be changed in a separate instruction. Before you start looking for tires, it is important to be able to read their parameters. The most important in this situation are the size, manufacturer and model of the tire. nine0003
If the task is to buy a set of four tires, then it is important to respect the size. If you damaged one tire, you will have to look for exactly the same one: two wheels of the same axle must have tires with the same tread pattern, and this is possible only in the case of tires of the same model.

How to save money on buying car tires and wheels?
Tire parameters important to look for: width, profile height and rim diameter Tire manufacturer and modelAccording to Avtostat, an average car in Russia drives 17,500 km per year. Let's take the average wear resistance of tires according to the Treadwear index - 320 and calculate how long a new set of summer tires could theoretically last.
Every 100 index units is 12,500 km, which means tires are rated for 40,000 km. Assuming that the summer kit is used for 6 months out of 12, the mileage for six months is 8750 km, and the kit is enough for 4.5 seasons.
If the annual mileage is 30,000 km, then the summer kit should wear out in 2.7 seasons. But I have not met people who change tires in the middle of the season: either they change them in the spring, or they drive them until autumn. nine0003
Judging by Yandex Market, the average popular tire 205/55 R16 costs 5500 R, which means that the set is 22 000 R.
Let's round up 2.7 to three full seasons. One season costs Rs. pay more than 14,000 R. How to evaluate the tread depth on a used tire, we will tell a little later. nine0003

Or it will help those who know for sure that at the end of the season they will change the car: there is no point in buying new tires for the next driver. However, the theoretical calculation does not take into account your travel time for the next purchase and the risks of buying a bad kit.

At first glance, selling tires is illogical. Tires need to be worn out completely and then disposed of, but the market for used rubber is huge. It has several types of sellers with very different offers. nine0003
Companies that sell used tires from Europe and Japan. Despite the ban on the import of used rubber, which has been in effect in the Eurasian Customs Union since January 1, 2010, this business is booming. The main thing is to prove that tires are not hazardous waste and they are not imported for recycling. Therefore, on Avito and various sites, many offices offer used tires of various brands, sizes and models.
| Benefits | Defects |
|---|---|
| Huge selection of summer tires Advice available, professionals know their product Usually there is a tire service on site Safer online shopping. Tire warranty until the first tire fitting, a defective tire will be changed to a good one or money will be returned | nine0081 There is almost no choice of winter tires: no studded and little friction - Velcro. You can only buy "euro-winter" for mild climatic conditions.
Here are some of the advantages of specialized stores that sell used tires:
But there are also disadvantages:
Dealers and tire shops. They differ from the first ones in scale - they are much smaller, and also in that they trade at best on the scale of one city. Often the base for such activities is a tire shop. They buy cheaply at Avito or from tire fitting clients, sell more expensively at Avito or other tire fitting clients. nine0003
There are also not very pleasant scenarios: an unscrupulous tire fitting worker offers to dispose of a completely normal set of tires “out of friendship” and gets it for free.
For another client, the same kit “very much nothing, two seasons will definitely pass” costs 15,000 rubles.

Individuals who sell unwanted tires for a variety of reasons. Here are the main ones:
Unfortunately, Avito is inundated with such announcements. nine0016 | Advantages of | Defects |
|---|---|
| You can search for tires by car make and model, not just size With a little luck, you can make a super bargain | It will take a long time and carefully to choose among ads Many do not know what they are selling (mistakes in tire names, sizes and models are normal) A rare seller agrees to tire fitting in his presence, everything will have to be checked by himself and by hand Many scammers: they can offer to leave an advance payment and disappear or send an erased kit instead of what is in the ad No warranty on tires |
Here are some of the benefits of buying used tires from individuals:
But there are also disadvantages:
Universal ad platforms: Avito, Yula and others.
Here is the largest selection of used tires. Both private traders and professionals sell. Despite the convenient application and filters, it takes a lot of time to search. Don't expect every seller to list the model correctly. Bridgestone Potenza can become just "Bridge Stone" - and this is not the worst option. nine0003
You will have to scroll through a huge number of ads with completely worn-out tires that are only suitable for recycling. Unfortunately, no filters will save you from this. Looking for tires on Avito is like looking for a treasure: you have to dig a lot, and no one guarantees a reward, but some are lucky.

Adjust the filter by size - so you will have more chances to find the tires you need You can no longer drive on such tires: they are worn out to the limit marks, this can be seen even in the photo. Plus, the sidewalls are very worn out. But the seller still thinks that he can get 3000 R for them Websites for car sales announcements: "Avto-ru" and "Drom".
There are few private ads here, mainly specialized stores operate on such sites.
Droma has the largest selection of used wheels and tires from Japan in the country. Drome offers a good customer protection service and acts as a guarantor of purchase: if they send you worn or damaged tires, the site will return the money. If everything is fine, they will be transferred to the seller.
At the time of writing the article on Avto-ru, there were only five private ads for the sale of tires of the common size 205/50 R17 throughout Russia. It makes no sense to look for tires from private traders on this site. Source: Avto-ruCar club sites: forums, chats, Drive-2 — places where representatives of car clubs communicate. Sometimes it can be difficult to find the site itself. This can be a group on Vkontakte, a chat on Telegram or WhatsApp.
There are fewer offers here, but they are more interesting, more likely to find a good set. It is not customary to post completely junk for sale in communities or to greatly inflate the price: the ad will be discussed, criticized, or even deleted altogether.
But don't forget about safety. You should not buy something without verification or send the entire amount to a stranger in another city. It is usually customary to ask a friend of a teammate to go look at the kit and make sure that the tires are sent. Here, as a rule, you can place your ad on the purchase of the necessary tires and wait for responses. nine0003
There is a flea market on Drive-2. It is not very popular, but it is worth looking into it: there are filters separately for disks, wheels and tires, you can specify the dimensions.

Special online stores and car disassembly. In most cases, such sellers open an official representative office on Avito, but some sites are still working. They may have rare tires or a more interesting price. Large auto-dismantlers rarely sell tires - they mainly sell sets of wheels. The condition of the tires on the rims is most often mediocre: a car is not sent to scrap on good tires.

Tire shops and car services. It's hard to find interesting deals on tires here, it's not their business. Tires in a tire shop are usually bought in emergency cases: when one or more tires are damaged, but you need to somehow drive a couple of weeks to pay.
Price. Before buying used tires, it is better to check the price of new tires of the right size. Tires from young Chinese brands are very cheap, and the market for used tires is overheated and overpriced. It is impossible to unequivocally answer which is better: a new tire from an unknown manufacturer or a used tire from a well-known brand. But it is necessary to compare, study reviews and weigh everything. nine0003 At first glance, an excellent offer. A set of fresh tires 215/55 R17 with 20% wear for 18,000 R. But the indicated balance of 6 mm is about 30% wear. The remaining tread of the new tire is 8 mm, the tread limiter bar has a height of 1.
6 mm. The tire is worn 2 mm. Usable tread depth: 8 mm − 1.6 mm = 6.4 mm. 2mm from 6.4mm is 31% wear. Source: Avito But then it turns out that the new ones are very inexpensive. The remaining 6 mm is two-thirds of the tire resource, which means that buying such a kit costs no more than 16,000 R. Source: Yandex Market
Manufacturer, model, size, indices and other features. Be sure to check all tire specifications - everything that is indicated on the sidewall. The seller may not understand tires well or deliberately lie. Carefully inspect each tire. For example, you can accidentally buy a set of four tires, where three will be with runflat technology and one without it. If buying tires remotely, always ask for individual photos of each tire in full detail, or even better, a video.
Tire year. Among the advertisements of specialized stores, there are often tires that are more than 5 years old. Tires may have excellent tread residue, but it is better to refrain from such a purchase.
The older the tire, the worse its properties and the greater the chance of hidden damage: cracks, delaminations and ruptures.

It is not necessary to measure the residual depth "by eye", it is better to buy a special device or use a caliper. The standard tread depth of new summer car tires is 7-8 mm, winter tires are 8-10 mm.

Do not buy tires with uneven tread wear. They will not be able to provide a complete drainage of water from the contact patch with the road, it is unsafe to ride on them. Severe cuts or even the absence of individual tread fragments will also be a reason to refuse a purchase. Without a specialist, you run the risk of buying a tire that you cannot use.
But do not be afraid of well-repaired punctures. Tires with patches on the inside of the tread part can be bought, this will not affect further operation. You should not buy tires on which punctures were repaired with a tourniquet. nine0003

Obviously, this tire is no good: there is almost no tread, the studs are completely worn out. The central part is almost completely missing, and the sidewalls are less worn. Maybe the tire was pumped. Surprisingly, they also sell such Cracks and delaminations.
Long longitudinal cracks, along the circumference of the tire on the sidewall or small cracks in the tread area - in any case, bad. Either such a tire was poorly stored, or it is very old. This is a particularly dangerous case, because such a tire can collapse while driving and cause a terrible accident. Cracks are not repaired, so you will have to refrain from buying. nine0003
Sidewall condition, damage and repairs. Hernias of any size, side cuts and patches on the side of the tire are good reasons to keep looking. You can't buy these tires.
Carefully inspect and feel the sidewalls of the tires. Unfortunately, not all defects can be found on a tire without a disk and without air inside. It will be ideal if you can mount tires on rims in a tire shop. Ask to balance the wheels and only then pay.

How to choose tires for a car or crossover
If in doubt that the tires are intact, look for another option.
Remember that it is the tires that connect your car and the road.
Presence of spikes and their condition. It is not necessary to count every stud on a tire, it is difficult and time consuming. Just look at the tire: if it seems that there are about half of the studs on it or less, you do not need to buy a tire. Studded tires without studs won't get Velcro, so don't just look at the tread.
Studs on a tire that has already been driven for a couple of seasons look very different from new ones. They were worn off along the way, the seats were broken. In the background, you can see that the tire has already begun to lose studs. Even with sufficient tread, you can be left without spikes very quickly, it is better to look for another option Ads often offer used tires at an inflated price.
We have made a special calculator that will help you calculate the fair value of tires, regardless of the manufacturer, technical parameters of tires and their number in the kit.

Critical tire wear: when we risk crossing the line
As you know, rubber loses its properties over time. It becomes less elastic, microcracks appear on its surface. Rubber, in the words of the drivers, "dube". The sidewalls become rigid, tire fitting is difficult. At the same time, the grip properties of the tire deteriorate, especially its ability to keep the car on wet pavement.
Tire age limit varies depending on the quality of the rubber compound and manufacturing technology.
According to GOST, the warranty period for tires is five years, and the further possibility of using the tire is determined by the consumer. As a rule, tires run longer depending on the mileage and the driver's accuracy. But you should think about buying tires older than eight years, even if they look decent and, without running a single kilometer, lay in the warehouse. nine0003
The production date is applied to the sidewall as a set of four digits: the first two are the week of manufacture, the next two are the year of manufacture. It is easy to calculate that, for example, the numbers "5012" mean that you have a tire released in December 2012.
The production date is printed on the sidewall as a set of four digits: the first two are the week of manufacture, the next two are the year of manufacture. It is easy to calculate that, for example, the numbers "5012" mean that you have a tire released in December 2012. nine0003
When buying a set, it is also important to choose not only tires of the same brand and model for all wheels, but also preferably ones that are close in age.
This is the only way to count on the fact that the purchased tires in terms of properties will not differ much from one another.
This is a special item when choosing a used tire. They can be divided into two groups - visible and hidden.
Visible include punctures, tears, cuts, hidden - damage to the cord. This kind of damage is clearly visible when examining the inside of the tire. You can allow the presence of "fungi" and patches from the side of the tread. But their number should not be excessive. The more patches, the more difficult it is to balance the wheels, and this affects the comfort and suspension parts while driving, and the residual life of the tire itself is reduced. nine0003

7 rubber signals: what the tire says about car problems
In addition, you need to remember that the patch blocks the exit of air from inside the wheel, but does not block the entry of moisture into the tire structure from the outside.
Water, including salt containing water, getting on the metal cord, first causes rust, and then the destruction of metal threads. In comparison with a patch, a sealing puncture on both sides (“fungus”) looks preferable. But patches on the sidewall are generally unacceptable. A tire with a side cut is unusable. In the best case, on a tire with a "healed" sidewall, you can, with care, get to the house, and then change the wheel. nine0003
It has been noticed that other sellers, in order to hide the patches and "medical history" of the tire, offer them complete with a disk. The buyer will not disassemble the wheel to inspect it from the inside! Often, the pressure in the tire is noticeably lower than the working one. The fact is that under normal pressure, internal damage can give itself away. Hence the advice: if you are looking at used tires, it is better to buy them without rims or not on rims.
A wheel inflated to working pressure must be smooth, have a clear geometric shape without hernias and swellings.
You can check this only by mounting the wheel on the disk and pumping it up. Therefore, when buying a used tire, it is necessary to discuss with the seller the possibility of a return in case of hidden defects. nine0003

7 main principles for choosing summer tires
In general, such defects are caused by damage to the cord after punctures or strong impacts. Outwardly, this manifests itself in the wave-like bends of the tread - the whole thing. This can either be noticed in the parking lot or felt when driving at a slow speed. A car with damaged tires starts rocking from side to side. With an increase in speed, "waltz" disappears, but the car loses stability. This is dangerous. nine0003
When the cord is peeled, hernias occur. Most often they are found in the shoulder area and are the result of a collision with a curbstone. How long a wheel with a hernia lasts, no one will undertake to predict.
This is the main criterion when choosing tires with mileage.
The tread depth determines how long you can drive on these tires. Remember that according to the Rules of the Road, the tread depth of summer car tires should not be less than 1.6 mm, and winter tires - less than 4 mm. It is clear that these indicators are critical, which means that a margin of no less than 2–3 mm must be added to them. nine0003
You also need to pay attention to the uniformity of tread wear. It should be the same in depth both in the center and along the side tracks around the entire circumference. In order for the wear pattern to be correct, measurements of the tread depth are carried out crosswise in diametrically opposite directions.
Buying used tires is a risky business. Too many pitfalls. It is one thing to buy tires from a neighbor or relative you trust, and quite another to buy a pig in a poke in the market.
