In older cars, every model came with a spare tire that matched the tires already on the vehicle. Over the years, car manufacturers have realized the spare tire is used so infrequently, it does not make much sense to equip every car with a full-sized spare. For this reason, manufacturers began leaving a space-saver spare (otherwise known as a donut) in place of a full-size spare.
Nowadays, spare tires should never be a permanent replacement, begging the question, how long can you really drive on a spare tire? The type of spare tire in your vehicle makes a difference in how long and how far you can drive before fixing your tire or buying a new tire.
These narrow, compact spares are designed to save space and weight in the vehicle, allowing the manufacturers to build a smaller car. However, the tire itself is not built to last. Your owner’s manual will give recommendations for driving time and speed. A general rule of thumb is to drive no farther than 70 miles and no faster than 50 miles per hour before replacing your donut with a new tire.
The biggest reason why you should avoid prolonged use of space-saver or donut tires is that they have little to no tread, making the spare vulnerable to road hazards and projectiles. It is also much smaller than the other 3 tires, making it spin faster to keep up with the moving car.
Run-flat tires are becoming more common as manufacturers realize they cost less to maintain than traditional tires. If you drive a recent model BMW or a MINI, your car likely came with run-flat tires. These tires are tougher than most tires but are not designed to last forever, such as a full-spare tire.
Rather than including a spare tire, these run-flat tires are built to withstand most road hazards, including punctures.
Rather than going flat or blowing out (as traditional tires do), a run-flat tire can continue to drive after punctured for about 50 miles before needing to be replaced
. However, these tires cost more to replace than traditional tires.
While you have a bit more room to travel on these types of tires, it is important to inspect your tire as soon as you are aware of any change in tire pressure. This gives you an idea of how long you have until you have no choice but to have your tire replaced.
How Long Can You Drive on a Full-Size Spare Tire?
For years, cars were built with spare tire wells capable of carrying a full-size spare. On many older cars (and a few newer models), this is still the case. If you bought a truck, SUV, or another large vehicle, your car probably is equipped with a full-size spare. While a full-size spare is heavier and requires a larger space for storage, these tires are more durable and can handle a drive similar to a regular tire.
Once you have taken your vehicle to an auto repair shop and learned that the punctured tire is irreparable, you can request the spare tire to be put on the original rim.It is important to note that a full-size spare tire is usually not produced by the same manufacturer as the rest of the tires on your vehicle, meaning it will handle differently than the other tires. We suggest buying a new tire as soon as you can afford to, but this can easily buy you some time.

If you have a flat tire, you know how frustrating a process it is to get your car back to its normal operation. Not only does it disrupt your travel, it also takes time and money to replace a flat. After you change the flat tire and install your spare, you might be wondering: how long can you drive on it?
In this article, we’ll tell you just how far you can drive on a spare tire, what the key differences in types of spare tires are, and best practices for driving on a spare tire.
Let’s jump right in by answering your main question:
You should drive no more than 50 miles on a temporary or donut spare tire if possible. If you absolutely must go longer than 50 miles, avoid driving on it longer than 70 miles. A spare tire isn’t meant to completely replace a tire, rather, its purpose is to tide you over until you can properly replace it.
Additionally, you shouldn’t drive faster than 50 mph on a temporary or donut spare tire, as they have far less traction and durability than a standard tire.
You probably wouldn’t want to drive longer or faster on a spare anyway, as the typical spare can make your vehicle feel more like an airplane ambling down a runway than a car driving down a highway.
Once you are driving your spare, you should replace it with a proper full-size tire as quickly as possible to stay safe on the roads.
Types of Spare Tires:There are several kinds of spare tires, but which one you will use mostly depends on the type of vehicle you’re driving.
These vehicles are significantly heavier than most sedans and mid-sized cars, so the spare tires are usually larger to support the vehicle’s full load, and possibly additional cargo or items being towed.Full-size spares are typically much better quality than a donut spare; however, they still should be replaced as soon as possible. These spares often aren’t as durable, may have narrower wheels than the standard tires, and may not be produced by the same manufacturer as your other tires.
Full-size spare tires should be regularly inspected too, especially if they are secured to the bottom of the vehicle and therefore may be exposed to harsher elements.
How to drive safely on a spare tireRegardless of whether your spare is a donut or a full-size spare, you’ll want to be careful while driving on it. To drive safely on your spare tire, follow these best practices:
Spare tires often have different inflation pressure needs than your regular tires, so it’s wise to check them for proper inflation. Plus, a spare tire isn’t much help if it has low pressure.
Many spare tires have a lifetime of about eight years.As the Midwest’s premier driving school, Top Driver takes pride in preparing our students for everything they encounter on the road and with their vehicle.

Spare tires are useful insurance, but most are not designed to replace a flat tire indefinitely.
Not all spare wheels are created equal, and to better understand which spare tire your vehicle is equipped with, please refer to your vehicle owner's manual. Temporary spare tires generally do not have the life expectancy that regular tires do. Unlike a normal car tyre, spare tires can only have one polyester ply in the sidewall and two steel belts with a ply of polyester in the tread, meaning they can't provide half the performance and safety that an average tire can provide.
In this article we will try to describe all types of spare wheels available, and tell you how long you can drive on each of them.
These little spare tires are commonly referred to as donuts or space savers. They are very popular because they are lightweight and do not take up much space in the luggage compartment of your car. Due to the low weight, even a person who is not at all predisposed to physical activity will not find it difficult to lift and install such a spare wheel.
By the way, how to do it in the field, without the help of specialists, read here.
However, because the donuts are smaller and lighter, they lack two key features of conventional tires: strength and stability. Most of these spare tires have a speed limit of up to 90 km/h. With such a spare tire, you can expect to cover a distance of 80 km, some of them can cover up to 110 km. This should be enough to find the nearest tire shop and fix the damaged tire, or find a shop where you can buy a brand new tire if the previous one is no longer repairable.
From the above, we can conclude that the donut spare wheel is not recommended for long trips or pulling with its replacement with a normal, standard wheel.
Some car manufacturers fit their vehicles with full size spare tires. They are, of course, heavier than space savers and take up much more space in the trunk, but they are more durable and durable. They are able to last you much longer than donuts.
However, these tires may have a different tread pattern or rubber compound than a conventional tire. This can affect overall handling and safety on the road.
Although these tires are more durable, they are primarily designed to get you to your destination before you deal with the tire problem. In addition, do not forget that the place for the spare wheel in the car is empty, and it should be filled as soon as possible before another tire is punctured.
If you do not have a spare tire in your vehicle, then your vehicle may be equipped with run-flat tires. BMW and MINI typically install these tires during production. This type of tire is tougher than other tires and can withstand a puncture and keep going. However, they are also not designed to be ridden forever.
Most run-flat tires recommend replacing as soon as you notice a puncture. As a rule, they are designed for a distance of up to 100 km in a punctured state, then they must be replaced.
Compared to regular tyres, running-flat replacements are not cheap. Some craftsmen can patch run-flat tires, but manufacturers do not recommend going down this path.
One of the advantages of these tires is that you can get to the nearest car wheel shop at speeds up to 80 km/h, i.e. almost like a breeze.
Every motorist should remember that any type of spare tire is only there to keep you moving forward and replace a punctured tire as quickly as possible. The spares are a temporary replacement, and s, while full-size spare tires may look exactly like the rest of your car, they don't have the same performance as s and can get you in trouble on the road.
Remember, your car's tires are the only thing that keeps you and your passengers on the road, so you should never speculate on your own safety or the safety of those around you.

Sometimes, as a result of road accidents, two or three wheels break through at once. There is no time to mess around with disassembly on the spot, and I don’t want to get my hands dirty either. To get out of the situation, you have to go as is. Instead of one damaged wheel, a spare tire is placed, and the second and third are used in a deflated state. How long can you drive like this and how will such a journey turn out for tires?
Normal car tires are not designed to run without pressure. If the damage is minor, then it is better to repair the wheel on the spot. A puncture does not bleed air quickly, and sometimes just pumping up a tire is enough to have half an hour of time left, which is enough for a trip to a tire shop.
If the hole does not allow a long drive, then a self-tapping screw can be screwed into it, which will temporarily turn into a patch.
Then you can inflate the tire, which can keep the pressure at 1.7-2.1 atm for several hours. It is better to ride on inflated wheels.
Sometimes it happens that an inexperienced driver, even noticing a gradual release of pressure in the wheel, is too lazy to put on a spare tire, continues on his way, trying to find a tire shop, and arrives there already with a completely flat tire. It is absolutely impossible to do this. There is a high risk of complete damage to a generally still workable tire. Even a hundred meters for a flat tire are critical. The rubber begins to “chew”, the cord is damaged, the layers are compressed and cracked.
After such a trip, if you remove the tire and look at its inside, you will find black dust. It is a surface sealed layer. With subsequent pumping, hernias, similar to blisters, swell. They go in a chain along the diameter of the damaged cord threads. Then the wheel “killed” by the driver can only be sent to a landfill.
Thus, driving on flat tires is possible only in extreme cases, when the tire is already badly damaged and cannot be repaired, and the “reserve” has already been installed in another place.
Then it is necessary to drive only along the side of the road so that the disc has soft ground under it. Periodically you need to stop and inspect the wheels. When disassembling a flat tire, there is a risk of disc breakage, so the range of such a trip should not exceed 2-3 km.
From the point of view of the law, such a movement is permissible. In accordance with clause 2.3.1. SDA of the Russian Federation, if malfunctions occur along the way with which the operation of vehicles is prohibited, the driver must eliminate them, and if this is not possible, then he can proceed to the place of parking or repair, observing the necessary precautions. In other cases, it is better to still call a tow truck.
There are wheels that can move even with a complete loss of pressure. They are called Run-Flat. In their design, they have a very strong sidewall. In the event of punctures, the rigid inserts can take the weight of the vehicle and allow you to travel at speeds up to 80 km/h for distances up to 80 km.
