There are three things to understand when buying new tires for your car; the size, speed rating, and load index. Making the correct selection is very important to maintain optimal performance, safety, and fuel efficiency.
Fortunately, all of this information is easy to find. You can locate it inside the driver’s door on your car, inside the fuel flap, or inside the glove compartment. Alternatively, you can consult your vehicle documentation and tire manufacturer specifications.
When considering tire size, there are two simple rules to follow.
Firstly, the replacement tires should be the same size, load index and speed rating specification as recommended by the vehicle or tire manufacturer.
Secondly, the replacement tires must never be of a smaller size or load-carrying capacity than the original specification.
What do all these letters and numbers mean? Here’s all the information on the tire sidewall quickly decoded:
The documentation supplied with your vehicle outlines the recommended tire sizes for your car. Compatibility is determined according to its outer dimensions – diameter/rolling circumference and width – and labeled as a standardized tire size indicator on the sidewall.
Also, the size must comply with the vehicle’s requirements regarding speed rating and load range. Together, the load index and speed index make up the full service description for a passenger car tire. It must correspond to the information provided in the vehicle documents.
The load index rating is the maximum capacity of a passenger car tire, calculated from the maximum permissible axle load range between two tires.
The speed index rating is also a relevant factor when choosing a tire. The tire’s speed capability must be at least equivalent to the top speed of the vehicle. Its speed rating indicates the maximum permissible speed (at full load) of a tire, and whether it’s appropriate for your car.
Make your tire size selection in strict accordance with vehicle documents and tire manufacturer recommendations.
If the combined wheel and tire diameter aren’t correctly matched, there may be drastic differences in ride height and speedometer readings.
For example, fitting 17-inch-diameter wheels to a car that is designed to have 14-inch-diameter wheels will change the ride height. That means the car body will be higher off the ground. There will also be a slight increase in top speed, and the speedometer will no longer be accurate. Last but not least, the car will accelerate slower.
Switching to different tire sizes can only be done in compliance with all legal requirements and regulations – plus the recommendations of the vehicle, wheel, and tire manufacturers. At the very least, the wheel must have complete freedom of circular motion and the tire’s adequate load capacity must be observed.
The internal construction of tires fitted on any vehicle must either be radial or bias-ply. Fitting mixed tire constructions (bias-ply and radial together) for cars, caravans, and other light trucks is unsafe and illegal.
The only permissible exception is the use of a spare tire for an emergency.
Concerning the choice of wheels or rims, the same guidelines apply. Motorists must use the standard wheels or rims approved by the vehicle manufacturer as recommended.
For optimal safety and performance, replace all four tires at the same time. While it is possible to switch out less than four tires at the same time, you should follow a couple of guidelines regarding tire size.
If only replacing one or two tires, for example, ensure that each one is the same size and has the same load index and speed rating as specified by the car manufacturer.
When replacing only two tires, fit both of them to the wheels on the rear axle. The reason for this is that the newer tires will have much better grip, particularly on wet roads, and reduce the risks of hydroplaning.
Replacing only a single tire is not advisable, as it can impact vehicle suspension or transmission and produce excessive wear on the tire tread.
But if replacing only one tire is unavoidable, then pair the single replacement tire with the tire that has the deepest tread depth, then fit both to the rear axle.
The fastest way to the perfect tire.

Once you have determined it’s time to buy tires, you’ll need to know what size tires are correct for your vehicle. Depending on what you drive, you may be interested in how to find the right tire for your…
This information is usually inside your car’s doorjamb, in your owner’s manual.
To ensure your current tire or a replacement tire you may be looking at matches your vehicle’s requirements, it will be good for you to understand how tire sizing works. You may have never paid attention to the string of numbers and letters on every tire, but it’s a gold mine of information.
If you’re unsure of how to read tire measurements from your tire walls, the information and graphics below will tell you how to read tire size, understand and interpret it. If you decide you want to substitute a new size or tire type, consult an authorized tire retailer who can expertly advise you, because many optional tire sizes may have different load capacities and could require wheels of a different rim width or diameter and different inflation pressure.
Not sure you need new tires? Our Tire Replacement Guidance article will help you determine whether it’s time to retire your tires.
Most passenger cars, SUVs and light pickups (1/2 ton and smaller) will come with tires that are either P-Metric or Euro-Metric.
For P-Metric tires, you’ll see the letter “P” before the number sequence begins: P225/70R16 97H. P-metric is a designation standardized by the Tire and Rim Association for a “passenger car” tire type. For Euro-Metric there will be no preceding letter before the number sequence begins: 225/70R16 98H. Euro-Metric is a designation standardized by the European Tyre and Rim Technical Organization for a “passenger car” tire type. Both P-Metric and Euro-Metric size tires are designed to primarily be used on passenger vehicles, which can include cars, minivans, SUVs, and other light duty pickup trucks.
If your vehicle is an SUV, Pickup truck or van, you might see a different type of size designation on your placard that is specific for heavy duty light trucks and vans, especially common on ¾ ton and larger pickup trucks and vans. There are two common size types in this category, LT-Metric and Euro-Metric Commercial (aka C-type). Both size types are metric and so use the same structure as P-Metric and Euro-Metric but have some different characters in the size that differentiate them from their passenger car cousins.
LT-Metric tires will have the letters “LT” before the size number sequence: LT245/75R17 119/116R Load Range E. Notice that there are two load index numbers and a Load Range, see the section on Load Index for more info. LT-Metric is a designation standardized by the Tire and Rim Association for a “light truck” type tire. Euro-Metric Commercial or C-Type tires will look very similar to a passenger Euro-Metric size except that there will be a “C” right after the rim size: 23/65R16C 121/119R. Notice that the C-type tires also have two load index numbers. Euro-Metric Commercial, or C-Type is a designation standardized by the European Tyre and Rim Technical Organization for a light truck type tire. Light truck tires are designed to be used on vehicles capable of carrying heavy cargo and are usually only specified by a vehicle manufacturer on vehicles exceeding a certain load capacity.
Other types of tires that fall into the Metric sizing type are Temporary Spares, they start with “T”.
If you see a size that starts with “ST,” that means “special trailer” and is only for use on a trailer.
Regardless of whether you are looking at a P-Metric, Euro-Metric, LT-Metric, Euro-Metric Commercial, T or ST tire the numbers in the size mean the same thing.
The first number to appear in your tire size information is the width, in millimeters, of the correct tires for your vehicle: P225/70R16 91S.
Tire width always refers to the measurement from one sidewall to another. Thus, a tire with the measurement “P225” is for a passenger vehicle and has a nominal width of 225 millimeters.
After the slash mark, the next number you see is for the tire’s aspect ratio, which essentially tells you how tall your tire’s profile is: P225/70R16 91S. Aspect ratios are delivered in percentages. Tire makers calculate the aspect ratio by dividing a tire’s height off the rim by its width.
If a tire has an aspect ratio of 70, it means the tire’s height is 70% of its width.
Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series, but a typical trade off can be ride harshness.
After the aspect ratio comes a letter that indicates the type of internal construction maintaining your tire’s stability: P225/70R16 91S.
There are two types of construction that you may see on the sidewall of a tire:
Radial tires are the most common tires on the road in the United States today; thus “R” will usually be shown in the tire size designation. Radial construction means the tire’s internal ply cords are oriented in a radial direction, from one bead over to the other, essentially perpendicular to the direction of rotation.
You may also occasionally see RF indicating a run flat tire or ZR indicating a tire that is a speed rating higher than V.
The next number is the diameter code, in inches, of the rim onto which the tire can be mounted. For example, a tire with the P225/70R16 91S would fit a rim with a 16-inch diameter.
Load index can be a confusing subject because there are so many different caveats, but we will try to explain everything here.
The next figure after the rim size in the sequence is your tire’s load index, which tells us how much weight, in pounds, the tire can support when fully inflated: P225/70R16 91S
We call it the load “index” because the number doesn’t tell us the precise number of pounds the tire can carry, at least not by itself. However, the number does correspond to a specific load capacity listed in an index.
Beginning with 1 and ending with 150, numbers in the load index represent carrying capacities of 99 to 7385 lbs.
There are two types of load types for passenger tires though, Standard Load and Extra Load. If a tire is Standard Load there will be no markings indicating it but if it is Extra Load the letters XL will appear after the size and load index.
Standard Load Euro-Metric: 215/55R17 94V
Extra Load Euro-Metric: 215/55R17 98V XL
Passenger car tires like P-Metric and Euro-Metric will only have one load index number where LT-Metric and Euro-Metric Commercial (C-Type) will have two numbers separated by a slash. The first number is the load index if the tire is used in a single application, the second number is the load index if the tire is used in a dual application. Passenger type tires cannot be used in a dual application. Light truck tires will also have a Load Range that is indicated by a letter, such as Load Range E. Load Range is an older term that is still commonly used in the industry so you may hear your tire dealer reference it but the load index numbers are the best way to ensure you have the proper tire.
One important but often misunderstood facet about load index is that the load index numbers between standards organizations (P-Metric vs Euro-Metric) are not necessarily on the same scale. Meaning that two tires in the two different systems that have the same load index number could have different maximum load capacities. This is why it’s important to not only look at the load index number but also verify the actual load capacity.
The final figure in a tire size sequence is the speed rating, which is indicated by a letter: P225/70R16 91S. Just as your load index number corresponds to a specific load, your speed rating letter corresponds to a particular speed capability based on a standardized laboratory test.
For example, a tire with speed rating “S” is rated for up to 112 mph, while a tire rated “R” is up to 106 mph. Remember that this isn’t a recommended cruising speed. Of course, you should always follow legal speed limits on roadways.
Replacement tires must have the same or higher speed rating as the vehicle’s Original Equipment to maintain vehicle speed capability. If a vehicle has tires with different speed ratings, it is the speed rating of the “slowest” tire that dictates the vehicle top speed.
There is one last sizing type that you should know about, especially if you are in the market for off road tires for a light truck or SUV. It’s called a Flotation size and the numbers in this sizing format are very different from the Metric formats. Flotation sized tires are similar to LT-Metric tires in application except for a few important points. Number one, they cannot be used in dual applications and number two, an equivalent size tire may have different load capacity than its LT-Metric counterpart.
The first number in the Flotation tire size is the overall diameter in inches.
Pretty straight forward.
The second number is the section width (sidewall to sidewall) measurement in inches. Again, fairly simple.
After the section width comes a letter that indicates the type of internal construction: 33X12.50R17LT 120Q.
This is the same as is found in the metric sizing systems.
There are two types of construction that you may see on the sidewall of a tire:
Radial tires are the most common tires on the road in the United States today; thus “R” will usually be shown in the tire size designation. Radial construction means the tire’s internal ply cords are oriented in a radial direction, from one bead over to the other, essentially perpendicular to the direction of rotation.
The next number is the diameter code, in inches, of the rim onto which the tire can be mounted.
For example, a tire with the 33X12.50R17LT 120Q would fit a rim with a 17-inch diameter.
The letters LT will be after the Rim Diameter indicating that this tire type is intended for Light Truck vehicles similar to the LT-Metric and Euro-Metric Commercial (C-Type) tires.
Load Index and Speed Rating have the same meaning and format as the tires using the metric sizing system. Note that since flotation tires cannot be used in a dual application there will be only one load index number instead of two.
Another group of stamping on certain types of tires is the Uniform Tire Quality Grading or UTQG. This grading and stamping is required for passenger car tires (i.e. P-metric and Euro-metric) in the all season and summer categories.
Dedicated winter tires, Light Truck (LT-Metric, Euro-Metric Commercial, Flotation) and Motorcycle tires are excluded from this requirement.
Quality grading is designed to make the tire purchase decision easier for you. Ideally, the system is intended to provide simple, comparative data so you can make an intelligent buying decision. However, the ratings are based upon test results achieved under special conditions. This means it’s possible to misinterpret the comparative data as it relates to your individual driving habits, conditions, etc. You should still rely on your service or tire professional for assistance.
Quality grading designates the comparative performance levels of a tire based on government-specified tests but commissioned by the individual tire manufacturers. All tire manufacturers are required to grade regular and all-season passenger tires in three categories:
UTQG
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course for 6,000 miles (9,600 km).
For example, a tire graded 150 would wear one and a half times as well on the government course as a tire graded 100. However actual tire performance depends on driving habits, road characteristics, service practices, and other factors that can influence the outcome.
Traction Grades AA, A, B and C
The traction grades from highest to lowest are AA (the highest), A, B and C. They represent how well tires stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. C-rated tires will have the lowest traction performance.
WARNING: THE TRACTION GRADE ASSIGNED IS BASED ON A WET BRAKING (STRAIGHT AHEAD) TRACTION TEST AND DOES NOT INCLUDE CORNERING (TURNING) TRACTION.
Temperature Grades A, B and C
The temperature grades A, B, and C represent the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the tire’s material to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a performance level all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades A and B represent higher levels of performance on the laboratory test wheel than the minimum required by law.
WARNING: THE TEMPERATURE GRADE IS ESTABLISHED FOR A TIRE THAT IS PROPERLY INFLATED AND NOT OVERLOADED. EXCESSIVE SPEED, UNDER INFLATION, OR EXCESSIVE LOADING, EITHER SEPARATELY OR IN COMBINATION, CAN CAUSE HEAT BUILDUP AND POSSIBLE TIRE FAILURE.
DOT Quality Grades
All passenger car tires must conform to other federal requirements in addition to these grades.

When you need to buy a new set of wheels, the question - which tire fits which rim - becomes one of the most relevant among motorists.
Someone wants to slightly tune the car by choosing non-standard wheels, someone wants to improve the driving performance of the car or just choose the right option.
When choosing new tires for rims, you can always choose the simplest, but generally correct way - use a tire calculator or contact a specialist from a tire store. Although the task is not as difficult as it seems at first glance. We will analyze in more detail about the correspondence between the size of tires and wheels, and how to choose the right size for car tires.
Regardless of whether you choose summer or winter tires, the fundamental rule for an accurate choice is the correspondence between the technical parameters of the tire and the wheel.
Disks have several main characteristics - these are the diameter and width of the disk, the diameter of the central hole for the hub, the offset, the number of mounting bolts and the diameter of the circle of the centers of the holes for the fasteners.
Of all the parameters, the size of a tire is fundamentally affected by two characteristics - these are:
It is difficult to miscalculate with the diameter: it is impossible to install rubber with a 15-inch bore on R16 wheels. But to make a mistake with the width is quite likely, and this will instantly affect the driving performance of the car and other characteristics.
However, the same applies to the profile height ratio. This parameter does not affect the selection of tires so much, but too low a profile loads the suspension, which accelerates the wear of the structural elements of the chassis + reduces the ride comfort on poor quality roads. Too high a profile will touch the wheel arches and fender liner, and this is already increased wear of the rubber itself.
In order to correctly select the ratio of "wheel + tire" - it is necessary to match the width of the rim to the width of the tread profile. If the tires are purchased for the original (regular) set of disks, it is enough to look at the factory characteristics of the disk, most often located on its inner side. The marking is standard for both cast and steel wheels, and contains three main values: diameter, width and offset (for example: J6 × 16 ET52, where 6 is the width of the wheel rim in inches, 16 is the outer diameter of the wheel, and ET52 - departure).
Instead of the designation ET, the inscription OFFSET or DEPORT may come across - it all depends on the country of manufacture of the car.
What do these parameters give? The two main characteristics are:
In particular, we will analyze the question - what tires are suitable for 16 rims?
When choosing the diameter of a tire, there is a direct relationship between dimensions, that is, the outer diameter of the disk and the landing diameter of the tire must have the same value - and in the marking this indicator is indicated as R16.
Next, you need to select the tire tread width.
The first rule to understand is that the width of the tire should not, but can be 25% more than the width of the wheel rim. This is due to the fact that automotive rubber, due to the composition of the rubber mixture, has high elasticity, and with a difference of 25%, it “sits” on the wheel much denser than if the width of the rim and tread had a direct relationship between dimensions, that is, the same indicators.
However, the width of the rim is indicated in inches, and the width of the tire profile in cm, for example: the width of an R16 rim in inches can vary from 5.5 to 9 inches (this figure should be found on the inside of the rim). Thus, to determine the nominal value of the tread width, the rim width parameter in inches must be converted to cm. you need 6 × 25.4 = 152.4 cm - this is the nominal value of the width of the rim of your wheel.
If you need to determine which tire size fits which wheels, then in the calculation you need to start from the tread width.
In particular, with a tire profile width of 225 cm, this figure must be divided by 25.4 mm (1 inch) - we get a value of 8.85 inches. 25% must be deducted from the resulting figure (admissible increase for tread width). With a simple calculation, the resulting figure for the rim width is 6.63 - round up to 7 and get the allowable rim width (J7) for a tire with a tread of 225 cm.
This calculation is suitable for any type of road transport (compacts, SUVs, commercial and trucks): using this method, you can correctly calculate the tire width for 17, 18, 19 inch wheels and also pick up tires for 13 inch wheels. If you are afraid of making a mistake in the calculation, you can use the rubber-to-rim ratio table or, as mentioned at the very beginning, select the parameters online using the visual tire and wheel compatibility calculator.
The issue of selecting tires for disks has always been relevant for motorists, since every self-respecting driver needs to know certain parameters.
If the characteristics are not known and these parameters are not followed, the car will experience a significant deterioration in performance, which seriously threatens safety.
In order to match tires to the wheels as accurately as possible, you should first study the marking of the wheels:
Wheel marking with dimensions R13 4x98 ET35 J5 D58.6
It is the latter that has a major role in matching tires and wheels. In order to choose the right wheels for tires on passenger cars, you can use the table compiled by the specialists of Avtotire Kom. Or you can use the selection of wheels for the car by clicking on the link .
