Beyond identifying the kind of tire and wheel tread you will need, you also need to find out the right size. There are many measurements essential to know if the tire fits your vehicle model, and this is a brief guide to transforming what these figures mean. The main of these will be the width and size, but other factors like rate rating may also be explained.
The main element is to check out the mixture of characters and figures on the wheel itself. They are a symbol of various measurements and other determining markers that help you select if you have the right wheel.
- Wheel Type
The first identifier is one/two characters. Cars in America state P, indicating it is a P-Metric wheel made for traveler vehicles. This does mean they uphold certain requirements in America.
Alternatively, when there is no notice, then this means it is a Euro-Metric wheel, which includes different weight capacities. There’s also tires designated LT, this means the wheel was produced for light vehicles. These auto tires need higher pressure than traveler auto tires because of the strain.
- Car tire Width
This identifies the dimension of the tire’s width in millimeters, in one sidewall to some other. These are a symbol of the first 3 digits, this means in a car tire proclaimed P215/65 R15 91S, it offers a width of 215 millimeters.
- Aspect Ratio
Another two numbers following the slash mark make reference to the aspect proportion or the proportion of the car tire cross-section’s elevation to the width. In the example above, this implies the tire’s elevation is approximately 65% of the width. When the aspect proportion is bigger, then your sidewall is also bigger.
The next notice means the structure of the car tire, where in fact the R in the example means Radial.
- Steering wheel Diameter
This number means the steering wheel size measured in one side to some other. It also establishes which wheel the car tire is meant to match. In the example, this implies the car tire is produced for a steering wheel which has a 15- in. Diameter.
- Fill Index
Another two numbers make reference to the strain index, of the utmost fill that the wheel can support when it’s inflated properly. The same information is also on the both in pounds, sidewall and kilos.
- Rate Rating
The last notice stands for the utmost speed capacity for the wheel. Each letter means a certain traveling rate, which manufacturers advise that owners do not surpass.
This alphanumeric mixture is available on the wheel itself, as well as the entranceway jamb on the driver’s part, inside the entranceway of the glove package, and within the hatch of the vehicle’s gas tank. You may even find out about it in the manual of your automobile.

These letters are a symbol of Uniform Car tire Quality Grading, which is defined by the Section of Transport of the united states as a ranking system to see consumers on specific factors. First is the traction force grade, stating the way the car tire performs in moist conditions. If it comes with an AA ranking, then this means it has excellent traction force when the streets are moist. Second, temperature levels will determine the tire’s capability to withstand high temperature, meaning a car tire with an increased temperature quality can still perform at higher rates of speed. Lastly, treadwear levels are a symbol of the tire’s performance on standardized federal government lab tests that foretell how long the car tire can last. For instance, a tire which has a 200 treadwear quality will last twice so long as one with only a 100 treadwear quality.
