To determine the size of tires for your vehicle, you can refer to the information provided on the tire sidewall or in your vehicles owners manual. The tire size is typically expressed as a series of numbers and letters, such as P225/70R16 91S. Heres a breakdown of what each part of the tire size represents:
- The first letter, "P" or "LT", indicates the type of tire. "P" stands for passenger vehicle, while "LT" stands for light truck.
- The first number represents the width of the tire in millimeters, measured from one sidewall to another.
- The next number is the aspect ratio, which is the tires height in relation to its width.
- The letter "R" indicates the construction of the tire, with "R" standing for radial construction.
- The following number represents the wheels diameter in inches.
- The last part of the tire size, such as "91S", refers to the load index and speed rating of the tire.
If you are considering changing the tire size, its important to consult with a tire professional to ensure that the new size is compatible with your vehicles specifications and requirements. Additionally, different tire sizes may have different load capacities and could require wheels of a different rim width or diameter, as well as different inflation pressure.
Ultimately, understanding how to read tire size is crucial when it comes to purchasing the correct tires for your vehicle, and consulting with an authorized tire retailer can provide expert advice on selecting the right tire size for your specific needs and vehicle.
