How can I find my vehicle's tire size?

Asked 3 months ago
To find the tire size for your vehicle, there are a few reliable methods you can use. One of the most straightforward ways is to look at the sidewall of your current tires. You will find a series of numbers and letters that provide important information about the tire size. The size is typically formatted as a combination of numbers and letters, such as P215/65R15. The first part indicates the width of the tire in millimeters, followed by the aspect ratio, which represents the height of the tire’s sidewall as a percentage of the width. The letter indicates the construction type, and the final number represents the diameter of the wheel in inches. Alternatively, you can also refer to the vehicle's owner manual, which usually contains specifications for recommended tire sizes. Additionally, some vehicles have a sticker on the driver's side door jamb that lists the correct tire size along with other essential information. If you want to confirm or explore different options, you can visit the Tire Rack website, where they provide a wealth of information regarding tire fitment.
