HOW DO YOU FIND THE TIRE SIZE ON YOUR VEHICLE?

There are a few ways to find your vehicle’s tire size. You can look on the tire sidewall (see image to the right), look in your vehicle’s owner’s manual or the vehicle placard (typically found inside the driver’s side door). The numbers in the tire size represent the cross section, aspect ratio and rim size.
