How to Read tire size What you need to know about your vehicle’s tire size
WHY DOES TIRE SIZE MATTER?
When the time comes to replace your tires, what you choose matters. And yes, that applies to tire size.

The best way to ensure top performance out of your vehicle is to know how to find and how to read tire size recommended by your car’s manufacturer.
