1. How to Determine your Tire Size
Knowing your tire size can save you time and help you to make an informed purchase. Your vehicle's original tire size can be found in your owner's manual or on the tire label located on the inside of the driver's door, glove box lid, or inside the fuel hatch. If in doubt, check your sidewall. Tires are specified in the form 225/50R16. The first number is the width of the tire (section), the second number is the aspect ratio (profile), and the third number is the wheel diameter (rim size).
