To determine your hubcap or wheel size, start by finding a series of 9 letters and numbers on the side of your tire that begins with the letter “P”.
At the end of this series, you will see the letter “R” followed by 2 numbers. These last two numbers are your hubcap or wheel size.
Although hubcap and wheel sizes are referred to in inches, they are NOT a physical measurement of the diameter of the hubcap or wheel.
So don’t worry about measuring, Just refer to the tire code when ordering hubcaps or wheels and get it right every time!
