If you don’t know your tire size, it will be listed in the owner’s manual and on the side of the tires. You may also find it in the driver’s side door jamb near the tire PSI. It’s a series of letters and numbers.
The numbers following the R are what we’re interested in.
Let’s say the Chrysler PT Cruiser tire size is P205/55R16. In this case, your tire size is 16 inches, which means you’ll need 16-inch hubcaps for your PT Cruiser. Depending on the material, you can purchase a set of hubcaps on Amazon for as little as $60 once you have the right size.
