At Superior, we often get the question, “I know the size of my rims, but what are all the other numbers on my tire”? Well, one of the numbers you already figured out, and that was your rim size. On your tire it is designated with an “R” then a number which is your rim size. The “R” indicates a radial tire, which is the most common tire you’ll see on passenger vehicles, vans and most trucks.
Here’s a quick video that explains your tire’s coding system accurately and simply:

Tire Class – “P”
The first character(s) in a tire size designate the tire’s class. In this example, “P” indicates that the tire is a passenger car tire. An “LT” before the tire size designates a light truck tire, and no letter before the size indicates that it is a European metric tire.
Section Width – “205″
A metric tire’s section width is measured in millimeters. This measurement is taken from sidewall to sidewall. In this example, the section width of the tire is 205mm.
Aspect Ratio – “65″
This number refers to the height of the sidewall. It is a percentage of the section width. In this example, 65 percent of the section width of 205mm equals 133.25.
Tire Construction – “R”
The “R” in this example indicates radial tire construction.
Wheel Diameter – “16″
This indicates the wheel diameter in inches.
