Best Answer

Say you have a tire size 205/60HR16:

205 is the section width of the tire in millimeters. Section width is the overall width from sidewall to sidewall. Tread width is typically 90% of the section width. In the above size, the section width is 205mm.

The second number is the aspect ratio. This is the percentage ratio of the sidewall height to section width. In the above example, the sidewall height is 60% of the section width.

The last number is the wheel diameter in inches. So in the above example, the wheel diameter is 16 inches.

The R in the size designation means the tire is a radial tire, as almost all car tires are. The letter in front of the R (H in the above example) is the speed rating of the tire. The speed rating is the maximum speed the manufacturer recommends for the tire.

What is tire size for 2001 Dodge Durango?

Tire sizes will be stamped into the side of every tire on the vehicle. The number will start with the letter "P". There should be 3 sets of numbers each indicating a different dimension of the tire. For example, (I am not saying this is the size of your tire) a tire might have the numbers P225 70 R14. The first number following the P is the width of the tire (tread portion). In this example the tire is 225mm wide. 70 would be the height of the tire in this example. The measurement is taken from the rim to the top tire. and R14 would be the radius of the rim. or 14" rims in this example.
