1. P indicates that the tire is for passenger

vehicle use.

2. The width of the tire from sidewall edge to

sidewall edge in millimetres.

3. The aspect ratio, also known as the profile,

gives the sidewall height as a percentage of

the tread width. So, if the tread width is 205

mm, and the aspect ratio is 50, the sidewall

height will be 102 mm.

4. R indicates that the tire is of Radial ply

construction.

5. The diameter of the wheel rim given in

inches.

6. The load index for the tire. This index is not

always shown.

7. The speed rating denotes the maximum

speed at which the tire should be used for

extended periods. See 177, SPEED

RATINGS.

8. US DOT Tire Identification Number (TIN).

This begins with the letters DOT and

indicates that the tire meets all federal

standards. The next two numbers or letters

are the plant code where the tire was

manufactured, the last 4 numbers are the

marketing codes used at the

manufacturer’s discretion. This

information can be used to contact

consumers if a tire defect requires a recall.
