Summary Review

Using the tire size P215/60R15 92V, let's review what all the numbers and letters mean.

The P means passenger car tire in P-metric sizing. This is not a light truck application tire with load range C or better.

The 215 is the cross section or widest point in the casing measured in millimeters.

The 60 is the Aspect Ratio of the tire. The sidewall height of this tire is 60% of its measured section width.

No, the R does not mean rubber or race. It is a radial ply construction tire. The casing plies are laid out radially to the center of the tire.

The 15 is the diameter of the wheel, in inches, that the tire is to be mounted on.

The 92 is the load index. Refer to the load index chart of a tire guide and you will find the maximum load carrying capacity of this tire to be 1389 lbs.

The V is the speed symbol or speed rating of this tire. In terms of speed, this tire is designed to go a maximum of 149 mph.

And finally, the 92V is called the Service Description. That is the load index and speed rating together.
