What do the numbers on the side of a tire stand for?

Answer The numbers on the side of tires mean the sizes and heights of the tire in question. If the numbers weren't there no one would know the tire size. More exactly... Taking 195/75R14 as an example...The first number is the measurment in milimeters of the widest part of the tread- The second number is the height of the sidewall in relation to the first number expressed as a percentage (the height of the tire is 75% of the first number) and the last number behind the R is the rim size in inches.


What does SR followed by a number mean on the side of a tire?

"SR" is an obsolete way of expressing the speed capability of a tire using a now largely discarded sizing standard. The size might read something like "P175/70SR13" under this old system. The same tire under the current sizing standard would read "P175/70R13 82S" In both cases the "R" means the tire is of radial construction, the "S" indicates the tire has a speed capability of 112mph.
