Tire Size and DOT Code

Tire Size is a part of the DOT Code along with the Plant where the tire was produced and the week and year when it was made.  Here we present the key to learning what the tire size is in the code.

Although this information is prominently displayed on the sidewall of a tire, it is also encoded into the DOT code which is required for all tires approved for sale in the USA.

The size information is contained in two characters which are located in the 3rd and 4th position of the DOT code which normally follows the pattern 


where the two red X's are used for the tire size.  Use the following table for the sizes that have been standardized.
