What do the numbers on a tire mean? The DOT number appears on the sidewall of all tires intended for sales in the U.S., and designates the location of manufacture, the week and year of production, and the specific tire.
Because we know that the tire size shown in this example has a section width of 8.86 inches and the aspect ratio is 45%, the sidewall height for this tire is 3.98 inches: (8.86 inches) x (.45) = 3.98 inches.
