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.
Tire sidewall failure â A defect in the design or manufacturing process can lead to deterioration of the tireâs sidewalls. This can lead to an unexpected collapse and blowout. Tire sidewall failure also may be attributed to the use of defective or insufficient materials during production. Tire bead failure â A tire bead is responsible for maintaining the integrity of the tire. If this inner circle is not properly reinforced, the tire may lose pressure and be subject to tire blowouts.
