In addition to the tyre size, you’ll find several other markings on your tyre’s sidewall that provide important information:
DOT code: Indicates the tyre’s manufacturing date and location. The final four numbers indicate the production week and year.
Speed rating: A letter that denotes the maximum speed at which the tyre can safely operate.
Load index: A number that represents the maximum weight a tyre can carry at the recommended pressure.
Treadwear, Traction, and Temperature (TT&T) grades: Ratings that provide information about the tyre’s expected tread life, wet traction performance, and temperature resistance.
