The front tire must be between 305 and 355 mm wide, and the rear tyre must be between 365 and 380 mm wide. The diameter of the wheel rim must be between 328 and 332 mm (13") and the diameter of the wheels themselves must not exceed 660 mm (with dry-weather tires) or 670 mm (with wet-weather tires). The tires feature four symmetrical longitudinal grooves, which must be at least 14 mm wide and 2.5 mm deep. The tire manufacturers deliver new tires matching the specific track and the vehicle behaviour for virtually every grand prix.
