摘要

PURPOSE:To improve the durability by preventing a stone from jamming into grooves formed on the tread of a tire in the circumferential direction. CONSTITUTION:This pneumatic tire T is provided with stone jamming preventive projections 3 formed continuously in the circumferential direction from the bottoms 2A of the circumferential grooves 2 of a tread 1. The stone jamming preventive projection 3 is made in a wave form providing curved line concaves 3A and curved line convexes 3B alternatively on its outer peripheral surface in the circumferential direction.
