摘要： A tire is a tire in which circumferential grooves, and lug grooves comprising opening portion in tread end and which extend in the tread width direction from the tread end to the circumferential groove, are formed. Projection parts are provided in the groove bottom of the circumferential grooves. The projection parts extend from one side wall forming a circumferential groove to the other side wall opposite the one side wall. Multiple lug grooves are formed at predetermined intervals in the circumferential direction. In the tread surface view of the tire, given points of intersection as the points at which a circumferential groove extension that passes through a circumferential groove intersects with a lug groove extension that passes through a lug groove, the projection parts are provided between a first point of intersection and a second point of intersection adjacent to the first point of intersection in the circumferential direction.

摘要： An object of the present invention is to provide a pneumatic tire capable of facilitating heat dissipation of a tread portion thereof to lower temperature at the tread portion. Specifically, the present invention provides a pneumatic tire having in a tread surface at least one circumferential groove extending in the tire circumferential direction and plural lateral grooves, the lateral grooves each opening to the circumferential groove, having a wider groove width than the circumferential groove and extending to be inclined with respect to the tire circumferential direction, comprising: a recessed portion formed in a groove wall, facing the corresponding lateral groove, of the circumferential groove; and at least one projecting portion formed at a groove bottom of the circumferential groove between the recessed portions adjacent to each other in the tire circumferential direction.
