Title: PNEUMATIC TIRE
Abstract:
The purpose of the present invention is to reduce rolling resistance and noise while maintaining snow traction performance. The pneumatic tire 1 is equipped with multiple circumferential main grooves 10, multiple lug grooves 20, and multiple blocks 30. Raised-bottom parts 40 are formed on the groove bottom 44 of a shoulder circumferential main groove 13 that is a circumferential main groove 10 among the multiple circumferential main grooves 10 which is located on the outermost side in a tire width direction, and shoulder lug grooves 23 that are lug grooves 20 among the multiple lug grooves 20 which are located on the outer side of the shoulder circumferential main groove 13 in the tire width direction and which are connected to the shoulder circumferential main groove 13 from the outside in the tire width direction. The raised-bottom parts 40 are formed so as to exclude at least intersection parts 50 where the shoulder circumferential main groove 13 and the shoulder lug grooves 23 intersect.
