tire

Abstract

To improve wet performance and resistance to uneven wear while maintaining low rolling resistance. [Solution] The area between the outermost open ends 20a in the tire width direction of each circumferential main groove 20 (22) in the tire width direction is defined as the center region W, and multiple shallow grooves 40 are provided in each land portion 30 (31, 32) of the center region W, with a groove depth of 30[%] or less of the circumferential main groove 20, the ratio of the total groove area of ​​the center region W is in the range of 25[%] to 40[%], the groove area of ​​the shallow grooves 40 is in the range of 10[%] to 35[%] of the total groove area of ​​the center region W, and the width of the center region W is in the range of 45[%] to 70[%] of the cross-sectional width of the carcass layer.
