    摘要： To enhance uneven wear resistance with achieving higher levels of dry grip performance and wet performance, a tread surface 2 is provided with one circumferential main groove 3 in an outer region 2o thereof directed outward of a vehicle and with first and second circumferential main grooves 4 and 5 in an inner region 2i thereof directed inward of the vehicle, a central region Rc between the circumferential main grooves 3 and 4 is formed into a rib 10 extending continuously in the circumferential direction, an outer shoulder region Ro between the circumferential main groove 3 and TEo is formed into a row of outer blocks 12 defined by inclined main grooves 6, and the outer blocks 12 are provided with inclined sub-grooves 13 having an inclination direction different from that of the inclined main grooves 6, thereby dividing each of the outer blocks 12 into a first block portion 12A on a tire equator side and a second block portion 12B on a ground contact edge side.

    摘要： A tire 1 comprises a tread portion 2, a tread edge Te provided in the tread portion 2, a shoulder main groove 3 extending continuously in the tire circumferential direction in the tread portion 2, and a shoulder land region 5 being defined between the tread edge Te and the shoulder main groove 3. The shoulder land region 5 is provided with a shoulder lateral groove 10 connecting between the shoulder main groove 3 and the tread edge Te and a first shoulder lug groove 11 extending axially inwardly from the tread edge Te and terminating within the shoulder land region 5. An angle θ1 of the shoulder lateral groove 10 with respect to the tire axial direction is larger by 10 to 40 degrees than an angle θ2 of the first shoulder lug groove 11 with respect to the tire axial direction.
