Abstract:
To provide a tire that can make both uneven wear resistance and wet performance compatible, at the time of high-load running.SOLUTION: The tire comprises a tread part 2 whose direction of mounting on a vehicle is designated. Two circumferential grooves 3 of the tread part 2 are constituted of outer circumferential grooves 5 and inner circumferential grooves 6. Three land parts 4 of the tread part 2 are constituted of outer shoulder land parts 7, inner shoulder land parts 9 and crown land parts 8. A center 8c in a tire axial direction of a grounding surface 8s of the crown land part 8 is positioned closer to an inner tread end Ti than a tire equator C. A plurality of crown lateral grooves 14 are formed in the crown land part 8. The plurality of crown lateral grooves 14 respectively extend in a tire axial direction from the inner circumferential grooves 6 and terminate at sides closer to the inner circumferential grooves 6 than a tire equator.
