PROBLEM TO BE SOLVED: To reconcile the on-load performance with the off-load performance at a high level. SOLUTION: A tread grounding surface is divided into a central land part and side land parts by a circumferential main grooves G provided in both sides of the tire equatorial surface. The central land part is divided into central blocks B0 by a central inclined lateral main groove (g). The side land part is divided into a first - a fourth side blocks B1-B4 by a first and a second inclined lateral main grooves (ga), (gb) arranged each other in the circumferential direction from the circumferential main groove G to a tread grounding edge TE and a connecting inclined lateral main groove (gc) for connecting between the adjacent first inclined lateral main grooves (ga), (ga). Inclining direction of the connecting inclined lateral main groove (gc) is same with that of the central inclined lateral main groove (g) and different from that of the first and the second inclined lateral main grooves (ga), (gb). The number of each side block B1-B4 is same with the number of block of the central block B0. |
