<p>A tire having a tread of excellent low heat generation properties in which the rolling resistance is reduced without impairing the tire performance such as the grip performance. More specifically, a tire, having a tread composed of two or more layers of laminate rubber, where the land is formed by a main groove and the tand of the outermost layer is made lowest in the tread at least on the side face of the land. Preferably, the tire is formed such that the tand of the outermost layer is set at 0.07 or less, the thickness of the outermost layer is set to within 30% of the thickness of a cap rubber layer, and a rubber composition used in the outermost layer is mixed with carbon black of a grade up to HAF.</p> |
