To optimize tire characteristics such as rolling resistance and comfortableness by continuously reducing tread thickness between a tread face and a breaker from the tire equator to the outer end of the breaker and providing a self-sustaining ability for a rubber wall part having a load supporting layer.
A tire for a vehicle is provided with a breaker 5 arranged on the outside of the carcass 1, that is, on the inside of a tread part 6. A tread face 68 is curved in a convex shape, while in a normal internal pressure condition, a tread thickness T between the tread face 68 and the breaker 5 is continuously reduced from the tire equator to the eternal end part 10 of the breaker 5 because the breaker 5 is extended evenly. The rubber wall part 7 of the tire is provided with a load supporting layer 14 so as to exhibit self-sustaining ability. The load supporting layer 14 is constructed of a double layer consisting of reinforcing rubber layers 11, 12. In this way, tire characteristics can be optimized with good balance.
