Abstract
This invention relates to pneumatic radial tires which exhibit improved rolling resistance (provide better fuel economy) and improved performance characteristics. More particularly, this invention relates to the structure of radial ply tires for heavy load vehicles such as trucks, buses, and the like. It is based upon that finding that a defined profile of the outer surface of the sidewall portion can lead to a tire with reduced rolling resistance and a reduced generation of heat. The reduction in rolling resistance is obtained by a specific shaping of the bead portion of the tire which allows a bead mass reduction with an acceptable trade-off with regard to bead durability.
