Pneumatic radial tire having belt reinforcements |
摘要 |
Pneumatic radial tires are disclosed which are comprised of two or more belt plies reinforced respectively with an aramid fiber cord and a steel wire cord. Both cords are coated with one and the same rubber composition made up of a selected class of starting rubbers, sulfer, resorcinol and/or its precondensate, hexamethoxymethylmelamine and a selected class of cobalt compounds derived from organic acids. The belt plies excel in water-resistant adhesion and heat resistance and thus have freedom from ply separation, contributing to a radial tire of improved durability.
