To provide a tire with a tread that promotes reduced internal heat build-up during service, particularly relating to truck tires.
A pneumatic tire comprises an outer tread cap rubber layer and an internal rubber layer underlying the outer tread cap rubber layer, in which the rubber composition of the tread cap rubber layer is composed of: (A) elastomers composed of (1) 65 to 90 phr of cis 1,4-polyisoprene rubber, (2) 5 to 25 phr of cis 1,4-polybutadiene rubber, and (3) zero to 12 phr of 3,4-polyisoprene rubber; (B) 1 to 8 phr of higher fatty acid salt; (C) zero to 20 phr of hydrocarbon resin; (D) 45 to 70 phr of reinforcing filler; and (E) a curative agent for the rubber composition composed of sulfur and sulfur cure accelerator where the sulfur cure accelerator is composed of a combination of primary sulfur cure accelerator and secondary sulfur cure accelerator.
