Abstract
Rubber compositions for tire treads of an all-weather type are disclosed which are so designed as to exhibit high dynamic Young's modulus, sufficient resistance to snow and ice skidding, to abrasion, to cracking and to crack growth and adequate durability. A selected base rubber is combined with a selected carbon black and a selected m-cresol resin. The base rubber is a blend of two different rubbers, one being natural rubber alone or a combination with a diene rubber and the other being butadiene rubber. The carbon black has specified absorptivity of iodine and dibutyl phthalate. The m-cresol resin is a novolak condensate.
