摘要

A pneumatic tubeless tire without an innerliner having a topping rubber layer which includes aligned casecords therein; a rubber composition for the topping rubber layer containing no plasticizer and comprising 100 parts by weight of a rubber component consisting essentially of 50 to 90% by weight of a diene rubber and 50 to 10% by weight of a brominated isobutylene/p-methylstyrene copolymer, and 1 to 10 parts by weight of a tackifier. According to the present invention, there is a durable and lightweight pneumatic tubeless tire without an innerliner in which the topping rubber layer has superior adhesion properties to the embedded casecords and other tire members containing diene rubber.
