Abstract: 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.

Abstract: A pneumatic tire and an innerliner for use in a pneumatic tire are provided by the invention. The innerliner comprises a multilayer structure including a barrier layer and an adhesive layer. The barrier is a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine-content chlorinated polyethylene elastomer. The adhesive can include a nitrile rubber composition or an ultra high molecular weight elastomer. The present invention more specifically discloses a pneumatic tire comprising a carcass and an innerliner, said innerliner comprising a multilayer structure including a barrier layer and an adhesive layer, the barrier layer comprising a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine content chlorinated polyethylene elastomer, the high chlorine content chlorinated polyethylene elastomer having a chlorine content of between about 35 percent to about 45 percent and the low chlorine content chlorinated polyethylene polymer having a chlorine content of between about 25 percent to about 35 percent, wherein the high chlorine content polyethylene has a chlorine content which is at least 5 percentage points higher that the chlorine content of the low chlorine content polyethylene; the adhesive layer comprising a polymer composition for adhering the barrier layer to said rubber carcass; and wherein the innerliner provides an oxygen permeability of less than 250 cc-mil/100 in2-atm-day at 65° C. and good cold flexibility at −40° C.
