FIELD: tyre industry; radial pneumatic tyres. SUBSTANCE: cord layers are arranged in tyre so that thickness of rubber interlayer between threads of carcass cord and inner surface of tyre is 3.0-4.0 of diameter of carcass cord thread, and thickness of rubber interlayer placed between layers of carcass and breaker is 0.9-1.5 of diameter of carcass cord thread. If more than one cord layer is present in carcass, thickness of rubber interlayer between threads of cord in adjacent layers of carcass is within 1.1-1.2 of diameter of carcass cord threads. EFFECT: improved steerability of vehicle, increased wear resistance of tyre. |
