Pneumatic tyres for a vehicle

摘要

The tire has running strips (1) including finger shaped layers (7b, 8b) running in a radial direction. The layers are made of rubber compounds of different hardness. The layers are formed by finger-shaped extensions which are interconnected with each other. The extensions run from a primary layer (7a) of a running strip-lower part (7) toward a periphery of the strips, and from an external layer (8a) of a running strip-upper part (8) toward a belt assembly. Rubber compounds of the strip-lower part and the strip-upper part include consistent abrasiveness.
