Pneumatic tyres for a vehicle

摘要

The vehicle pneumatic tire comprises a radial casing (3), a multi-layered belt (2) and a tread (1) made of a tread lower part (5) and a profiled tread upper part (4). The profiled tread upper part has multiple layers (4a,4b) made of different rubber compositions arranged one above the other in radial direction. The layers in the tread upper part have impact resilience different from each other, where the outer radial layer has the smallest impact resilience.
