摘要

The vehicle pneumatic tire comprises a profiled tread (1) which is divided into profile ribs or block rows (3) by a number of circumferential grooves (2). The profiled tread has a main section (1a) made of a rubber compound, where another soft rubber compound is formed at a rubber layer (4) with high molecular weight plasticizer. The high molecular weight plasticizer is a liquid diene-polymer, such as liquid polybutadiene.
