Abstract

The invention relates to a vehicle tyre, which has a tyre carcass 6 and at least one surface covering 20 composed of two grades of rubber, the surface tread on the surface covering being formed by grooves 3 and by the separate tread bodies 5. Of the grades of rubber, either the harder grade 1 lies as a layer against the carcass and the more flexible grade 2 lies outside, so that it forms the tread surface 4, or alternatively the more flexible grade 1 lies as a layer against the carcass and the harder grade 2 lies outside and forms the tread surface 4. Some of the tread bodies are of a type 11, which in the direction of its height H1 is composed both of the first grade of rubber 1 of the said type on the carcass side and of the second grade of rubber 2 of said type on the tread surface. Some of the tread bodies are of a type 12 which in the direction of its height H2 is composed in the main of the second grade of rubber 2 on the tread surface. The height H1 from the bottom 7 of the grooves and up to the tyre periphery of the tread bodies in the first type is essentially greater than the height H2 of the tread bodies in the second type. <IMAGE>
