Abstract
A tread design for a pneumatic tire of radial construction for high-speed vehicles is provided. The tread design comprises profiled elements that are steeply oriented in the circumferential direction at an angle to the equatorial plane of the tire and are arranged in the shape of V's. The profiled elements extend in a continuous manner from a central portion of the tread into shoulder regions of the tire and are angled-off at a bend region in these shoulder regions. Respective continuous, inclined grooves that proceed from the central portion of the tread to the shoulder regions are formed between the profile elements. Respective fork-shaped elements are provided in the shoulder regions in the vicinity of ends of the profiled elements remote from the central portion of the tread, with each fork-shaped element being provided with at least one short groove that opens into the shoulder region away from the bend region thereof.
