Abstract
A vehicle tyre(1) has cuts(3) in the tread which in plan view have a zig-zag or wave form along a direction(E) running roughly in the axial direction(A) of the tyre. When viewed tangential to the tread and perpendicular to the direction(E) the cuts(3) display peaks(4) and troughs(5) inclined to a tyre radius and extending from the cut base(G) to the tyre surface. In the same view all peaks(4) and troughs(5) are curved in the same direction, all peaks having equal curvature and all troughs having equal curvature. The angle of peaks(4) and troughs(5) to a radius at the tyre surface is greater than the corresponding angle at the base of each cut(3). Lamellae for installation in a tyre mould used to produce a tyre with the claimed tread features have a zig-zag or wave profile on the side facing the tyre and the profile along the lamellae length forms peaks and troughs with corresponding geometry to the described cuts(3) except that the lamellae have a male instead of a female form. Also claimed is a tyre vulcanising mould with the said lamellae which are positioned with their depth approximately in the radial direction of the mould.
