Inventors:

Daniel Stephen Mathews - Jasper AL, US

International Classification:

B60C 11/01

US Classification:

15220916

Abstract:

A tire tread has a decoupling groove () with walls () that have a wavy shape in the radial direction with respect to the tire geometry, i.e. at least one axial deviation () along the depth of the decoupling groove (). An axial cut through the tire tread () divulges a wavy course of the decoupling groove (), where the two walls () have contours that complement each other. During a road contact of a respective tread section, the decoupling groove () closes, and a radially interlocking connection between the shoulder rib () and the decoupler rib () is made.Under load, the decoupler rib () functions like a part of the tread (), thus protecting the shoulder rib () from erosion wear.
