Title:
TREAD PROFILE WITH ASYMMETRIC CIRCUMFERENTIAL GROOVES
Document Type and Number:
WIPO Patent Application WO2007028442
Kind Code:
A9
Abstract:
Tread profile with circumferential channels (9, 10, 11), wherein the circumferential channel (9, 10, 11) is formed by a channel base (12), made to extend over the circumference of the vehicle tyre, and the channel walls (13, 14), made to extend radially outwards from the channel base (12) on both sides of the channel base and bounding the circumferential channel in the axial direction, wherein a first channel wall (13) is inclined at a first angle of intersection a in relation to the radial R in the tyre and a second channel wall (14) is inclined at a second angle of intersection ß in relation to the radial R in the tyre, and the transition (15) between the first channel wall (13) and the channel base (12) is formed with a first radius of curvature R1 and the transition (16) between the second channel wall (14) and the channel base (12) is formed with a second radius of curvature R2, wherein both the first angle of intersection a in relation to the radial R in the tyre is in each case made greater than the second angle of intersection ß in relation to the radial R in the tyre and the first radius of curvature R1 is in each case made greater than the second radius of curvature R2.
