PNEUMATIC VEHICLE TYRE

摘要

A pneumatic vehicle tyre, in particular for use under winter driving conditions, wherein in each case two block row pairs (2, 3) run in each tread half and are separated from one another by first circumferential grooves (4, 5) which run in the circumferential direction and are formed in the maximum profile depth, wherein second circumferential grooves (10, 11) which are made narrower than the first circumferential grooves (4, 5) and extend as far as a depth which is lower than the maximum profile depth run between the block rows (6, 7, 8, 9) of each block row pair, wherein all the transverse grooves (6b, 7b, 8b, 9b) have a depth which changes over their extent such that their groove base, considered in cross section, runs along a curve which is slightly curved in an S shape, wherein the depth of the transverse grooves (6b, 7b, 8b, 9b) at their junction points with the first circumferential grooves (4, 5) or at their ends on the outer shoulders (20) of the tyre corresponds at least essentially to the maximum profile depth, and wherein the depth of the transverse grooves (6b, 7b, 8b, 9b) at the junction regions with the second circumferential grooves (10, 11) corresponds to the depth of these circumferential grooves (10, 11).
