Problems solved by technology

[0003] The use of common tire sipe in the pattern of the tire tread pattern is hampered by many disadvantages, the tire sipe having the shape of narrow grooves in the squares of the pattern causes the rigidity of the respective squares to be reduced, which results in the squares having Larger compliance, which causes disadvantages in tire control and drivin

Embodiment Construction

[0024] refer to figure 1 The plan view shown shows a pattern 10 having longitudinal grooves 15,16. Also provided is a longitudinal groove 17 oriented slightly obliquely to the direction of circumferential extension of the pattern 10 . The longitudinal grooves 16 do not extend continuously across the entire pattern 10, but are instead separated by sections of squares 26 in the pattern.

[0025] The respective longitudinal grooves 15, 16, 17 are separated by transverse grooves 18, 19, 20, 21, which are arranged vertically or slightly obliquely to the longitudinal grooves 15, 16, 17, the longitudinal grooves 15, 16, 17 and the transverse grooves 18, 19, 20, 21 define blocks 22, 23, 24, 25, 26 in the pattern pattern. In this arrangement the blocks 22, 26 formed on the inner and outer shoulders 11, 12 of the pattern 10 are larger, while the blocks 23, 24 formed in the central part of the pattern 10 are smaller. The square 25 which is likewise provided in the area of ​​the outer sho

Abstract

A vehicle tire comprising at least one circumferentially extending longitudinal groove (15, 16, 17) and transverse grooves (18, 19, 20, 21) radiating from said circumferentially extending longitudinal groove, so as to define blocks in a tread pattern ( 22, 23, 24, 25, 26) and includes arranging sipe (28, 30) in the pattern pattern, the pattern in the direction from the pattern surface (26a) to the pattern base (26b) By extension, for determining sufficient rigidity of the blocks it is provided according to the invention that at least one sipe (30) arranged in at least one block (26) forms a V-shape.
