Vehicle tire with a tread rubber profile

Vehicle tire having a tread rubber profile which includes grooves running in a circumferential direction, diagonal grooves, two shoulder block rows and a pair of center block rows arranged between the two shoulder block rows. Each of the two shoulder block rows and each of the pair of center block rows include blocks. Each of the blocks include a plurality of fine indents running generally parallel to one another. The tread rubber profile has a road contact area defined by a width Y and a center profile area defined by a width X, whereby the width Y at least partially encompasses the two shoulder block rows and whereby the width X is generally defined by axial outer edges of the pair of center block rows. A ratio of the width Y to the width X is between approximately 1−(D R −100)×1.5 and approximately 1−(D R −100)×5, whereby D R represents a diameter of a rim to which the vehicle tire can be connected. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Pneumatic vehicle tyre with micro sipes

Pneumatic vehicle tyre with a tread rubber, which is divided by circumferential grooves (1, 1', 1'', 1'''), by transverse grooves (4, 4', 4') and optionally further channels (10, 10', 10'') into profile positives (3, 3', 3', 7, 8, 8'), which are at least partly provided with a multiplicity of sipes with a width of up to 0.8 mm, which preferably run parallel to one another within the profile positives (3, 3', 3', 7, 8, 8'), and also has profile positives (3, 3', 3', 7, 8, 8') which are provided with micro sipes (12, 12a, 12', 12', 16, 16', 17, 19, 19', 26, 31) which have a width of from 0.1 mm to 0.4 mm, in particular up to 0.3 mm.
