Problems solved by technology

However, these fine cuts lack the receiving capacity to quickly receive water at the tire surface
[0004] Even in new tires where the tread is formed with a large tread depth, these known fine incisions protruding very deeply into the tread may reduce to an undesired extent the dryness desired for good drying properties. stiffness

Embodiment Construction

[0028] figure 1 and figure 2 Shows the tread pattern of a vehicle pneumatic tire of a passenger car (Pkw), which are arranged next to each other in the axial direction A of the vehicle pneumatic tire, correspondingly extending over the entire circumference of the vehicle pneumatic tire and in the circumferential direction U A plurality of upwardly oriented radially raised ribs 1 , 2 , 3 , 4 and 5 are arranged next to each other.

[0029] Here, the tread rib 1 constitutes a circumferential rib formed at the left shoulder of the tread. Here, the tread ribs 5 are formed in figure 1 The circumferential rib that forms at the right shoulder of the tread. These ribs 2 , 3 and 4 are arranged between the two shoulder ribs 1 and 5 in the axial direction A of the vehicle pneumatic tire. Here, the rib 1 is a rib directed toward the outer side OU of the vehicle in a state of being mounted on the vehicle. The rib 5 is a rib directed inward IN.

[0030] These ribs 1 and 2 are spaced a...

Abstract

Disclosed are pneumatic vehicle tyres having a profiled tyre tread comprising profiled ribs (1, 2, 3, 4, 5) that are spaced apart from each other by circumferential grooves (6, 7, 8, 9) and that extend over the circumference of the tyre, which profiled ribs are delimited by a radially outer surface that forms the ground contact surface and are formed with a width B measured in an axial direction A of the tyre in the radially outer surface, wherein: surface channels (12) are formed in the radially outer surface of at least one profiled rib (4), said channels being distributed over the circumference of the tyre, with a width b1 measured along their main extent in the radial outer surface, where b1<= 3mm, and with a depth t1 measured in the radial direction R, where 1mm < t1 < 2mm; spherical-shaped recesses (13) are formed in the radially outer surface, said recesses being distributed over the circumference of the tyre inside the center extension section, being measured in the axial direction A of the profiled rib (4) and having a diameter D formed in the radial outer surface, where b1< D < 5mm, and a depth t2, where t1 < t2 < 3mm; and wherein a channel (12) runs into each recess (13).

Description

technical field [0001] The present invention relates to a vehicle pneumatic tire having a molded tread having a plurality of ribs extending on the circumference of the tire spaced apart from each other by a plurality of circumferential grooves, the ribs extending radially Outwardly in direction R is bounded by a radially outer surface forming the ground contacting surface and formed to have a width B measured in the axial direction A of the tyre, in the radially outer surface. Background technique [0002] It is desirable in such vehicle pneumatic tires that the radially outer surface be formed as flat as possible in order to obtain good drying properties and good noise behavior. The known tread grooves or free cuts influence the stiffness and thus the dry properties, such as traction, braking or handling on dry roads. In addition, they are also prone to undesired noise. On the other hand, such grooves and ribs without fine cuts are less suitable for receiving and expellin...
