Embodiment Construction

[0010] figure 1 The tread shown in is intended for vehicle pneumatic tires for passenger cars of radial construction, in particular for use in winter driving conditions, and preferably has an outer contour with a tread radius of 300 mm to 400 mm. However, the invention is not limited to winter tyres, but can also be applied to summer tyres. Furthermore, the exemplary tread has a pattern that is implemented in a direction-dependent manner. The invention is not limited to this tread pattern, but can be applied to all kinds of tread patterns.

[0011] exist figure 1 A-A is used to describe the equator of the tire, whereby the tread of the vehicle pneumatic tire is divided into two halves. This tread has two shoulder block rows 1, the blocks 2 of which are separated from each other by a plurality of transverse grooves 3, which are substantially in the transverse direction of the tread or in the order of 5° to 7° It extends obliquely in the transverse direction of the tread und...

Abstract

Pneumatic vehicle tyre, in particle a tyre for passenger cars having a tread which is divided by grooves, channels (3, 4) and the like into profile positives, for example profile blocks (2, 5, 7) and which has a smaller profile depth in its central region than in the lateral regions. Given division of each tread half - between the tyre equator (A-A) and the tread edge (L) bounding the ground contact patch width (B) - into three circumferential sections (S1, S2, S3), the first circumferential section (S1) of which, which runs adjacent to the tyre equator (A-A) having a width of 15 % of the ground contact patch width (B) and the two further circumferential sections (S2, S3) each having a width of 17.5 % of the ground contact patch width (B), in each case a relatively small portion of the positive face of the tread half is located in the first and in the second circumferential section (S1, S2) than in the third circumferential section (S3) and the circumferential rigidity is in each case smaller in the first and in the second circumferential section (S1, S2) than in the third circumferential section (S3).

Description

technical field [0001] The present invention relates to a pneumatic tire for vehicles, in particular a tire for passenger cars having a tread which is divided into profilpositive by means of a plurality of grooves, grooves and the like, e.g. a plurality of tread blocks and have a smaller tread depth in the central region thereof than in the lateral regions. Various embodiments of such pneumatic tires for vehicles are known. Background technique [0002] For example, tread patterns are known from US 2002 / 069949 A1 and WO 2011 / 060900 A1 which consist of rows of blocks and are provided for winter tires. It is important in these documents that the circumferential rigidity of the tread blocks be influenced in a targeted manner by the arrangement and implementation of the incisions. [0003] When developing pneumatic tires for vehicles, the wear performance is usually optimized in a number of steps in an iterative process. It is known that the wear behavior of a tread is influe...
