Abstract

This invention relates to a tire having a directional tread pattern with a first shoulder region, a central region, and a second shoulder region, the tire having a plurality of studs in the first shoulder region, the second shoulder region, and the central region; wherein at least some of the plurality of the studs in the central shoulder region extends longitudinally into the tread member in a direction inclined relative to the normal of the outer surface of the tread member by an angle in the circumferential direction of the tire, and wherein at least some of the studs in the first shoulder region and the second shoulder region extend longitudinally into the tread in a direction inclined relative to the normal of the outer surface of the tread in a direction different from the studs in the central region.

Dependent claims

A tire comprising a tread member having a directional tread pattern and which is divided in the tire width direction between a central region placed between a first shoulder region and a second shoulder region, the tire comprising a first plurality of studs installed in the first shoulder region and a second plurality of studs installed in the second shoulder region and a third plurality of studs installed in the central region;

each of the studs comprising a body and a stud pin with a tip end protruding out of the body, the body being at least partially embedded in the tread member;
wherein at least a part of the third plurality of the studs extends longitudinally into the tread member in a direction inclined relative to the normal of the outer surface of the tread member by a first angle α in the circumferential direction of the tire;
and wherein at least a part of the first and second plurality of studs extends longitudinally into the tread member in a direction inclined relative to the normal of the outer surface of the tread member in a direction being different than the third plurality of the studs.

each of the studs comprising a body and a stud pin with a tip end protruding out of the body, the body being at least partially embedded in the tread member wherein at least a part of the third plurality of the studs extends longitudinally into the tread member in a direction inclined relative to the normal of the outer surface of the tread member by a first angle α in the circumferential direction of the tire, wherein the first angle α is within the range of 5° to 40°, and wherein the tip end size of the third plurality of studs is smaller than the tip end size of the first and second plurality of studs, wherein the size of a tip end is defined by the maximum cross-section of said tip end.
