Abstract
The present invention relates to tire studs, each tire stud comprising a stud body and a pin, wherein at least a portion of the pin has a particular polygonal cross section. The present invention further relates to a pneumatic tire comprising said tire stud. Such tire studs are of particular value for use on winter, snow and/or ice tires.
Claims19
A tire stud comprising
- a stud body;
- a pin comprising a first portion P1 and a second portion P2, P1 being adjacent to P2 in a direction along the central axis (z) of the pin, P1 projecting out of the stud body and P2 being inserted in the stud body;
- wherein P1 has a polygonal cross section in a plane perpendicular to the central axis (z), said cross section being symmetrical with regard to an axis (y) within the plane;
- wherein the polygonal cross section has six sides being a first side C1, a second side C2, a third side C3, a fourth side C4, a fifth side C5 and a sixth side C6,
- wherein C1 is adjacent to C2 and the intersection of C1 and C2 is a point S(12) located on the axis (y), C1 and C2 form an angle a2 on the outer surface of the pin, wherein 90°<a2<170°.
