Stud of a tire

A tire stud comprising:

• a stainless-steel body comprising:
• a flange at a bottom end of the body, wherein the cross-sectional shape of the flange is non-circular for orientating a stud in an installation hole in a tire, and
• a blind hole extending from an opening at an upper surface of the body towards a lower surface of the body and terminating with a floor;
• and
• a spike which is installed in said hole such that:
• a lower surface of the spike is directed towards said floor, and
• an upper surface of the spike is directed away from said floor and is elevated with respect to the upper surface of the body,
• wherein:
• the cross-sectional shape of the hole is different from the cross-sectional shape of the spike at least at one of:
• the opening,
• the lower surface of the spike, and
• a depth between the opening and the lower surface of the spike,
• whereby only protrusions of the spike are attached to a side wall of the hole with friction joints where the cross-sectional shape of the hole is different from the cross-sectional shape of the spike;
• and
• wherein:
• at the opening, the cross-sectional shape of the opening is substantially similar to the cross-sectional shape of the spike at the opening, whereby the spike is attached to the side wall of the hole at the opening with a friction joint over substantially an entire circumference of the spike, and
• towards the floor, the cross-sectional shape of the hole is different from the cross-sectional shape of the spike at least at the lower surface of the spike, whereby only protrusions of the spike are attached to the side wall of the hole with friction joints at least at the lower surface of the spike.
