A stud for a studded tyre

Abstract

A stud (100) for improving grip of a tyre (200). The stud (100) comprises a body (120) comprising a base flange (140) and a second part (130), the second part (130) being joined to the base flange (140), and a pin (110) protruding from the second part (130) in the longitudinal direction (Sz) of the stud (100). The pin (110) comprises hard metal or ceramic. The base flange (140) has a first cross-section having a first area (A140). The pin (110) has a second cross-section having a second area (A110). A ratio (A140 / A110) of the first area (A140) to the second area (A110) is 6.5 to 21. Moreover, the pin (110) protrudes a first height (H110) from the second part (130) such that a ratio (A140 / H110) of the first area (A140) to the first height (H110) is 20 to 50 mm2 / mm.
