FIELD: automotive industry.
SUBSTANCE: invention relates to the automotive industry. Spike has a column-shaped housing section, a pin section located at one end of the housing section, and a flange section located at the other end of the housing section. Pin section is formed in the form of a mold having a longitudinal direction and a transverse direction. Pin section, the body section and the flange section in the orthographic projection satisfy the conditions 0 ≤ (SM/HM) ≤ 1.0 and 0 < (HM–SM)/FM < 0.7, where SM is the difference between the projected areas between the flange section and the hull section in the transverse direction of the stud section, the HM is the difference in the projected areas between the flange section and the body section in the longitudinal direction of the stud section of the stud which is perpendicular to the transverse direction of the pin section, and FM is the maximum cross-sectional area of the flange section perpendicular to the central axis of the stud.
EFFECT: increased reliability of fastening spikes in the tire.
