VEHICLE TIRE Russian patent published in 2019 - IPC B60C11/16 

FIELD: manufacturing technology.

SUBSTANCE: tire has tread profile and pins (1, 41), which are formed with stud with tip surrounding engagement edge (7, 47), has two lateral relative to axis of length part (22, 26), in which in each case only first tenons (47) of tread profile, and has length-shaped part (23, 24, 25) central relative to axis, which is formed between two lateral parts (22, 26) of length and in which solely second treads (1) of tread profile are formed. Tip of second tenon (1) with its contour profile of engaging edge (7) is formed symmetrically about axis, which is oriented so as to form an angle β relative to circumferential direction U, where 0°≤β≤20°. Tip of first tenon pin (41) with its contour profile of engaging edge (47) is formed symmetrically relative to first axis (m), which is oriented so as to form an angle α relative to axial direction A, where 0°≤α≤35°. Contour profile of engaging edge (47) of first tenon (41) has a shape different from that of the contour profile of engaging edge (7) of second stud (1). Tip of first tenon (41) with its contour profile of engaging edge (47) is formed in each case asymmetrically relative to the planes perpendicular to its first axis (m). Length (f) of axially formed projection of engaging edge (47) of first stud (41) in each case is greater than length (e) formed in axial direction A projection of engaging edge (7) of second tenon (1).

EFFECT: improved traction and braking characteristics of tire, as well as higher reliability of studs fixation in tire.
