FIELD: machine building.SUBSTANCE: invention relates to tire, preventing overheating in motion. Tire comprises tread with groove passing in circumferential direction, plurality of ledges placed at groove bottom, each running from one side wall to opposite. On one of side walls a recess is made, guiding one-way air flow through grouser groove in circumferential direction. In tire surface projection recess is triangular and located opposite to grouser groove, including output into groove. Recess top is located in grouser groove extension direction and shifted from its center, positioned on such grouser groove central line, perpendicular to said grouser groove extension direction. At that, ledges are arranged in groove with preset intervals.EFFECT: achieved tread in motion overheating prevention.6 cl, 1 tbl, 20 dwg |
