<p>The tread has an anti-fracture and anti-wear studs (3) with external surface formed by lateral faces (30) facing side walls (11) of relief elements (1) e.g. circumferential orientation ribs. Each stud has two widen ends (EX) whose length is measured in circumferential direction, where the ends (EX) have axial faces at ends of the studs. The ends (EX) are localized at ends of unique external contact surface or localized at ends of contact surface radially near rolling surface in case of multiple contact surfaces.</p> |
