Tire with deep tread groove comprising an inextensible ring in said groove

摘要

A tire (10, 66, 70, 86) is manufactured on standard tire building equipment and cured in standard curing presses. The tire tread (12) has at least one deep circumferentially extending groove (48, 96). Within the groove (48,96) is a separately assembled ring (50). The ring (50) may be fitted into the deep groove (48, 96) after vulcanization of the tire (10, 66, 70, 86). For very wide tires, two grooves (48, 96) with two external rings (50) may be used or more than two grooves and rings, depending upon the tire's width.
