TIRE

WIPO Patent Application WO/2024/095526

A1

This tire comprises a lug groove that is formed as an opening in a ground-contacting during straight-ahead-travel edge. A first inclination angle θ1 that a first straight line forms with the tire width direction on the acute-angle side is larger than a second inclination angle θ2 that a second straight line forms with the tire width direction on the acute-angle side, the first straight line linking a first point that is positioned on a ground-contacting during straight-ahead-travel line at the tire-width-direction position of the tire-width-direction inner end of the lug groove and a second point that is positioned on the ground-contacting during straight-ahead-travel line at the ground-contacting during straight-ahead-travel edge, and the second straight line linking a third point that is the tire-width inner end of the groove-width central line of the lug groove and a fourth point that is positioned on the groove-width central line of the lug groove at the ground-contacting during straight-ahead-travel edge. The lug groove has, at least over an area extending from the tire-width-direction inner end of the lug groove to the ground-contacting during straight-ahead-travel edge, a groove width that gradually increases toward the outside in the tire width direction without becoming constant.
