<p>A pneumatic tyre having lateral tread grooves extending parallel or aslant to the axial direction of the tyre, wherein the lateral tread grooves (G) are provided with a bridge (B) between the opposed groove sidewalls (GW), the bridge (b) being above and apart from the groove base (GB) and connecting the said groove sidewalls GW to each other, whereby the movement of the groove sidewalls GW and the deformation when contacting and leaving the ground is reduced to prevent uneven wear such as heel and toe wear without deteriorating the braking performance.</p> |
