A pneumatic radial tire with contoured regions on the sidewalls.

摘要

The invention relates to a radial tire having a contoured area in EACH SIDE TIRE. OUTLINED AREA IMPROVES gusset DURATION AND REDUCES THE BREAKS OVER WIRES circumferential side. More particularly, the radial tire comprising (1) at least one belt circumferential reinforcement; (2) A PAIR OF SIDE WALLS extending from opposite edges of the strip BOOSTER TO THE EDGES OF TIRE FOR AND CONTAINING A FOLD SIMPLE reinforcing cord wound around each edge and having two terminal ends; (3) an internal cavity; (4) a contoured area, where that area OUTLINED (A) is located between said pleat CONSOLIDATION AND CABLE said internal cavity; (B) extends circumferentially around the tire axis; (C) lies in a region of each side wall DEFINED AREA GOING FROM THIS BAND BOOSTER TO LOSEXTREMOS TERMINALS said pleat SIMPLE CABLE REINFORCING AND (D) THE DISTANCE BETWEEN THE FOLD SIMPLE CABLE CONSOLIDATION AND said interior cavity IS GREATER THAN THE ZONE WHICH PART SITUA OUTLINED IN COMPARISON WITH THE DISTANCE BETWEEN THE fOLD CABLE SIMPLE CONSOLIDATION AND INTERIOR IN THE AREA SUCH CAVITY BELOW said reinforcement.
