Pneumatic tire which changed shape of lymph range tow part

摘要

The present invention improves the shape of the tow (6 ') portion of the lymph range of the tire. The V-shaped notch groove (7) is installed near the tow (6') portion of the lymph range to inflate air into the tire. By changing the shape so that the groove absorbs the outer flexion of the seed beads 2 and 3 so that the lymphrange is completely in contact with the rim 4 of the wheel, the rim of the lymph 5 and the rim of the wheel even after air injection. (4) It is a very useful design that prevents accidents caused by air leakage of tires, and also saves rubber raw materials by reducing the weight of tires.
