Pneumatic radial tire with water-splash control rib

Abstract

The present invention relates to a pneumatic radial tire, and more particularly, to a pneumatic radial tire with water-splash control rib, wherein by optimizing the profile of the ring-shaped water-splash control rib on the sidewall along the circumference of the tire, the water-splash control, the increase in heat radiation, and the durability of the tire will be improved. A preferred aspect of the present pneumatic radial tire with water-splash control rib is that the layer of belts deposited under the tread and a ring-shaped water-splash control rib (100) formed on the sidewall, wherein the upper profile of the rib is positioned above the continuation line (Ca) which extends the average profile of the outmost layer of belts which is divided in to upper and lower profile. With such a structure, the present invention will increase the rigidity of the rib, decrease the size and the weight of the rib without lowering the efficiency of the water-splash control, and prevent loss of heat radiation and durability and at the same time, improve safety while driving compared to conventional water-splash control tires.
