Abstract
A pneumatic radial tire provides enhanced noise reduction and water releasing ability during driving by repetitious process of trapping air into the circumferential groove, formed on the tread as the air therein gets compressed and expanded before it gets released. The pneumatic tire includes a rib-lug tread pattern formed by circumferential grooves and several axial grooves at a slant angle relative to the circumferential grooves.
