Abstract
A pneumatic radial tire which is excellent in drainage and capable of reducing air-column-tube resonance sounds in circumferentially extending grooves to decrease noises. The pneumatic radial tire comprises a tread provided thereon with a groove extending circumferentially in the circumferential direction of the tire and a vibration buffer wall having essentially an identical cross-sectional shape provided near the sidewall of said circumferentially extending groove, wherein the height of the outside edge of the vibration buffer wall in the radial direction of the tire is lower than the height of the outside edge of the circumferentially extending groove in the radial direction of the tire.
