Abstract
A pneumatic radial tire having tread, outer shoulder, and sidewall portions of elastomeric material over a radial carcass. The tread and outer shoulder portions comprise similar circumferentially overlapping patterns of lugs and grooves. The majority of the edges of the lugs are disposed at an angle of approximately 60.degree. with respect to the equator of the tire. The tire has a groove adjacent each outer shoulder portion and bounded by radially displaced adjacent outer shoulder lug portions and by radially displaced adjacent sidewall lugs. Each such groove adjacent each outer shoulder portion has relatively long sections extending circumferentially of the tire. The tire has a tread having at all points of the tread lug contact area substantially identical surface pressures and has high road holding ability on dry as well as on wet or snow-covered roads. The tire is also effective in draining a substantial volume of water or waterlogged snow and provides improved travel confort.
