Abstract: A pneumatic radial ply tire has an aspect ratio in the range of 0.2 to 0.8, preferably 0.5 to 0.8. The tire has a pair of parallel annular beads, at least two radial carcass plies, at least one radial carcass ply having a pair of turnups being wrapped about said beads. The tire has a belt structure disposed radially outwardly of said radial carcass plies in a crown area of the tire. The belt structure has a width defined as the distance between edges of the belt structure. The tread is disposed radially outward of said belt structure and a sidewall is disposed between the tread and the beads. Each sidewall has a gumstrip interposed between two radial carcass plies extending from below the belt structure radially inward to a radially inner end located at or above the maximum section width of the tire.
