Abstract
A pneumatic radial ply tire with an aspect ratio of less than 50 has a ground contacting tread radially outward of a circumferential belt structure which in turn is radially ourtward of a carcass structure. The carcass structure has a pair of bead areas that include a bead foot compatible with a conventionally-shaped wheel rim having flanges with laterally extending portions. The carcass structure has a cord-reinforced elastomeric ply layer extend laterally between the two bead areas and radially inward of the belt structure. The tread area is directly connected to the bead areas without a sidewall. Rim flange protectors comprising a continuous circumferential elastomeric projection extend laterally outward from each bead/tread area and thereby radially outward of the rim flanges.
