Radialer Luftreifen mit besserer Haltbarkeit der Wulste.

摘要

In a pneumatic radial tire having a radial carcass (5), a carcass line in radial section of the tire at a self-posture under an internal pressure corresponding to 5% of normal internal pressure and no load has at least two inflection points between positions A and B where A is a position intersecting with a vertical line drawn from a rim base line RL at a width position of a normal rim (7) and B is a position corresponding to a maximum width of the carcass, and the turnup end is located in a region defined by two parallel lines Q1 and Q2 parallely drawn in perpendicular to a straight line L defined by connecting two inflection points near to the position A to each other at a distance d of not more than 10 mm from a point P most separated from the straight line L and located on the carcass line.
