SCHLAUCHLOSER REIFEN MIT STEILSCHULTER-WULSTTEILEN

摘要

A tire and rim assembly including a flanged rim and a tubeless tire with 15 DEG taper bead parts. The tire includes a carcass having a main body portion extending from a tread part through sidewall parts to the bead parts and turned up portions each turned up around a bead core of the bead part from axially inside to outside. In each bead part, a first reinforcement layer of steel cords and a second reinforcement layer of steel cords are provided. The first reinforcement layer has an inside part extending along the inside surface in the axial direction of the body portion, and an outside part contiguous to the inside part and extending along the outside surface in the axial direction of the turned up portion. The second reinforcement layer extends from a radial position substantially level with the bead heel end and is interposed between the inside part and the main body portion along the main body portion so as to form an overlapping portion with the inside part. Further, the width of the overlapping portion is in a range of 0.3 to 0.5 times the height H3 of the upper end of the second reinforcement layer, the height H1 of the upper end of the turned up portion is in a range of 2.7 to 4.0 times the flange height HF of the rim flange, the height H2 of the upper end of the inside part is in a range of 1.5 to 2.4 times the flange height HF, and the ratio H3/H1 is in a range of 1.2 to 1.6.
