PNEUMATIC RUN-FLAT TIRE

摘要

A pneumatic run-flat tire has a bead configuration wherein the axially inner end is radially inward of the axially outer end of the bead. The side wall of the tire, from the bead region to the upper sidewall is reinforced to form a pillar support in the sidewall. The bead configuration and the pillar reinforcement enable the tire to lock itself onto a tire rim during low pressure operation and be self-supporting.
