High compression beads for tires.

摘要

A tubeless pneumatic tire (10) is mountable upon a standard rim and has improved roll-off characteristics in the event the tire is operated at a pressure lower than the design inflation pressure. The tire has a rim interference in the range of 0.4 to 0.6, a conical surface (36) connecting the radially inner surface (28) and axially outer surface (32) of each bead portion, and a sealing lip (38) extending axially and radially inwardly from the radially inner surface of the bead portion.
