RUN FLAT TYRES,INSERTS AND WHEELS

摘要

The insert 14 of closed cell elastomeric material has its inner surface formed of a harder material or bonded to a band 24 of metal, plastics or carbon fibre, which serves to combat centrifugal forces pulling the insert from the wheel during normal running of the wheel and to prevent circumferential slippage of the insert. The insert may be provided with cuts extending radially inwardly from its outer surface and may have axially extending formations to engage in corresponding channels in the wheel. The insert may be covered by a flexible air impermeable membrane.
