Safety insert for tubeless tyre - consists of porous covered foam rubber ring to reduce rate of deflation on blowout

摘要

The safety insert for a tubeless tyre comprises a plastics ring of foam-like texture covered with a special porous skin. This regulates the escape of the compressed air to the tyre in the event of a blowout and enables the vehicle to be stopped safely. The porous holes are funnel shaped, wider on the outside. The foam is braced by a reinforcing insert and the ring can be fitted over any wheel rim. The vehicle can also be driven slowly on the ring.
