possibility of “ <italic>Spare Tire Elimination</italic> ” by use of Dual Compartment Tires

SPARE TIRE elimination is a problem that has defied tire engineers for years. Because the space it occupies is wanted for other purposes, increased efforts are being applied to the search for a solution.

This paper describes one approach — the dual compartment tire. This is made up of two tires, one inside the other, both of which are inflated at all tiines. If the outer tire is punctured, the inner tire supports the car until it reaches a service station.

According to the author, tests indicate that this solution holds promise of eliminating the spare — if the cost can be lowered.*
