Fold-up Spare Tire
TAKING up a space of only about 6 x 10 x 14 inches when folded, this collapsible spare tire is just about glove-compartment size. Developer and manufacturer is The Gates Rubber Company, Dept. SM, 999 S. Broadway, Denver 17, Colo. The compact spare is quickly slipped over a wheel rim after the damaged tire has been removed, and inflated with a carbon dioxide cylinder. With a tread life of about 1000 miles, the tire can be easily deflated, removed from the wheel and refolded for future use. The Fold-Away tire will soon be available through tire dealers for approximately 75% of the cost of a standard 100 level tire; tire puller and carbon dioxide cylinder will be included in kit later.
