Firestone Special Tire Features.
The Firestone demountable rim may be used in connection with clincher or quick-detachable tires. It consists of three parts; channel-rim, locking-ring and demountable portion containing the tire. It has no narrow wedge shapes and no sharp angles, so that its parts cannot rust together and make the rim difficult to manipulate. This is the same equipment as was used in connection with Firestone tires by the locomobile in winning the Fairmount Park race at Philadelphia, an all-rubber non-skid tread formed by the raised oblique lettering, Firestone Non-Skid, arranged in rows across the tread-surface of the tie, which is claimed gives it better antiskid properties, and long-lived effectiveness.
