Continental Tire North America Inc. is looking at a possible 2005 release date for two super single drive and trailer tires under development, the company said.
The tires, in size 445/50R22.5, include the HDL drive tire with a 25/32-inch tread depth and the HTL trailer tire with a 13/32-inch tread depth.
Conti displayed prototypes of the tires at its Uvalde Proving Grounds during its ``Test Out West'' introduction the weeks of Feb. 24 and March 3 of seven new Continental-brand medium truck tires designed for the North American market.
Use of super single tires, in place of tandem wheels on trucks, could save an estimated 900-1,000 pounds per trip on trucks using steel wheels and about 600 pounds per trip for trucks with aluminum wheels, said Curtis Decker, product development engineer for Conti's commercial group in Mt. Vernon, Ill. Liquid bulk transport trucks ``would be a perfect application for this tire,'' he added.
Mr. Decker said several issues, including the dissipation of heat, still must be addressed with these tires because of their wide footprint and low profile.
