Selection of Tires for Over-the-Road Vehicles

Two conditions must be fulfilled in selecting truck tires for over-the-road service: tires must be adequate for the service, and tire costs must be minimal.

Four types of truck tires available for over-the-road service are: highway tires -- usable for all highway service except where extra traction is required; “extra tread” highway tires -- usable to obtain higher tread miles when tire temperature is not excessive; “cross lug” highway tires --usable on drive wheels to obtain higher tread miles and extra traction; and special service mud-snow tires -- usable on drive wheels to provide added traction in mud or snow or other limited off-the-road service.
