Changing tires (up to 285 pounds and 48 inches in diameter) on a truck and most tractors is a one-man job with the Clever Lever Tire/Wheel Caddy. The arms of the "U"-shaped device are fitted with side-mounted rollers that allow the tire to be rotated to line up studs. To use, one simply rolls the tool under the tire, then lifts and pulls the tire out.
