What would be the benefits of O.D. going to super singles on tractors ? I talked to a O/O today,he had put super singles on his new Volvo screw.Said they rode great,made the rear about 400lbs lighter.The tires run over 600 bucks a piece and he had a 800 number for repairs.I just don't think they would work in some of O.D.'s yards if they're as bad as I've been told.I'm sure the nickels and dimes would be figured out and there would be testing before O.D. jumped on them.
