Hello all, I own a 2006 5030 with the R4 industrial tires. Dealer is going to order new R1 tires and wheels for me. I need more traction all year, and in snow, ice I need chains on the rear. (Previously owned Ford 2000 with rear chains). Will the 13.6x28 size leave enough clearance between the underside of top of fender and tire for chains? I know there will be adequate clearance on the side of the tire and fender. Thanks! RonB
