what do I do to make them fit? The reason that I am going to a wider rim is because I am going to a larger(315x75x16) tire that requires a wider rim. These rims are going on a 2001 Chevrolet Silverado 4x4 Regular Cab. I am going to be using a 3 inch body lift. What am I going to need to make these rims fit safely, if I need anything to make them fit? The backspace on the new rims are 3 5/8". Any ideas?
