A Festavan

getting conflicting information from different people on what will or will not work... Wheels with 5.25 backspace with tires that are 315/70/17. Will i get rubbing without spacers? And, if i have to run spacers, say, 1.25, how far will they stick outside the fenders? I have a 2.5 inch coil lift that I have setting in the box in the garage, trying to get all my pieces to my puzzle rounded up before I get started. Right now im running a 32 x10x17. tires are even with the fenders now. I have no problem with running spacers, i just didnt know where the tires were gonna end up.If the tires are even with the fenders now, wouldnt a 1.25 spacer put the tire out 1.25 inches? Any help with explaining this to me would be great.
