So I just put a 6" lift on my f350 and I want to put 37" tires on. But the problem is that if I turn to far to one side the tire will rub on the leaf springs. So I'm hoping a rim with a enough offset would solve this problem. I just need to know the minimum offset I'd need to clear the springs with 37" tires. I'm kinda on a limited budget so $1,500 isn't an option really. Anyway I currently don't have 37" tires or rims to put on, but I'm hoping -25 offset or 4" backspace on a rim with a width of 9" should clear for 37x13.50 tires? Or maybe 37x12.50. With an 16.5" rim or 18" rim. Preferably 18" but I can find cheaper tires for 16.50 ya know.

 

Any information on a minimum offset or backspace that'll make it work would be nice.
