I found it cheaper to buy new 15" alloy rims with 3.5" or less backspacing and go with 35x12.5R15 tires. 35's are cheaper than metric (315x75R16) and the price difference may even pay for the rims. The backspacing will help with rubbing and you save $200 on each future round of four tires. The one caveat is that 15" rims are not big enough for some aftermarket two piston calipers if they are in your future. Do the math and see if it's an option for you.Ehay is the biggest tire o ca put on rubicon 16" rims? Looking to go to 35's. Can i do it?
