When I upgrade to 37s I am thinking of going with a 17x9 with either 3.5" or a 4.5" with a 37x13.5x17. Does anyone have any experience running either a 17x9 3.5" backspacing or 4.5" backspacing with a 37x13.5 tire?
I'm running a 17x9, -12mm offset, which should work out to a 4" backspace. Puts the 37x12.5x17 KO2 flush with the edge of the flares. Half inch either way would be fine.
