I looked at some Kia Sprotage wheels at the junk yard last Sat. they are 6 1/2" wide, but have a about a 4 1/2" back spaceing & was looking to see if anyone has used them with 235/75 R15. I have a 98 Tracker 4dr. W/O a lift for now & would like to know if they will rub with that large if a offset on the wheel??
