Ive been on here trying to figure this out for about 5 hours now. Im looking at getting the cragar black steel rims and some trxus mts 33x12.5. I have a 2001 2500 CTD. Ive heard that the steel rims will not rub on the brake calipers...Does anyone know if this is true or not? Also i would like my tires to stick about 1.5- 2.5 inches out of the fender what backspacing would put me in that area with 12.5 tires and 16 or 15x8 rims? I would like to run the 15inch rims if possible i just do not want them to rub and dont feel like grinding my calipers down.
