Yes I run 12 inch rims also.I first had 29x15x12 Hoosiers and had minimal rubbing.After frying those slicks over a 2 yr period with a couple 100 burnouts,I steeped down to a 11.5 slick.You have to take into consideration with the buldge factor.With the minitub your limited to 14 inches per side.Keep up the great work...looking good!
