So can a guy put 26-9-12's on any 12" rim? I have 25-8-12 on ththe front and 25-10-12 on the rear. Found some Sedona tires (26-9-12). Will they work on my 12" rims, front and back?I believe that a change in wheel size, say from a 12" to a 14", does nothing to improve your ground clearance. A 26x9x12 and a 26x9x14 tire will both result in the same height since it is the tire sidewall height that is modified to maintain the overall 26" tire height. In other words the 26x9x14 will have less sidewall height than the equivalent 12" tire - if I understand correctly.
