225/60-15 fit perfectly (front and rear) with 7" wheels with 4.5" rear spacing. I've been running that combination for years with no problems. Anyone with rubbing issues with a 225 tire has wheels with the wrong backspacing.
Most probably try it on a 4.25 bs wheel (like mine are) and they will rub. To begin with I had mine set a tad low and at full lock it would barely rub. It happens when you go from 32" to 26" in height up front.
