So I got a call from one of my after market reps today asking about tire sizes for the pioneer 500. He was telling me a lot of dealers are saying 26" tires are a no go due to scrubbing. I have sti black diamonds in 27" and have not noticed any scrubbing but I told him I would check into it. When I got home yesterday while installing boot guards and skid plates I checked it out. On the front wheel well the corner or the frame sticks out a little past the wheel well and at full turn my tire are very close to the frame. With a little suspension compression might even touch. Nothing major but figured i would give you guys a heads up invade any one is planning larger tires. They will fit just gonna have to remember that they will rub at full turn.
