I was running M/T sportsman pro's that were 29x12.5x15LT but I had go go a little more narrow and taller to get this wide of a tire in the M/T SR radials.
They have weird size choices and I really did not want to go that tall but I wanted the radials and this was the best I could do and the widest I could go given the choices they had.
Ultimately I would have liked a 28 or 29x13.5x15 but now I'm dreaming.
I really like the way it handles now and I no longer hydroplane in the rain.
Mini tubbed, springs relocated 3" but the rear is stock size, just have 7.5" backspace that gives a shallow well to the wheel.
I would love to swap for a narrowed rear to get a deeper dish wheel in there.
