I saw your thread and that's where i gathered that 30.5" will fit, just not sure if that's the max on diameter or not.I you have not checked my thread in this forum please do so. It's entitled "God, I Hope This works". Regardless, wheel offset and tire width also make a difference. The greatest concern is the front wheel wells when the steering wheel is turned full over. Check the front and rear of the wheel wells for clearence.
