I inquired about the super single in my build thread a while back...had access to two rims. Thought it would look pretty cool with a bigass tire out back, tubbed look. It's legal according to our tire guy and safety and compliance.
....as said above, huge cost for a road side repair. $1000 a tire from a tire shop here in Ontario, probably $1200 from a mobile guy...that's if you didn't roll the edge of the rim over from the weight of the bus/coach.
...you also have two rolling spares to get to out of a jam, if you got a front flat you could steel one of the rears to hobble yourself to safety. Hydroplaning could be a issue as well.
This guy showed up at the beer store on Sunday with his pick up, he removed the front drive, and fifth wheel, installed super singles, put fuel tanks from a Pete, turned the bunk into a tool box. The bunk and box are removable, he said he has an 8.3 cummins with a 13 speed direct and runnin' low 15's at St. Thomas and Grand Bend drag strips.
