If i mounted a 33x12.5 on a factory bronco 15x7.5 rim and used it for a spare while i have 15x10's everywhere else would it hurt the truck to run with the 33 on 15x7.5 in the event of a flat?

I wouldn't think so. It probably would if it was a smaller diameter tire even then put it on the front and run it till you get to an alignment shop.

You could always get a 33/9.5 for a spare...they fit real good on the factory wheels...
