question 1: i want to run a 12.50 tire(dont know wat size yet). can i run a larger tire on a smaller rim or do i also have 2 buy a 12.50 wheel?

question 2: wat is the max size tire can i run with a 4 inch lift w/o rubbing on the fenders or w/o having 2 trim the metal fender flares?

question 3: can i run any 12.50 tire stock w/o rubbing?
