Looking to add some lift to your Ford Bronco II and trying to choose a tire size, or do you want to know how much lit you need to clear a specific tire size? Hopefully this will help:

 

This Bronco II is not lifted, but still managed to fit 31×10.5R15 BFGoodrich Mud Terrain TA KM2 tires on Pro Comp #7031 15×8 alloy wheels with a 3.75 back space

This Bronco II has a 4-inch Skyjacker suspension lift with 33×12.50×15 Interco TRXUS MT tires
