I searched for this already but couldn't find the answer. Have a stock height bronco with 15x10 wheels. 33x12.5x15 tires. Found some 15x12 Weld rims for sale. Will these fit? or does that width require a lift?
If they have the proper lug pattern, they will fit (5x5.5). Depending on the backspacing, you could get some rubbing on the radius arms or on the fenders/bumpers. Fenders could be fixed with a little bit of trimming. That being said, 12 inch wide wheels with 12.5 inch tires looks bad (I had that set up for a while and hated the way it looked) and does not do much for your ability to air down offroad (easier to seperate the bead).
They will fit and a lift wouldnt help anything. Depending on the offset and backspacing, you might get rub on the radius arms with them but a lift wouldnt fix that.
Why are you looking at 12" wide? You like the style? If its for size, just because the tire is 12.5 wide doesnt mean you need a rim super close. You could run 7" or a 8" comfortably if you wanted to. Getting a 12" wide wheel for a 12.5" tire means you'll have a much higher chance of losing a bead
EDIT: posted at the same time as Shane and it looks like the same information haha
