235/60/15 on front of duster?

BBP disk brakes? No way. Not on a 15x8” with 4” of backspace. Not unless you adjust the ride height up so it looks like a 4x4.

SBP disks, maaaaaaybe. Still be super tight on the fender. Probably still have to move some stuff around to make that work.

hypothetically If I were to be looking at buying a set of these American racing wheels what do you think I could get away with on the front?

Available as a 17x7 and 17x8 (4 inch backspacing and 4.5 inch backspacing respectively)
Also max tire size?

I'm not racing by any means....just a spirited driver for the corners!
