17" versus 14" tires

Darts and demons can clear a tall tire on the front than a duster..I tried my dads 17x8 5.5bs with 255/45r17 on my duster..They will only clear the bottom of the front fender by 1/8 or less…Is anyone running a 225/45r17 on the front ?
good to know, I was looking at 225 or 235 45R17's as an option for my duster...the 235 should give an additional 3/8" clearance, the 225 about 1/2" additional clearance by the math just on height alone
