What was the back spacing on your 17 inch rim you tried the 325 /45 on ?
No worries, I'm just pondering backspacing lol.
I'm running 15x10 billet specialties with 6.5 BS. MM brake lines, MM rear tie rods, low profile IRS bolts, and the normal grinding on the IRS knuckle. Otherwise they fit fine........and the 295/55/15's don't ever scrub unless I absolutely bottom out the IRS
