I've had my front fenders rolled and no issues with paint cracking. You just have to make sure you heat up the fender/paint with a heat gun before rolling. I also removed some of the fender liner underneath at 12 o'clock. Had no rubbing with 19x9.5 et25 275/30/19 PSS's. However I switched wheels and now have an et23 and rub slightly on sharp corners.
