You will need an alignment, and you'll have some issues with speed bumps and the like, but the tires should probably be ok. You may want an adjustable panhard though in the rear, I know with rubber/stock panhard I could corner hard enough to get the tire to rub the inside and the rear of the car would actually kick out, strips the paint on the inside of the tire well showing where it rubbed. I've got 255x50-16s in the rear.
