Nope, those rear fenders are Flared. (could be rolled too but you wouldn't want to mislead people)

Those are flared fenders, not rolled fenders as in this discussion. Rolled fenders are rolling the lip inside the wheel well up, so it doesn't interfere with the tire. Rolling the fender lips is unnoticeable unless you look up into the wheel well, you CANNOT tell it from outside the car (unless you screw something up badly). Just FYI, and so noone is scared off by thinking that rolling your fenders alters the outside appearance of your vehicle.
