What kind of wrangler do u got? JK? TJ? YJ? Normaly u wont have a problem with it. I seen a lot of germans with selfmade flatfenders, so u normaly dont get problems with the Bushwackers. As long the tires dont stick out.
Little tip. Go to the inspection with the stock tires that dont stick out and get your licence. After that swap them and nobody cares when the tires stick out one ince.
