Is there a new design? I went with the stamped iron hangers with sheet rubber flaps.
The fronts are worthwhile, very nice splatter & mud flinging deflectors plus no rub marks on them so far from oversize 245 tires either.
On the rears, if it gets the chance, back up against a curb, into parking place or turning around etc., will pinch flap between tire and curb and tear the rubber cleanly across the rivet points; to drill out and replace the rivets with the now shortened flap will raise it to miss a few curbs in the future but a tall one will catch it again. When the flap gets torn it is noiseless, just leaves the piece laying behind as one drives away. Guess how I know.
