Almost every all terrain is going to throw rocks. The spacing of ATs are perfect for pebbles, hybrid tires or mud terrains will throw less rocks
lol...I don't like following aggregate trucks, 18 wheelers, landscaping trailers etc...Picked up my first rock chip this weekend. I was following a SAS with the horrible Goodyears and - thwack! Instant rock chip. I will never follow another Bronco again, regardless of what tires they are running.
