i dont know what really is going on but if you were to look at the tire, the dirt from the roads is only in certain spots on the tire, and he did mention about going to check the alignment, thats if he needs to, but i told him its just that they are new tires, since he hasnt had them very long and its been sitting due to a broken shift cable (300 bucks to replace) i told him its just like a lifted truck you hear more tire then anything else even in the cab, and he said its been doing that since it was brand new, he bought it from my great grandma, and he says its so loud that no one wants to sit in the back seat
