i also want to add that in my opinion this also causes a slightly louder ride due to tire tread, both on smooth surfaces, and during bumps, and off-road or where loose gravel is present.
i got to thinking a few weeks ago, anyone propositioning a cheap fix for this slight nuisance?
IM THINKING OF REMOVING THE WHEEL, TAPING OFF THE PAINTED AREA'S, AND ANY CRITICAL MOVING PARTS, AND THEN SPRAYING THE AREA WITH PICK-UP TRUCK BED LINER, OR A RUBBER SEALING SPRAY I SAW IN HOME DEPOT.
i know i see a lot of guys spraying body panels with the bed-liner stuff, and it seems really good stuff. im thinking it would add a good sound barrier to the wheel well which already has pretty much this stuff on there, but i think a little more cant hurt.
