Hi, 4 tires for sale here, one is brand new, and three are used at about 70% tread remaining. Had to replace on of these tires and now I cant run these on my quattro as the difference in tread depth will screw up the differential. This isn't an issue on a front or rear wheel drive car. BFgoodrich G-Force TA KDW (the one with the aggressive looking tread) size is : 235/40/18 thanks Location: Bellingham it's NOT ok to contact this poster with services or other commercial interests washington
