Well lol Say they word Nitto, Pirelli, or any other top dollar tire in his shop or my four other uncles shops and you could hear a pin drop... My grandpa sold cooper tires and they all followed suit. I love the grip of the coopers tho and the ride is so quiet at first I even ran them through the winter and they did amazing for summer tires i never got stuck and it got hairy out a few times. I think the problem is the weight of the car and the cheap quality of the coopers. I don't know what to get next but i do know the next good rain we get will make a handful out of the XF. Every one has been praising the Hanook evos anyone know about how many miles you can put on them? I know driving style will play a big role so if your not pulling hole-shots and having rubber roasts please talk to me haha.
