I put the 285/70/17 BFgoodrich All Terrain tire KO on my 2003 F-150 FX4. I love them. (look at the gallery). I can hear them, thats because of the exhaust. I paid $170 for each tire plus shipping, and I paid $35 for the road hazzard. No problem with clearance. The only thing I don't understand is why I cant do a brake stand. Its probley a good thing, I don't beat my trucks. Only drive them hard off road.
