My new FX4 with the sport package promises AT (all terrain) tires. The truck arrived with Michelin Primacy XC tires. That's the problem these tires ate highway tires not AT. The Ford Motor co. believes these tires are in fact AT. I checked the Michelin web site they confirmed that they are highway tires. Mine is not an isolated incident. I have checked many F150's with the sport package and they all have the same highway tire. I am considering small claims court or maybe a class action suit
