Well this can be one of those Ford verses Chevy augments. When I needed tires for the Ram I went to the local long time dealer that I had dealt with before and flat out asked. What would be the best tires for the truck planning on towing a 5th wheel cross country. He told me that he has been a life long Michelin Guy but that he would recommend Cooper's and that is what he is running currently on his truck. So Had him install the Cooper's and they have been wearing well. around 10,000 miles on them so far. 5000 towing a heavy 5th wheel.
