I am looking at Cooper Discoverer A/T LT 265/70R17 tires for the Tradesman. Warranty seems great @ 55K miles and the price is in my budget. Anyone have any experience with these tires as to wear and road noise? A big question is, did these affect you mileage? I really like the Load Range E as it seems to stabilize the truck when I am towing my travel trailer. Any inf is greatly appreciated.
