Since you have the max tow pkg, then your truck probably came with 18" tires. You have a lot more choices for replacement tires than those with 20" tires.
My 2012 came with Michelin LTX A/S P265/60R18. I have over 8,000 miles so far, about half towing a 5,000 pound TT, including several days of rain while towing over 400 miles per day. Those tires are great, wet or dry highways, but I don't have any experience with them in snow or ice.
Michelin makes a few other treads in that size, including A/T2, M/S2, and Latitude A/S. I would definitely go with Michelin, but which tread you choose depends on where you live and how often you go off into the boonies "off road".
Cooper would be my second choice. If you have 20" tires, Cooper makes 5 different treads to choose from in size 275/55R20. The Cooper Zeon LTZ is a good compromise between highway and off road: "The Cooper Zeon LTZ was developed as a hybrid between a sport truck tire and an all-terrain tire. The aggressiveness of the Zeon LTZ can tame any road surface while providing excellent ride and handling capabilities."
If you have 18" tires, Cooper makes 3 different treads on size 265/60R18.
