I think to each their own, but on my 2014 F150 Max Tow/Payload Pack/OffRoad Pack 4x4 EcoBoost I have 275/65/18 E rated truck tires that I personally run 45#'s cold. My Outback 328RL has 225/75/15 E rated tires that I run at 80#'s cold when towing.
Works great for me....ohh and 50#'s in the Loadlifter 5000's[emoji106]
