I’ve never seen one from tire manufacturers that specially addresses road conditions, but that would be hard to do since weight, speed, and road conditions can vary so much.
But there’s no denying that airing down greatly improves the ride of the truck camper rig in most off-road conditions.
Keep in mind, most truck camper owners when they air down are traveling at a much slower pace off-road than at highway speeds on pavement. I would never do that traveling at highway speeds. The heat build up would destroy the tires.
