there are 18s now that approach the load rating of 19.5s at 4080 lbs for the 18s. That might be worth a consideration.
If you aren’t maxing out the pressure on the 19.5s, you could end up being equal with no ability to air down when the TC isn’t on the truck much past 70. You’ll pop the bead on a 19.5 if you air down. Also, the speed rating is much less on most 19.5s.
Thanks Jim,
Michelin's site suggests air ranges from 75 - 120. That said, the camper is always on the truck, and when it's not, it just a quick trip to the lumber yard.
Also, Those XDEs are just under 5000 lbs with a snowflake rating. Not sure which 4000lb tire you're referencing. Wonder if it's snowflake. I have the Nokian LTs right now and they've been great. I'm just thinking of a heavier camper (or upgrading to a dually, but changing trucks seemed like an easier proposition before the pandemic).
