Seen massive variation in what people run across different terrain types here. Starting a community data thread — please share your pressure settings with your tyre size and terrain type. I will update this post as we collect more data. Especially interested in summer versus winter figures and dune type differences.
285/75/16 mud terrain: highway 40psi, graded track 30psi, soft sand 14 to 16psi. I run lower than most but have never bogged at those pressures on a loaded truck.
Important UAE note: heat soak builds tyre pressure fast. Air down at 7am in winter and you are fine. In summer the pressure build can be 4 to 5psi in an hour. Check regularly and adjust.
Never go below 12psi on standard AT tyres without bead locks. Risk of debeading is real. Changing a tyre in the Liwa heat is genuinely dangerous — take it seriously.
