Towing 5'er, mountain pressures
As a resident flat-lander from the fine state of Iowa, we travel west at least once a year to Colorado. This year I'll be towing my 5'er Toyhauler.
When I'm pulling my toyhauler, I always try to have maximum rated pressure in the truck tires. In the case of my Nitto's, that's 80psi.
I know from experience that tire pressure increases up in the mountains with altitude. Starting off at 600ft of altitude with 80psi max pressure, and climbing over 12,000-ft mountain passes, should I back my pressure off a little before I start up the grade?
Has anyone had any experience with pressure changes going over mountain passes loaded heavy with that drastic of altitude change? I'm not even sure how much fluctuation to expect at that kind of load.
