Question: Presently in Albuquerque.... came in from Houston, tx....getting ready to proceed to St.George,Az.... all tires are about 5 lbs low.... how does temperature and altitude affect tire pressure as I proceed North.... do I need to fill the tires back to normal traveling pressure every morning before I get on the road? Thanks

5 pounds low..... lower than what?

Here is a second method of determining the correct pressure for the tire vs the load being carried.

at each stop during the day check each tire for being hot. if you find a tire hotter than the others, raise the pressure 10 pounds. when they are all hot raise them all.
