What do you do? Tire Pressure.

I think this subject has been discussed in the past but lets do it one more time. It's about tire pressure. I live at 5000 ft elevation. Last week in preparation for a few days at the Grand Canyon I pressured up the tires to 80 lbs, using good old air, not nitrogen. (Maxxis 8008). I would say the temp was about 50-55 degrees. MY TST read 78 lbs. on each tire. (I mark that up to tolerances in my gauge and the TST). Yesterday in preparation for leaving the Grand Canyon after four nights the TST was reading 73 lbs. on each tire. So a drop of 5 lbs. at cold temperature. I didn't check with the gauge as I didn't want to let out any air, but all things being equal all tires were down a full 5 lbs. The elevation at the canyon is about 7200 feet and the temp when I pulled out was about 45. All the tires eventually warmed up to 82-83 lbs. So since the cold pressure is 80 lbs. are you supposed to air up the tires prior to departure each time this happens due to temperature?

Thanks

Only air up the tires if you plan on staying and traveling at that elevation.

I live in Yuma, AZ (elevation around 150 feet) and aired up my 5'ver tires to 80 PSI before heading to Sedona, AZ (elevation at 4350 feet) last month for a few days...about a 250 mile drive.

Tire pressure after arriving and cooling off was around 76 PSI.

Since I was going to take the same drive home (mostly down hill), I left the tires and they were at 80 again when I got home (once they cooled off, of course).

I have a TPMS on my 5'ver...

The tire manufacturers say that a rule of thumb for tire pressure is around 1 PSI per 10°F change.

I check my tires and air up if needed before I head out and keep an eye on them daily. Made the trip to Alaska in 2016 and only needed to add air to one trailer tire the entire trip.

Google 'TIRE PRESSURE TEMPERATURE CHART" A lot of good, explanatory information will come up. I downloaded a chart from somewhere years ago and have it taped to one of the doors on the trailer.
today I did my typical prep for our trip back to Ohio and then back to Florida. It is 59 deg. here at Cape Cod NS where I am a ranger. At 65 degrees the tires are to be inflated to 110 psi. At 59, I only need 109. Minor difference. But if the outside ambient was 80, the recommended adjusted tire pressure is 114 psi.
