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?
