Tire Pressure Increase

[bmerpaw]

We travel from Canada to Florida each March & mine will increase 20-25 lbs & go back down when re return home. Dealer said to leave them alone, that this is normal.

As your tires heat up the pressure increases. When we start out in the cold our tires can be around 80 PSI and once we're on the highway on a sunny day the pressure will go over 100.

I've had the tire pressure go up 35 lbs on desert 120 degree temps. The road temp was probably 150 or more.

I used to travel from Wis to Albuquerque in Feb each year. I would air up my tires in my unheated garage with temps below 0. I owned a 97 Adventure with 16" tires. 2 years in a row I would blow out a couple of tires when I got to Albuquerque. After a lot of research I found I was blowing the tires out by over inflation. In following years I would retest my tires after getting in warmer temperatures. I would always have to let air out to get back to normal. When I got back home I would have to re inflate my tires back to normal. It was a pain to have to do this but I never had a blow out again. Now that I have a TST I realize fully what was happening. I had PSI increase do to not only temperature but elevation as well.
