Hi
I have a 2015 DSDP
I recently installed a TireMinder air pressure monitoring system.
I have the tire pressure set according to the Michelin chart based on corner weights.
I was surprised when my alarm went off after have been on the road for a while and the tires heated up shooting the air pressure up to over 130 psi.
I called Michelin and they were no help at all.
Does anyone know what I should reasonably expect the tire pressure to climb as the tires heat up.
I suppose it's has to do with what the temp is.
Outside temp today was 80 I was traveling on I 95 southbound ranging between 65-70 mph

You don't say what your starting psi was, but yes your tire can & will build pressure rolling down the road. On my coach, I was running 115 starting psi and they would build easily to 135 psi on warm days. You need to raise your alarm level up to reduce those unwanted alarms.

Normal is that the tire pressure will increase by 20%. So I would set my alarm at +30% and -10%

Or you could run N2... As our new truck and jeep uses. Temperature is not an issue! In reality how many of us are going to rent a N2 cylinder for our MH's?

+1

I had the same thing happen as I originally set my alarm at 20% above and we had a few warmer days and the alarms starting going off. I plan on changing mine as stated above to same ranges.
