I have EEZTire TMPS as well and was just as confused so I contacted Michellin and here is what I got. Of course I have the 22.5 tires so not sure if it would change for the 19.5 tires. Here is the exchange with them, I hope it helps.

Hello Erich,
Thank you for your email. We welcome the opportunity to serve you.

In regards to the email you sent stating:
Thank you for the quick response. If I understand you correctly, spikes between 6-12 PSI are normal. I maintain my tires at 100 PSI, the recommended PSI. I have seen spikes up to 120 PSI when traveling for a long period of time in warm climates. The ultimate question is, under normal driving questions, what is the highest level spike that is acceptable under normal driving conditions with a 100 PSI being maintained as the recommended pressure? Basically, I need to know what to set the TPMS max before the alarms start going off and I need to be concerned?


Spikes between 6-12 psi are normal in normal driving, and weather conditions. Based on your tire information, the max pressure would be 110. The tires should never be initially inflated to anything higher than 110psi, however due to reinforced sidewalls, steel belts,and tread compound the tires are actually able to withstand up to 25-30psi over this max pressure.

If your initial tire pressure asks for 100psi, then your warning level would be at about 125-130psi. When reaching these levels we recommend allowing the tires to cool down and going back to 110 so that there is no tire failure.

We would suggest setting your TPMS max at about 120-125psi.
