I agree that a temp increase of only 10 to 15F should not result in pressure increase of 30 to 45 psi. Something is wrong.
What brand TPMS?
Have you confirmed TPMS pressure against a known accurate digital hand gauge?
What are your measured tire loads?
What speeds were involved?
I only see about 8 - 10 psi with 10 to 15F at 63 mph. Of course I have at least 20% margin on load.
I write a blog on RV tire application and safety. RVTireSafety.com
Also give seminars on tires at RV events across the US. 40 years experience as tire design & quality engineer for major tire mfg. Freelander 23QB on Chevy chassis is my RV
