Tire pressure built up over time sitting

[Ray,IN]

The 120 psi was not a freak of nature; it was a deliberate act, or all 6 tires would not have been the same pressure.

Sort of reminds me of a fellow years ago that came to coffee club and always insistent that his rain gage was out in the open and very accurate when it rained. He started always having more rain than anyone else and over a period of time it came out what neighbor was sneaking over to his yard early in the morning and adding some water every time it rained.

Yep, sounds strange. Even if they were filled cold and are now warm (80 is not that warm) .....I can't fathom any tire sitting 5 months and not dropping pressure. And as stated above, they certainly wouldn't all read the same after 5 months either way.
