Cold tire pressure vs hot
Trying to set a tpms system. How much should a 225-75-16 tire pressure rise from 60psi cold to ?hot?, assuming outside temp of 70*. On the tpms you set for cold pressure. It will alarm at 15% . I ...

The Ideal Gas Law (which for centuries has stated the change in PSI for a given change in temperature) is for gases (like N, dry air, etc).
Water is NOT a gas and expands more than a gas for a given temperature rise. Does not have to be boiling for the pressure increase to be more than for dry air!
