How Much Will Tire Pressure Change From Cold To Hot On a Ford F-550 Super C Chassis?
Question:
I have a super C on a F550 chassis. I have Michilin tires 225x70x19.5 that calls for 110 psi. When driving the tires heat up and the tire pressure increases what would be the max tire pressure before I should stop and let some air out of the tire

Expert Reply:
The tire pressures called for either by the Chassis, RV or Tire manufacturer are the cold inflated tire pressures. There is no need to adjust the tire pressures while you drive unless you are travelling very long distances and in different climates. If that is the case I recommend when you stop for gas or food stops to verify the pressures after the tires have had a chance to cool off. If you are looking for a warning to set for a TPMS # TM98FR do note that tire pressure increases by roughly 10% from cold to warm so I would set the high warning pressure at 125psi.
