tire pressure and extreme heat

Early morning - check and fill your tires to the max as recommended on the side wall and the placard on your tow vehicle...

I'm pretty much in agreement with this but not everyone fills tires to the maximum pressure listed on the sidewall and there may be reasons for that.

I think some folks get nervous when they measure pressures after a run in hot weather. The pressures will be above the sidewall recommendations. There's no reason for alarm as the mfg has built the tire and calculated the tire pressures to endure that rise. There is far more stress on the tire from under inflation than being a few pounds over.
