Pressure Pro question

[garyka]

I left SC this morning and the temperature was 37 degrees,when I got into FL.the temp was low 70's this was causing the tire pressure to up enough to start mt tire pressure to reach 92 lbs and setting of a alarm.Whats a good role of thumb to prevent this?

I have set my high pressure to 105. But I would get a maximum high pressure rating from one of the tire experts like Lonnie B. Good question.

You have the Pressure Pro? I do too, but didnt know it has an alarm for too much pressure.

Anyhow, ambient temp really makes a big difference in tire pressure. I've set my pressure to 75 the afternoon before we leave on a trip, then the next morning the pressure will be down to below 70, depending on the outside temperature.

I don't think there is a way to get around this. 37 degrees going up to 70 is a really big difference. The only thing I can think of is when you stop at a rest area, recheck and adjust the pressure down some.
