tire air pressure

I have had some tire problems in the past so I know a lot of the do's and don'ts. So I have this question which I probably know the answer but I will throw it out here anyway. The last 2 years we have wintered in Florida and this year in Arizona. Being from Minnesota I left in the cold and I made sure that my tires had 80 psi in each tire like it should. I did not check the tires until today and all 4 had 90 psi in them. I checked the tires today because we have been sitting for 3 weeks now and it needed to be done. I did not check the tires until now because it was still plenty cool as far down as Lubbock TX. I know there is a difference in warmer climates as well as elevation too. But should I be checking the tires more often on a trip (provided they are cold) than I have been? I did put all the tires back to 80 psi.
Thanks,
Bill

    I respectfully disagree.

    In response to spindrift and anyone else who is interested, when I was having my tire problems the last 2 years I was getting a lot of help in this forum and the overwhelming response was: first always check tires cold and second, if it says 80 psi, then that is what you put in. Besides, I did weigh my rig on a CAT certified scale and I am within about 700 lbs of maximizing the weight limit of cargo put in the coach. I plan to stay within those numbers too.
    thanks,

    On any of my trips fro a cold climate to warm, I will check air preasure every morning there is a 15 degree up surge in temp. I don't worry to much about mountans.

    Tires should be checked each morning before traveling for the day. If you're not traveling no need to check them unless they are low enough to APPEAR low. There are a LOT of things other than temperature that will have an effect on your tires (barometric pressure and altitude) to name two.

    Do you have 80psi in your tires because that's the max air psi rating for the tire? Or did you weigh the rig and determine that 80psi was the pressure you needed for your load?

    I will always check before leaving for a trip.. once on the road I will check at each rest stop but NOT adjust air out... They will have more pressure in them from being hot.. As long as the tires are at the proper operating temp when you leave,, your good to go.
