Extra 10#s

[MAMalody]

I am in for the winter, and full-time in my rig. I am thinking of increasing tire pressure for 80# to 90#. I don't plan on going out until March of 2011. What do you think?

Mike you lose 1 lb. of tire pressure for every 10 degrees of temp.drop. I would check the temp now and when you move next then adjust based on the current temp.

I have seen articles that over inflating the tires when storing a rig (or the rig is NOT moving for a while) can help prevent flatspotting when the trailer sits for too long. I suppose 10 miles over the maximum should do it but I think a tire expert would have a better answer on how much PSI would be safe. The key is that the rig will NOT be moving.

what is the highest tire pressure rating on the tire sidewall. i would not go over that rating.if the tires are in the sun the sun will heat the tires up and the pressure will go up.

The manufacture gives us this cold pressure rating but their is one heck of a difference when set cold in August than when set during say January for us. Just for example, our dually was last adjusted in September and just last week when the temp was down to 25 and we went and got it out of the insulated garage and soon two of the alarms were a blaring. The pressure drop was 7 lbs. So Mike if we were to set up our Monty cold pressure at 80lbs. today and drive south to snowbird and rechecked our cold pressure when we got there I know it would be at least 90 or more. Do those snowbirders adjust their cold pressure each day along the way??? If you are not moving I would certainly adjust them up to the 90lbs after all, an 80lb. cold pressure is 90lbs. when one gets rolling down the highway.

I have seen similar acticles described by Art...adding some air to avoid flat spots while the rig is in storage. Also, as we are traveling from the North East in late fall southward, we do adjust psi every day to account for outside temp fluxs...one day the heat is going, the next we have both a/cs hard at work...makes for some interesting psi readings along the way!
