Be careful to lower the pressure if you are going to have it out in the sun long also. I carry my pontoon and my tube in the back of a pickup, if I'm going to be stopped long in the summer I drop the pressure. The advice on the altitude was good also, in the east you don't have the exposure you do out west. Several years ago I saw a doughnut tube with an inner tube in it pop like a balloon. We figured the owner aired it up in Phoenix which was about 7 - 8,000 lower than where we were at Ft. Apache.
