Danr55,
The way I look at is, it is what is comfortable for you to have on your car. If and when you ever decide to sell your car and the person that wants it doesen't like air in it, they can change it. I have thought about it for mine but the way I look at it is I only use my air in my daily driver about 15 days out of the year. But I do not live in Arizona. The average summer temp in the centeral vally of Ca. is probably around 85-90. The max it has been that i can recall is 115 and that was not very long in duration. Now last summer was a differant story but as luck would have it, I was in Chi-town on buisness for that one.
