Run your air bags all the way up, inspect them for any cuts, abrasions, or exposed inner cord, also check the seats for any corrosion or rust. I suspect you will not find any. A few weather cracks in the outer covering are ok. If all is good run em. The air bags have a lot less movement, there for are not like your tires which are exposed to a lot more stress, (heat, abrasion, impact, and sun). Even with the inner cord exposed (not cut) the bag will still run a long time. In short the air bags are very tough, and one of the last things to worry about. we run them on most of our trucks in construction and short of damage by things cutting them we never change them.
