Another post here about keeping tires inflated, reminded me of a question I've been wondering about. When I had a shop many years ago, our compressor had specific provisions to get freed up water vapor out of the compressed air. I look at those little electric air compressors at gas stations, and wonder about that water vapor. I've found if I use my gauge torelease a blast of air from the hose after the compressor starts up, I get a small cloud of vapor that otherwise would have gone in my tire. I can't believe adding water / humidity to ones tires is a good thing.
Anyone have any info on this?
