Embarrassing to say I've never used one. I have the adapter but have always relied on my floor pump at home and my mini-pump on the road.
I avoid the gas station air pump out of fear that I will blow up my tires in an instant. Is this an unreasonable fear?
I think I should get over it because I cannot get the kind of pressure that I want from the mini pump when I'm out on the road and a floor pump is unavailable to me.
