that makes a lot of sense to me. on my mountain bike i like to fill up my tires at home for riding on the road and when i get to a trail i let a lot of air out. i don't use a gauge i use my fingers but i have used a gauge enough to be pretty accurate with my fingers and i go by what the road conditions are for how much air i let out. so i never use a tire gauge except for the one on my pump. i guess when i get my luna orbit a gauge might be more necessary for me.
