A little note to add here
If you purchase a small tank and a regulator designed for nitrogen gas to fill your tires with you will have less fluctuations in pressure both during your ride and between rides.
Drain the moisture infected air from your tire completely and fill with nitrogen, drain the tire once more then refill with nitrogen. This dry gas will stay stable over long periods of time and a hidden benefit is little to no corrosion internally over much longer periods of time. (Most museums do this)
