Before each road ride I top my tires to the recommended 100 psi with a floor pump. I have a frame pump but use it only in emergencies, at which time I was able to get the tiers up to about 85 – 90 psi. That was enough to get me home but I would not want to do a multy-day tour like that.

Next summer I would like to start doing small overnight tours. What pump and what method do you experienced tourists do to keep your tire pressure topped off?
