I guess I'm just lazy old man. I simple replace the tube. The first thing I do when buying a bike with a different tube size is buy 4-6 quality tubes and store them at home keeping one in my trunk pack on the bike. If I get a flat I simply change the tube. I carry a patch kit but have never used it. In the event I get 2 flats on a ride I will have it to use it. I'm a fan of long slow rides and unfortunately can't rely on anyone to rescue me, and rideshares are not around most of my area. So I need to make reasonably sure I can keep my tires aired up.
