This is something best practiced AT HOME with the tools you would have with you on the bike. Some wheels
are easy to remove from the frame and some are not, but more importantly some tire/wheel combos are more
difficult to deal with than others, and as prior threads have shown, there are a few tires that just cannot be easily
removed and very difficult to replace on the wheel without puncturing the replacement tube. So do this at home
several times before having to do it on the road. Most tire/wheel combos are not that hard to handle but it builds
confidence to have done this before hand.
Finally it can be more difficult than you realize to pump a road tire up to adequate riding pressure with small
frame pumps. Pumps such as the Topeak (
https://www.topeak.com/global/en/pro...%C2%AE-digital ) with a flip out base and an extension tube that fastens to the valve
and allows the pump to be placed vertically and stabilized with your foot while your upper body does all the work
are much easier to get that last 20# of pressure in the tire.
