I did that a couple times with a hand pump, and it is at least 15 minutes of pumping of each tire, and not just in emergencies. That was for the birds.

Now that I own a fatbike, I've been considering doing the same. The bike runs real nice on pavement at 20psi, but I need to drop the pressure quite a bit for off-pavement and sand. It'd take forever to go back and forth with a small frame pump. I can picture rides where I could switch back and forth from pavement to sand multiple times.
