That's grams, not ounces.

And it's a pretty horrendous misuse of resources just to avoid pumping.

Try pumping oh say a 700-25C tire to 90 psi with one of those little
short pocket sized pumps :-)

Lezyne make a range of bike pumps. I use a small "road drive" model,
that would easily fit in a back pocket, though I much prefer using the
holder that attaches between the frame and bottle cage.

I have absolutely no problem pumping up my tyres to 90 psi and more. :-)

I have no problems with pumping tires to 90 psi but sitting there on
the side of the road with the rain beating down and the cars zipping
by splashing mud I just find it a lot more satisfying to use CO2 -
"psssit" and you are back on the bike. :-)
