I suspect that for either the "high pressure" or "high volume" pumps, the maximum pressure they note is probably only attained at "busting a gut" levels of exertion (at least for me). For the tires...

I'm only aware of these because I was shopping for another pump recently. Wow, so many different models!

Lezyne considers the Pocket Drive to be one of their "high pressure" pumps suitable for road bike tires. It's just going to take a relatively large number of strokes because of the very compact size....
