Maybe. Calculate the relative change in volume of a 26
x 1.5 tire, then the change in pressure.

No kidding. Carl's reading comprehension is *way* too low for an English
teacher. For reference, here's the quote to which Carl refers:

"Think of it this way - imagine trying to drive a nail using a bicycle
stem on an upside-down bicycle as the contact point with the nail, and
hammering on the front tire. You'd certainly have to work to get the
road bike's nail driven, but you'd never, ever get the nail driven
using the downhill bike as a buffer."

Carl distorted the original quote by an order of magnitude. And
"familiar?" How about a few cites to show that it's been said before?
I've never seen it.
