Hiya:
So, when I picked up my new bike at the LBS, I asked about how low I
could/should go on tire inflation. Background: It's a loaded touring
bike with 700x32c tires, max pressure 110 psi, I weigh only SLIGHTLY
less than 150 lb and my food-oriented usual group ride group has an
instinct for finding really bad roads (Harmony Grove Road, 30th St.,
etc. for those who've experience with San Diego and the joys of riding
"deferred maintenance.") And I won't usuallly be riding with a full
load -- I just wanted a drop bar pickup truck that could take the
commute and the grocery store run.
The answer -- "Don't go under 100 or you'll get pinch flats." This
somewhat shocked me, because I've met a few (really slender) brevet
riders who put 90 to 100 psi in 700x23c tires. I mean, what's the point
in getting the big wheel if you can''t get some decent cushioning out
of it?
