I'm not yet convinced. If I want to run 90 PSI, I simply stop pumping at 90
PSI. If I were doing this and having pinch flats (unlikely IME at <165 lb),
I'd run a 25 mm tire (which I do on the back in training anyway). Perhaps
the tubeless tires have less rolling resistance, but you can also get lower
rolling resistance by using a wider tire (e.g. 25 mm) of equal casing and
tread thickness. The main drawback of using such a wider tire is that it
won't accept as much pressure as the narrower tire, but lower pressure is
one of the claimed advantages of tubeless. Does anybody have (pointers to)
rolling resistance data for the tubeless vs tube question? Finally, I must
admit that I am prejudiced against Hutchinson due to the wretched quality of
their tires that were prevalent on the market in the '70s.
