Perhaps, but it has been over 600 miles since i have gotten a pinch flat (or any type of flat). but
on the other hand, perhaps the gauge on the pump is not accurate. i usually pump them to a
particular firmness, i have felt the rim hit on a few bumps, but none of them resulted in a pinch
flat. and there again too, the hits are on the rear tire, and that one has a slime filled tube.
perhaps i do get pinch flats, but they never actually go flat. could be an advertisement for slime
;-) i'll check with a proper gauge... ok, back was at 20, and front was at 21. so i brought them up
to 45 and 50 respectfully (i always like to run the front a touch more, don't ask why, cause i don't
know why). i can imaging it wile ride like a dump truck now, but i shouldn't feel the rim hit
anywhere anymore. should even roll faster. the tires stated a psi range of 40 - 60 (never actually
noticed this before), so at least they are within specs now. i can't imagine running them at 60
pounds, just seems a bit extreme to me (i got a bit scared just bringing the front up to 50). have
to take a quick ride and see if it improved the rolling resistance any (should have).
