High pressure is kind of a racers myth. I someplace have a study done by Bicycling magazine in the 1990s that basically said the higher the pressure the more flats you will have. Roger
I'll probably try 100/110 psi front/rear. I may try some wire bead tires - I have some a friend borrowed but did not use that I bought earlier. The current folding ones don't have much strength to the bead area. I do like a couple folding tire brands; it would be too bad if I couldn't use them. Of course, it's not worth a blowout even if it doesn't cause a spill.
