[Yak] tire pressure as a function of tire width and weight

[Jym Dyer]

=v= I've read all of these postings with interest, and I
understand the theory, etc.  But what I find when the rubber
hits the road is:

  o If I don't pump the tires (or tyres, if you will) up to
    100psi, I get flats.

  o If I use Schwalbe Marathon Plus, at 100psi, I get very
    few flats (the rubber cement in my patch kit dries up!).

  o I used to use Schwalbe Stelvios, at 100psi, which did
    seem zippier but occasionally got flats.

  o If I use Primo Comets, I get flats no matter what.

I don't weigh a whole lot (175lbs is normal for my height),
but these are my experiences.  Thinner and high PSI works.
What's up with that?

=v= I've always wanted to try out Scorchers (because, hey,
http://scorcher.org/  is me), but never had the opportunity.
