are there any ballpark figures for what PSI one should run in various types of race?
in my case, I'm about 117lbs right now. I've got one road race coming up in Singapore; it's a flat circuit race. and I may have a crit in Detroit - that course features some very rough pavement. I'd always just pumped my tires up to maximum ...

I generally run around 120 with clinchers no matter what the tire says. With Supersonics, maybe 130. Much higher than that, and the ride gets rough and you risk blowoff.

For tubulars, I generally run around 130-140, but I've gone as high as 170 or so for time trials on smooth pavement. At higher pressures, though, cornering might be impaired.

With your light weight, I'd probably run around 110 in clinchers.
