I guess I'll bring it up at the bike shop when I take it in for an overhaul.
75 PSI should be plenty stiff on any tire over ~32mm wide or so. I use 700X32 tires and pump them to 75psi and I weight 260 lbs and it seems to work ok.
What are you measuring pressure with? I have heard that pump-mounted gauges can be unreliable but that is what I use and my tires feel plenty stiff at 75 psi
