I'm 5' 10" and 200# and ride Conti gatorskins 700X25. What would my best PSI be? I often ride on sketchy roads and I'm an older rider, so control and harshness are two concepts important to me.
I'd start out with 100 psi front and rear. Then back-to-back, try 90. If 90 is more comfortable and you aren't squishing the tire, try 85. you'll get to the best mix of pressure, rolling resistance and flat-resistance.
A caveat, though. If you are racing almost all of your time will be lost on the hills. Lighter is better when you are climbing, so those comfy 28s start to look a little worse. So...you still have to consider weight trade-offs along with tire pressure/rolling resistance.
Otherwise, I'd be running 1200 gram Rubber Queens, for sure!
