Most 700c road tires 35mm and under are designed to run at 80-110 PSI. 35mm tires are kind of in between wide tires and narrow road tires. You should run them at least 70 PSI in my opinion.

Tire Width=35: Pressure(psi) = (0.17 * Rider Weight in lbs) + 33.67 for normal conditions.
a bit less, like 10% less for sloppy conditions.
