Unsure of Proper Tire Pressure
I don't know what kind of tires you're running, but 65PSI is a really low maximum pressure for a 700x32 tire. I wouldn't exceed it if I were you. I'd probably throw them out and get a pair of tires that are a little more confidence inspiring. 
Tire pressure is more of an art than a science (even moreso with mountain bike tires), and much of it is going to come down to preference. The skinnier the tire, the higher the pressure. The bigger the rider, the higher the pressure. To a lesser extent, the higher the TPI (threads per inch), the higher the pressure. There is a sweet spot between the min and max pressures, and it depends on the mentioned factors and more, and each rider just has to feel it out for themselves. That said, Michelin has a chart that can provide a decent starting point for road tires and you can go up or down from there as you please. Keep in mind they've designed this around their own tires, and ultimately other reputable sources probably have other opinions on the matter. 
In Michelin's words:

 Just as with your car tires, proper inflation pressure is very important to how your bicycle tires perform and last. And as with car tires, the most important variable that affects what the proper pressure should be is the load your tires are asked to carry.Thanks to more than a century of tire technology research, Michelin engineers have found that there's a certain amount of deflection in the tire profile that's optimal for balancing grip, efficiency, comfort and durability. That deflection is based on the tire's construction and the weight of the rider. Obviously, your style of riding can have an effect too, but the chart below should give you a reasonable guide of where to start when experimenting to find the proper tire pressure for you.
