Not necessarily. Lots of factors go into the "speed" of a tire. And you might find that 25mm tires give you a lot more comfort and durability. Your weight and max psi don't correlate. Max psi has to do with the tire construction, just like the rolling resistance.

Over-inflated tires are susceptible to gashes and have a harsh ride. Under-inflated tires are susceptible to pinch flats.
