How much do you weigh? I'd try LESS pressure. This will give you a wider contact patch, more traction, and the more comfortable ride you are looking for.
Tractive force is independent of contact surface area.
F=muN, where mu is the proportionality constant (coefficient of friction) and N is the apparent force of the surfaces pressing together (or W for weight, in this case).
