Dresser Tire has a chart for tire pressure. Depends of the size and no of plys. Good place to start.

Default Under pressure

I used to run ~25 psi in my -3, but now run closer to 50 psi. I've never had shimmy throughout that range. Not only is the plane easier to roll around there's no chance of slipping a tire on the rim. When we do formation ground maneuvers we often spin on one of the mains.

At 23psi, no shimmy. At 26 psi and over lots of shimmy on the left leg at the end of the roll. I found this out by letting the tyres gradually deflate. No science!
