Hmmm,,,, 22 is about what I run in my BIG Letter Goodyears, as do a few of my friends with replicas running Goodrich T/A's.

Light car with BIG tires = low psi

I run 15 at the drag strip for a little more "bite" out of the hole, but the car gets squirly in the rear when I "nail" 2nd gear with the pressure that low. 22 also greatly improves the ride quality with a little softer tire.

The key is watching how the tires "wear". Good even wear across the tread indicates your psi is correct! 22, working for me.
