Thanks Dallas,
Yes I totally agree with you and what I meant was to get a starting point. I've never worked with vintage tires and always had charts with track tires to optimize setup and pressure fairly quickly.
I have intuitively set the pressure to 28 lbs for street (1.9 bars) and will then start with 19 when the car is tracked.

Are you using these same rubbers though?

Thanks for the info.
Luke
