Goodyear Polyglas pressure?

[VintageMusclecar]

I know this subject has been touched on in the past, just looking for what the current trends are.

For reference, I'm running F70/15 on a 15X6 up front and L60/15 on a 15X8 in the back. Currently running 32 lbs on all 4 corners.

I managed to get the car out for a brief drive yesterday (first time since I got it back from alignment over a month ago, fwiw). I got after it a little bit, and <span style="font-weight: bold">much</span> to my surprise, it actually hooked <span style="font-style: italic">surprisingly</span> well in 1st and 2nd gear (albeit from a slight roll).

Just wondering if I might be able to bump the pressure(s) up some to help with road feel w/o losing the hook.

Thanks as always.
