20" 245/325 Tyre Pressures on 997T

Anyone driving with 245 and 325 20" tyres on your Turbos, what pressures are you using?
My car is DD (no track).

I am trying to keep 2.3 bar front and 2.7 bar rear, but I have no idea if this is low or high.

Yes. Rull of thumb + 2 PSI (.13bar)for every inch of increase in wheel diameter.

I run the following cold pressure:

Front-2.41 Bar (35 PSI)
Rear - 2.82 (41 PSI)
