I wonder what are the best tire pressures.

In PC1 most of the time I set up tire pressures in a way, so that they will be around 2 bars in race when heated up.

In PC2 I found out, that most of the Cars I tested have less basic pressure, around 1.30 to 1.45 bar, which in fact results in less than 2 bars when heated up.

So I regular increase pressures to around 1.60, to get near 2 bars in race, which works good to me (since I get used to it)

No I wonder if I am right or if 2 bars are too much? It's clear that this depends on track temperature, tire type, car etc.
