Here is an example of tire pressure tuning for max grip

Autocross is an excellent example of "real world" because many people use street tires, the speeds are typically under 60mph and the tires don't get to "track temperatures". The turns are often quite similar to what you would be doing in an emergency situation - slam brakes, sharp turn.

Note that they don't say anything about "max sidewall pressure" because it is FAR out of the range of "max grip". Point being, bigger ain't better and further from optimal is less than optimal (gee). Safety first kids.
