So....
Tires on the old/early 930 are tired/ancient/hard blocks of rubber
Car is NOT shown at concours, and although driven a bit aggressively, likely will not see track (hasn't yet, and no time to pursue those pleasures)
Car lives on Wet Coast...BUT...only sees rain when a cloudburst appears...
So...dry driving is predominant use.
