275/60 BFG-DR's... what air pressure

[DCVING 6]

I've got a pair of 275/60/15 BFG drag radials on a stock T rim.

What is a good air pressure for around town? I started off with 30, looks like the tread is pretty muchly even on the ground.

Also for at the track, I know I will need to fine tune to see where my car likes it better, but whats a good range to start with?

Thanks.
