BFG DR air pressure?

[STL79Coupe]

I'm hoping to go to the track wed and I have a set of used BFG DR's. So what pressure would you start off with? I know a lot of variables but trying to get a base range.

What range of air pressure should I start off with using a "used" 275-60 -15 BFG DR? Car has a mostly stock suspension out back with a full drag setup up front (upr kmember, 90/10, and 175 coil overs). I was leaning towards 18-20 psi???

It's been 5 years since I ran drag radials but looking at my records I usually ran 16-18 lbs in my M/T 255/60/15's. I'd think somewhere around 18 lbs would be a good starting point.

My last outing, I started at 18 and due to bad air and minimal track prep, ended up at 13 on my MT's. 16-18 is always a decent starting point.

13! Guy's on Yellowbullet were saying under 16-17 they would get tire chatter. Than again they are probably going a lot faster.

I'm going to start at 20-21 and go down. It's an unknown stock rear with 4.10's.

I had 275/50/15's years ago and use to run them at 14psi
