Tomorrow im picking up my 205 50 15 bfg g-force t/a's which are going on a regualr 15 in steelie. What is the best pressure to run with these things. I have neever launched on a drag radial and im hopin gi can cut a 1.9 or a 2.0. I want a 2.0 at least, is a 1.9 even possible with our cars?

I ran Mickey Thompson Slicks and cut a 1.888 60'.

I had my pressure at 12 psi. I think you'd run it higher in a drag radial though. Start at 25 PSI and then if it spins lower it a couple each run and see how it works for you.

i have the drag radials not the t/a's but my friend has them on his rx-7 that has a T78 turbo conversion and he runs them at about 15-18 psi. the max he tried was 19 psi. my drag radials i keep to about 19psi all the time, and according to the g-tech i get 2.0- 1.9 60's foots.
now you know that ether one of these tires is going to reduce your trap speed.

The fastest times I have heard on B15's with that size and make of tire were run at 22psi in front.

oh and make sure you heat cycle them otherwise they won't be nearly as sticky as they can be. and what i mean by heat cycling is on the day you first get them, drive 20-30 minutes on them without spinning your tires (its very tempting i know, but you must resist!) and let them sit overnight, the next day they'll be ready to rock!
