What size are yours and what psi do you have them at the track.

I plan on getting some bfg dr's, 225 50 15's.

I'm thinking somewhere around 16-17 psi.

 

205/55/14 Nitto 555r drag radials on 14x5.5 HX wheels and I have run them as low as 12psi at the track without a problem. I was dropping the clutch from about 5500 rpms and I ended up pulling a 2.0 60 foot. I run them anywhere form 16-20psi on the streets.

 

Depends on your set-up...... looks like you have a H22A so I would think about your gears most H22 trannies are long geared so I would say 205/50's at 17psi if your all motor I ran those last year hit 2.0's and 1 1.9 with no traction bars no LSD. If you have turbo then get the 225's. I will be using 225's this year but I have short years...... just a thought. Rob
