Default MH drag radials, how much air??

Guys that are running these or any dr for that matter, how much air are you running and hooking on? Converter is a ss4000 with 2.6 str, 4.10's.

I'd say for street use around 20psi, and drop them some on the track. normal driving I'd keep them around 30 to help wear.

you wanting some for the track or to drive around on all the time? I think you'd be better served by a bias slick on the track FWIW

I run about 30psi on the street. 23-25 psi @ the track. I've tried 12-18psi @ the track with out any luck. 23-25psi works best for me.

I have the pinion setup at -3, and this is for a mix of both track and street. I hope having a cc helps, but this converter flashes high and hits hard. I've also heard the dr's don't need as much of a burnout.

Also, I don't have the sway bar up front so it transfers pretty good, hope it helps! I would like to cut some 1.75's, but I think mid 1.8's is more realistic.

Really depends on track prep & how many vehicles or out on slicks. I like John Force burnouts & then seem to work good, even if I hot lap it..

I just tried 25 psi on the street and I cant flat foot it, but it is a helluva lot better than the hankooks. I will play with it at the track, there will be A LOT of drag cars out, prep is usually badass at Prescott. I just want to be able to flat foot it and not have to lift or get in it gradual.

That converter only feels good now wait till it dead hooks, mine would flash to 4200 and wouldnt move an inch till it got to that rpm and grabed hard. I was able to hook with a 30 ince mt drag radial, I ran 10 psi. If your rim is plenty wide you can get away with more psi but I only had a 8in wide wheel so I had to to get all the rubber to the ground.
