I just installed a set of Nitto drag radials, and I am headed to the track this weekend. I always ran conventional slicks. Looking for info on where to start with the drag radials, tire pressure, burnout procedures, etc.
Update from the weekend. Started off at 20 lbs. First few runs just blew the tires away at the starting line, even after decent burnouts. talked to everyone at the track I could find running drag radials (but not Nittos). They all said they were running 15-16 lbs. Lowered them to 18 and then down to 15. I think what finally happened was that I burned through the outer layer and they started to get stickier. I also think lowering the air pressure that much was a mistake. I was getting weird wheel hop like movement out of the rear suspension (super stock springs) that I never had with the slicks. One other thing that worries me. I marked the tires at the valve stem, and by the end of the day the drivers side tire had rotated 180 degrees on the rim. The passenger side moved about 6 inches.
You're assuming that the tire only rotated 180 degrees...:burnout:it could have rotated many revolution then stopped 180 degrees from where it started???

The rims are already drilled for screws. Can you use screws with drag radials?
So how did it do? i don't think the nittos are best for that HP they last a lot longer than the M/T etc.. they are great on my demon with about 400 hp, on the street.
Hey my demon has got 400 hp too and im running 275/60r15 bf goodrich radial t/a . Can you tell the difference on launch between the street tires and drag radials? I think i already know the answer but just curious
I run the Nitto's on my 69 fastback and run them at 16/17 psi depending on track prep.I had to put screws in mine also as they were spinning on the rim(my 60ft improved also)
The more I think about it the more I think the tires were spinning on the rims, more than just 180 degrees. I am going to have them dismounted and clean the lubricant off the beads and put the screws back in. I am ever glad I didn't decide to weld all the screw holes up!
