Tires for street and drag racing

I have 275/60/15 Nitto 555R2 currently. A couple weeks ago I hd the most success with these tires. Compared to last year. They like a really good burnout(for my car maybe). I am still working on some things but they hooked great on the 3 passes I got that day before rain showed up. My car is a 72 Demon with a 512 low deck, 4 speed, 3.91s. Best 60' to date is 1.68 launching around 3k rpm. I also run them on the street and they hook great there. Last season I struggled getting them to hook. They were very inconsistent. I also wasn't doing a huge burnout at that time. So that may have been the trick I just learned. We will find out in the near future if that is the case. I will be switching to Hoosier CO7 slicks soon though. Best of luck!
