255/35ZR19 96Y. Haven't tried the 75 yet. My gasket blew for my blow down kit the other day at an intersection. Scared the @#%!#$^ out of me! I looked in my mirror and it looked like my car was sitting on a cloud haha

 

I'm not up on all of the nitrous-lingo, but is that the purge valve or noid that blew?

I'd really like to get a set of dedicated drag wheels and get some drag radials. Then get PPE headers and 75 shot. I really love to get a set of the Weld RTS wheels with Mickey ET Streets.
