Ok Here is my experiences with slicks and air. Keep in mind mine are 33/10.5/16 with no tubes. On the 1/8 I have found out I can get away with lower air. In the 1/4, once it locks in high gear it can turn into a controlled crash with lower air. I run about 15-18psi. Track temp plays alot of roll in setup, the colder the track the lower the air. Be very careful with lower air because it will be like a boat when idling through the no wake zone. You will be steering side to side. Also keep in mind the braking aspect. Most times people think of getting traction at launch and make it to the 1/8 or 1/4 mile beams, most times forgetting the slowing down for the turn off.
Story time!!!!
In Tulsa the bracket class there was a truck with a 26sec dial. I got to line up with him and his 1/8 mile was my 1/4 mile times. So as I blew past him I slammed the brakes trying not to break out and when I did the slicks stood up and I almost put it in the wall. I pulled off the track and no lie I was shaking and thought to myself if it was worth it. Stopping can be a hairy deal if no cautious.
Crandall got crazy at times and I am not sure why. I was looking at the wall in my mirror.
So in the end please take it easy dropping air in these tires with such heavy trucks. The awkward weight makes things a little more crazy.
