which side wall works best with a transbrake, and have you used the phoenix tire w/ a brake. 31 compound vs the 9 with w/ a transbrake.. car weighs 3450 with driver, 4 link , 727 5000 stall conv. 900 hp.

I don't know about the Phoenix stairs but my car is similar except my car is lighter and I run A stiff side wall

Similar car here(3600 lbs)900 hp but I use Good years in 31/14.0/15 size with a brake and I knock the sidewalls out within 30 passes. Stiff sidewall is not available till 32.0/14.0/15 but I cannot fit that in my mini tubbed B body.

Hoosier makes the shortest ,smallest stiff wall slick from what I have found, 32 x 13.5w with 17.7 section, 14.1 wide and 102 roll out. These tires are rated stiff, versus semi stiff for the 33.6 x 15.1 Goodyears I am running now. I plan on trying them and have the gear for the smaller diameter. I haven't tested personally, but would think that a tube would help support these for better traction and longer sidewall life.

My heap is 2940ish with me in it. Being as I am a super class racer we get pretty anal about R/T and 60' numbers. When they start to waiver even a little the tires are replaced. Having said hat I run an M/T 30791 a 33x15 tire. I usually replace them at about 60 runs before any tire related variance occurs. They in turn usualy go onto a friends bracket car and last for another couple years without issue.
