Here you go!!
Proper use of Mickey Thompson ET Street Radial
Inflation Pressures
On the racetrack DO NOT use starting pressures below 11 psi.
Recommend pressures for:
P295 and larger sizes: 11-14 psi
P275 and smaller sizes: 12-16 psi
On the highway we recommend running 75% of the max psi as notes on the sidewall of the tire.
Burnouts
The tread compound used in the ET Street Radials is designed to heat quickly and does not require a heavy burnout. Continue the burnout until the engine starts to pull down. We do not recommend a dry hop after the burnout.
Bead/Wheel Slippage
Some bead/wheel slippage may result during the course of a 1/4 mile (or 1/8 mile) drag race. This is normal.
Use of Bead Screws
If you elect to use bead screws, we recommend the installation of 16 equally spaced screws per bead.
Bead-Lock Wheels
For drag strip speeds in excess of 180 mph, Bead-lock wheels are highly recommended

I tried them at 32 and they felt pretty squirrely. I bumped them up to 36 and they felt much more stable. They still hooked good too, but I'm just a stock SLP 345HP M6. At the track I run 20 and they hook awesome. I tried 32psi at the track one run just to see what they'd do at street pressure. They sucked and I spun a lot. Dropped to 20psi and NO more spinning!

You must have nice smooth flat roads. Roads here are bumpy and rutted and the car tracks all over when I ran it at 32 on the street. If I pass someone and cut back over it feels like the car is on jello it rolls around so much. That's why I hate tires with soft sidewalls. My friend was with me the first time I went to the track with them on and he felt it wobble all over too. The car is bone stock suspension too.
