Default M/T Drag radials -- What air psi for the street?

Bought some of those new m/t drag radials for the street. Just wondering how much air to run in them for the street.

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!

15-16 psi. If you think it feels squirrely at 32 psi, something is wrong with your car.

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.

I think they feel great, but then again I drove on ET streets (non-drag radial) for a couple years, if you think the DR's feel loose you'd wet yourself on those.
