Posted by: sixaddict Jul 11 2012, 08:08 PM

Just installed new tires for DE this weekend...Need hot pressure recommendations for NT 01s
How much build up is typical (914-6 3 liter) if it matters.
Thanks

They are very similar to Toyo RA-1's.

Start between 26-28 cold and target mid to high 30's not to exceed 40psi.

If you go above 40, you will know.
It's like throwing a switch between driveable and not!

My RA1s would show hot centers at 34 hot. Granted this was AXing and not track time. Think I tried to keep them at 33 hot.

Thanks guys good start
As a side note for anyone loooking....
I had been running Hoosiers..and while I liked them this was a cost based decision.
Tires were set at 31 -32 cold and were going to 38-39. Changed to heavier front torsion bars ( 23) and tires went to 35....I broke so never started them higher but felt this told be car was workng better.

I'm running them on a 2.7l six. For circuit racing 24 cold will equate to 30 hot, which is about where you want to be. If you let them get up to 34-36 it will get very loose.

Mid '30s should be your target when hot for the track.

For AX, i like to start in the low '20s. Feels squiggly, but sticks better.
