What Tire Pressure for Azenis RT-615?

35ish cold.  depends on the car (weight/camber/etc)  start at like 36 or so cold and check them again hot--don't want to get too much into the mid 40s.  if you are nice to them, you should last all weekend on a set.  just rotate them after day 1.  man, I miss the days of cheap azenis.  the perfect lemon tire 

We start at 30 cold in our '89 Prelude.  The trick is not to exceed 40 hot in our experience.

We ran 32psi cold on our BMW 2002 it is just under 200lbs. and a 50/50 ratio.
We had great handling and low wear, will probably get another race out of this set.

I have heard of bad things happening to that tire if over inflated.

We ran 42 PSI cold in our ~3000 pound Thunderbird. They did very well, the outside tire was blue at the tread edge but never showed any loss of grip. Those same tires are being used for A/X duty on a RX7.

We are starting at 36 PSI cold in our ~1700 pound Civic.

Yes.

And the new 615K's seem to work well up to about 42psi.
After the first stint check them.
If the track is hot, set them to 39-42.

On a light weight car, you can get 3-4 races out of six tires.
We ran two new tires on the front. Switched them side to side before Sunday and ran two race old rears.
We could run the car as is for another race and then move the front to the rear.

Have them mounted outside facing in if they show unusual shoulder wear.
They are directional for wet conditions only.

There is about 1/4 inch of rubber after the tires are bald before they cord.
As long as the track is dry, they are safe with no tread.

The strength of the tire is in the steel reinforced carcass, not the tread.

You should run 54 psi on the right side and 31 psi on the left since there are mostly left turns you want to even out the contact patch
