Optimal tire pressure for Pirelli CN36?

I recently upgraded my tires to Pirelli CN36s. They’re mounted on to Alpina 14s. I love the look but I am noticing some squealing on corners during “spirited” driving. I checked the tire pressure and it was roughly where I set it at 24 psi. Anyone out there running CN36s have any suggestions for the optimal pressure, and do you experience this problem? Thanks!
 
Proper inflation as indicated in the manual is 29-32psi, but track pressure (or for "spirited" driving) should be 34-36psi. They'll still squeal... that's the sound of happy tires.

Love CN36's too, they look and feel right with excellent all-around performance. One of the best choices available.

Remember when the Ford Explorer had numerous Firestone severe tire failure accidents back in the early '90's? Buyers were getting their first ladder frame truck and Ford wanted them to have a nice car-like soft ride. The door jamb said to inflate the 235/75/R15 tires to 23 lb's. That's why the tires failed. My '96 V8 Explorer had the tires inflated to 33 lb rear and 35 lbs front to compensate for the heavy front-end understeer. I drove that truck for 25 years and over 250K miles without any tire problems.

Click to expand...

24psi is 1,6 bar, that is very low pressure

2,5 bar front, 2,2 bar rear works for me
 
Can you folks share advice on where you're sourcing this tire from? I may need a new set soon, and it looks like CN36s are a foreign object with my usual retailers...

Thanks!
 
Not sure if this goes for a Coupe, but in the 2002 it was always recommended to run 2psi more in front than in back to help with understeer. (Like Drew was doing in his Explorer).

I know it really is noticeable on my 2002. I do the same for my 2000CS when I know we are going to play in the twisties.

The CN36s are pretty sticky. That same advice above was to increase the fronts until they became too “slippery”, then back off 2 psi. If you play the same routine on the rear, you will find a certain pressure that feels just right (everyone’s driving style and car is set up completely different).

That’s all worked well for me...

I met the Longstone guys at a show a few years back, they were great.
Every visitor when I was there was offered a proper pint glass, with a handle, and real ale to go in it. How good is that?
For the other nationalities this translate to
Old fashioned mug with warm, funny dark beer in it
