I have the 19" factory rims with the Conti tires

The rear tires have about 10% tread left and the fronts 30% (I am waiting for a set of back-ordered PS2's to come in).

NO rain driving
NO passengers
Outside So. CA temps right now are around 70 to 80 degrees

I am looking for maximum cornering ability and minimized under-steer.

Thanks for the help!!!
Weird question...

As far as the stock Contis, as well as stock suspension setup...Look inside the driver's side door..BUT, with 10% tread(rears)...I would deflate them to 10psi less than what's on the sticker..Or replace them quickly(they go fast, once signs of good wear)...As far as the fronts, swap left from right..

If the car is stock on all suspension components...It's a good idea to keep the understeer..The car has been tried and tested for those tires and tow/camber...Despite the overwhelming tilt/lean, the car actually will pull nicely out of corners with a stock setup..But you need to specify, not temps of SoCal, but what you are trying to do with the car...You might need something more than tire PSI....$$$
