Default PSI question

What PSI do you run on street tires and DR. Just got Nittos. Shop told me to run 40... But GM says 30. What do you suggest?


Got regular streets upfront, 555r in the back.

30-35 is what I use.

You'll want to drop the Nittos down some when you really want to play from what I've heard.
