35 psi on the stock wheels and tires. I would go 40 psi on an aftermarket setup.

Cause they are rated to higher PSI levels and have smaller side walls. Plus the more pressure you run the less inner tire wear you will have.

what does your TPM read when you start the car up and the tires are cold? do you start them at 35, or do you want to get to 35 once the tires warm up?

Tire pressures should always be measured adjusted cold.
