What is the correct tire pressure for a 2001 Pontiac Aztek if the inflation sticker is missing and it is not in the manual assume it either 30 or 35 PSI?

Check a tire retailer- they should have specs.

Also, you can check the side wall of the tire, and it will give you the max pressure for the tire. It is safe to add this amount of air, until you find out the proper inflation for your Aztek. Addition to answer: My 2001 Aztek has tires of two types, Eclipse and Bridgestone, and they say up to 44 psi. However, my manual says to look at the label on the rear edge of the driver's door. There it says 35 psi or 240 kpa both front and back. 60 psi for the spare.
