I going up to 33" tires on the stock 16 inch wheels. Does anyone know what psi I should be running? Thanks.

The door sticker on mine says 35psi. I run 38psi.

 

If you want to avoid TPMS warnings, 38PSI. If I go on a road trip, I up it to 40PSI.

 

Air em up until the ride gets to rough for you.. As long as they are LT you can go upto 50 on C, 65 on D, and upto 80 on E. The higher the pressure, the less rolling resistance=better mpg.. I run mine in the high 30's (I do mostly city driving, and the roads are horrible/rough around here), and like Doc stated, increase the pressure even more, for long road trips.

If they are P-metric, 35psi is the max load pressure.

 

If you really want the best wear/ride do the tried and tested chalk method to find out what psi is best for your particular vehicle. It may differ front to rear also.

I'd go into detail about the procedure but you can find about 10 youtube videos on how to properly complete the task.

 

FYI, I did the chalk test on my 2010 Alpha/Offroad. I came up with 37psi in the front and 36psi in the rear. I am running 38psi in both at least through the winter to keep my low tire light from coming on. I have no mods that would add any additional weight over stock. I am sure different packages and mods would make some difference.
