I usually run about 2psi higher than is stated on the door, as long as it doesn't go over the max rating on the tire. I think mine recommends 32psi, and I put in 34psi. Not sure why, but that's just what I use as a rule of thumb.

always use the pressure thats listed on the TIRE! the door jamb does not know if the tires have been replaced!
Wrong!
Gotta be smarter than the tire I guess, lol.
The only psi you will see on the tire is the MAX pressure the tire should ever be inflated to.
NOT the vehicles recommended pressure.
The owner better know if the tires have been changed with a different size, or load index rating.
If you stray from OE sizing, you better know what pressure you should run, and hint, its NEVER on the tire.
The only psi you will see on the tire is the MAX pressure the tire should ever be inflated to. NOT the vehicles recommended pressure.
I think the Pirellis that came stock with mine have a max pressure of 50psi. I think that would have about the same ride as the Fred Flintstone mobile at 50psi!
I was always told to use 35psi if there wasn't any other reference.

from a guy named stoenr..........you still didn't answer his question. what p.s.i.? just guess?
Hey now, no name calling . 19 years, still working for Goodyear,
I have retained some of my knowledge, I think.....
The answer has been given, door sill placard is what you should go by, unless tire size has been altered.
