Thanks in advance...There is no label on the door..

 

In any and all vehicles you can use 32 to 34 PSI as the optimum tire air presuure. If you are concerned about ride, you can use 29 PSI with a slight degradation in MPG and handling.
Have a nice day, Bill

 

Thanks a lot for the response...BUT I want to know the recommended by the company...may be somebody has the company recommended label on its door who can tell me...Its a fact that every year we loose a lot on MPG on deflated tyres...I am currently using 30 psi on all four tyres...

 

The label on my 2009 Grand Marquise door jamb states 33psi for both front and rear tires, and 60psi for the spare. Tires are P225 60R17.

So, my original statement of 32 to 34 PSI is accurate for the Grand Marquise.

 

Thanks a lot mate for the information.

 

The tire pressure for most Grand Marquis models is 31 psi front, 35 psi rear.

 

Thanks laheer for the nice information...one question, if you can answer is that it is written on tyres that the maximum pressure is 36 psi...can I inflate that tyre to 35 psi?

thanks in advance.

 

tire size and pressure recommendations is located in passenger rear door if you open and look at where door latches on our cars

I would attach a picture but the site doesn't seem to allow it. The manufacturer recommends a PSI of 32 in the front and 35 in the rear. I found this in the rear passenger side door.
