LargentThe factory specs say to inflate the original runflats to 28 psi.

But now, I'm ruining the Falken Azenis tires.

The Falken tires state the max pressure is 50 psi.

Hmmmm - 28 psi or 50 psi or something in-between...

What is the recommendation for non-original tires?

ed monahanI would say go with the sidewall on the tire. Whatever they recommend.
TucsonJerThe 50 lbs. is a maximum pressure. Most dealers use 34 lbs. as a standard. Hope that helps. Jer
jimsuttonI have the Falken tires and run 35 lbs. in them never had a problem
georgieboyThe tire pressure printed on tires is not the recommended pressure but a maximum pressure not to be exceeded. The pressure recommended by Chrysler is the pressure to use on all tires of that size. The front and rear tires have a different recommended pressure being different size tires.

I hear ya -
It just seems that tires with different sidewall construction (hard vs soft - able to support the weight of the vehicle vs not) would require different pressure.

This is why I'm asking...

padrooThat 50 lbs. Written on the sidewall of the tire is a maximum safe pressure the tire should never excede. The tire should be inflated to the numbers written on the drivers door opening.
The fronts are 28 psi and the rears are 32psi. I am assuming you are running stock size tires.

LargentYes - I am running stock size tires.
VinceMMy door sticker says 28 PSI for both front and rear tires as does the owners manual on page 101.
LargentVince -
This is Richard from the So Cal Prowlers group.
I'm the one with the Woodward.

My door and manual also state a single value of 28 lbs.
That being said; we still have the prevailing question -
To inflate at or near the Max value listed on the tire OR stick with what the door says no matter what kind of tire you've put on the car (as long as it's the same size as original).

enzvoyOn newer cars, the recommended pressure is most commonly listed on a sticker inside the driver's door. If there's no sticker on the door, you can usually find the specs in the owner's manual. Most passenger cars will recommend 32 to 35 psi in the tires when they're cold

LSKI run the Continental Extreme Contact DWS tires front and rear. I keep 28 pounds (cold) in all 4 tires. I had my oil change place put 35 pounds in them one day and I thought I was going to bounce off the road before I lowered the air pressure. My TPM's don't work anymore (a small piece of black tape covers the dashboard idiot light), so I carry a good air pressure gauge in the glove compartment. Usually check them on Saturday every week. I always do a walk around anytime I leave home to make sure none of the tires have lost air. I like these tires and have never had a problem with them loosing grip on the road.
Richnew41Hey LSK... Why not just replace tpm in the tires...
Got to be better than black tape look... You could always pull the dash and remove the bulb... Takes just a minute...
VinceMI think the question about inflating close to the max psi listed on the sidewall has been answered well. I believe the engineers that designed the suspension came up with 28 psi for handling, ride and safety. You can run higher psi than recommended but one or more of the 3 items I listed may be affected.
mslc10I run lower pressure for a softer ride.

Agreed - thanks for the help
