Is anybody running different tire pressures between the front and rear tires? I just picked up my 2015 Cayenne S CPO running on 295/35R21. Just noticed that the fronts are at 40 PSI while the rears are at 45 PSI. I assume the dealer did that on purpose?

Have you looked at the tire pressure sticker on the car (can't remember if it's on the door jamb or gas cap lid...)? It will tell you the recommended tire pressure. And yes, for the 958, recommended pressure is different front (lower) to rear (higher).

Yes. On most of the wheel/tire size setups for both the Cayenne and Macan models, tire pressures are different front and rear, rear being higher. Look at the chart in the owner's manual.

I have been running 44F and 49 R. I think the recommendation is 33F/39R with no load. 20" wheels, Pirelli Verde Plus A/S tires.

So what is pressures recommended for All Season 21" tires?

What is no load? (1 person or just no cargo or no towing)?

I'm in the office right now so I can't recall the details. If you check the owner's manual it defines partial versus full load in the context of tire pressures. The chart in the manual provides tire pressure specs for the different tire/wheel combos for both partial and full loads.

I run the 21 inch tires too and the factory recommendation is 38 front, 44 rear. It's on the sticker in the driver's door jamb too. I had a nail in my tire this morning and had it repaired so the settings is fresh in my mind. Now, if you look in the owner's manual, you'll see two different settings. One for normal driving and another for "comfort" driving. If you decide to lower the front and rear pressure for comfort, you have to go into the instrument cluster display and change the setting to "comfort" so the system knows you're now under pressured. But be careful to change it back to normal PSI settings if you're going to drive in excess of the "comfort" speed limits for long periods of time.
