Ideal Tire Pressure
Hello All - I finally took the leap and traded in my beloved '13 Panamera GTS, and in its place, am the proud owner of a '16 63AMG-S. While I loved the Panny's performance, man o man, am I happy with the trade. Just love every aspect of this car. I have every conceivable option, but truly love the "Active Seats" the most.
My only complaint would be, and its small, that the "seat bolsters" are so pronounced, that I any form of aggressive driving, my elbows are always getting crammed up. Porsche really does have its sat ergonomics down to a science....they hold you in like no one's business, yet never interfere with the driving aspect. Oh well.
Anyway, Tire Pressure was a key aspect of the Panamera handling, like most sport sedans, so I was also curious what most experienced drivers here have been running. The gas filter has some odd combination of either 41/33 for my OEM 19's, which seems wacky. I have been running 38 front/ 34 rear, and seems to handle OK, but wondering if it could be improved. Ironically, the Panny also called for higher front over rear pressure, which is not that common. I ended up at 35/35 on that car for ideal handling/ performance. But, the Panny also was running on 20's.
Appreciate any thoughts anyone has.
Thanks!

Thanks...I'll try that this weekend and see the results. I still find it weird that the indicated "front" pressure is higher than the rear...just odd. Maybe it has to do with the weight of the engine, so they require higher pressure to offset this. Thanks

Agreed for sure...the ideal pressure is listed inside the gas cap...
my car indicates 41/33, which I still think is a bit high I switched to 39/35 (cold) over the weekend and I like it much better.

While there is info in the door, there are more specific recommendations inside the gas door that take into consideration, number of passengers (weight) and top speed. With 2 people in the car and speeds under 155mph, the recommended pressure is in the mid 30's with a slight variance front to rear. I don't remember the specifics off hand, but check it out. 51psi should be for the vehicle at max gross vehicle weight, way too high for day to day.
