Hi all,
Sorry if I posted to wrong forum earlier, but I'm trying to figure out the best tire pressure for maximum tire wear for my 2013 Cayenne GTS w/ 21" wheels.

I've had the car for 6 months and it's been at 32/38 lb front/rear.
However, the door indicator was much higher - closer to 40/48.
Can those of you who have owned Cayennes for a while share your thoughts?
Thx in advance.
Patrick

 

I use 42 psi all around, 2013 GTS w/21" sport wheels

 

For max mileage - use the chart above and pick "Full Load" values. You may loose some comfort and handling using those settings though, but since you're looking specifically for maximum mileage I can only assume that's the priority.

 

I was always curious as to what constitutes a ‘part load’? Is that if your a single driver not carrying around a family most of the time?

 

I think that's a pretty accurate description. FULL LOAD is when SWMBO and I drive to California.. and back.. it's when nothing else will fit in the rear trunk part, and the back seats can't be seen.
