*991*

wow I picked up my 19 GTS from dealer and next day i saw on info screen my tire pressures were 60 psi on all four tires( I assume that is from transport to the dealer) I adjusted to the specs on the door jamb were 35 front rear 45 psi. The manual says even lower pressures than that
What pressures do u guys use for non track driving?

LexVan

Go 35 front and 38 rear. Cold. Adjust 1 psi up or down depending on your driving style. Rinse & repeat.

Brace yourself.

Tick the comfort setting in the tpms screen. Adjust to that.

rockrdude

yes, it will tell you the comfort setting. I believe it's 32 - 36

Greg D.

Go even lower IMO... 30-32.. Especially in this summer heat.

On 20" I run 31 f x 35 rear with 305's on the rear. Ride is perfect. Set partial load/comfort.

I always refer to the manual......

In my 991.2 Cabrio I use 30 in the front and 32 in the rear (comfort pressure).

Search this forum for tire pressure - we just had a thread recently but for some reason this topic comes up at least a month.

above lives all good advice

Comfort partial load is 29/33 for the .2 GTS. I usually run 2 psi higher and then readjust every month or so if pressure drops. I run the same for autocross.

It always shocks me that this discussion routinely leads to people recommending "comfort pressure." You own a state-of-the-art, iconic sports car and you're worried about comfort and how the road will treat you? I just don't get it. 2018 Targa 4 GTS, and I usually go with close to the higher end, as it states on the door jamb. I've tried the lower pressures and for me, it's too numb. It's my daily driver. But hey, to each his own.

You will get better grip with lower pressures than what is on the door. Why set it as hard as rocks for 165 mph + speeds if it isn’t necessary?

The types of roads one drives on most of the time matter as well. We have better than average roads in my area and I am running 35 front and 40 rear and when hot they are 38/42. I started out much lower, at 29/33, and worked up to where I am now. And the load is just 2 of us with a total weight of just under 300 lbs.

Yeah what he said. You just have to go into the "comfort setting" so that the stupid TPMS will stop giving needless warnings every time you start the car.

Ideal tire pressures are a function of the tire construction, and what provides maximum grip with one tire construction can be 20% +/- diifferent with another tire. Porsche should have provided a way to set a numerical value instead of the "comfort" mode that really has nothing to do with comfort.
