Hey guys,
I have the 20" P-Zeros. For the "Standard Partly Loaded" the manual suggests 31F and 37R. Does this seem to work for around town driving with just me in the car?
Thanks

Jeez that seems awfully low, I saw that in the owners manual. I don't mind a firmer ride at all. I'm basically looking for that perfect PSI for handling, tire life and ride. Comfort partly loaded (29/31) and the door jamb setting of (35/45) seem far apart and something must suffer on either of those settings...more than likely tire wear on both ends of the spectrum.
What do you run Hurricane?

The one on the door jam is for driving in excess of 165 mph. Lots of dealers will send cars off with that pressure and it is like driving on rocks.

Comfort, partial load is 29/33 for the 991.2GTS - I usually run about 2 psi higher or close to that, depending on temperatures and loss of pressure over time, but never under. I usually run the same for autocross.

What do you suggest for maximum grip off a launch and best psi for FULL LOAD.
No more comfort talk!

A full load is passengers all around and a full frunk. I am running 245 f and 305 r and I set at 31 f x 35 r. No need to run high pressure for street driving. Car will misbehave.

Would cold pressures of 33f/36r be safe for 160mph+?

In cold temps, since I usually add 2 psi, I am pretty close to 29/33 as a cold temp. If lower than that, I will add more air.

The 31/37 is in the owner's manual
