Tire pressures in 992

[blueline]

Thanks Tim. The manual: who would have thought to look there. I'll have to go back and look again -- I was right in that area of the menu and couldn't find it.

To add to the confusion, the pdf version of the manual has a glaring edit error/typo - instead of the 2nd selectable box reading "Standard Pressure" it says the same as the first one, "Comfort pressure". However, the sub-heading is correct: "Standard pressure is activated". (I need to look at the hard copy and see if it has the same error.)

When I received my 992 carrera in May the tire pressures were front/rear 40/48 cold. I initially trust my dealership and didn't second guess this until the road noise got to me and I read my manual. Quickly dropped them to 30/36 (weather 60-80F, bay area) and reset the sensors. Big improvement in comfort but looking for advice from others.

Where does everyone else keep their tires pressures? Do you change it for track or spirited drives?

On my GTS the door jam says that the F are 35 and R 47, which I though was too high but I went ahead and made them that way. So I had my break in oil change, because I wanted to and the tech said that my pressure was too high so he changed them. He said that for my car it should be F 33 and R 36.

Eric,

I have a '22 Carrera GTS Cabriolet. Unless you believe that "one size fits all", I find the door-jam information is only to be used in emergencies, such as when you can't refer to the manual. In my (our) manual there is an excellent Tire Pressure table that begins on page 330. In the grey-shaded area you can find the exact description of your car (for example GTS) and the white rows will describe your particular tire and wheel sizes (summer/winter and 19/20 or 20/21). You will see that the standard suggestion for partial loads (typical circumstance) our GTS's is F 33 and R 39. HOWEVER, if you turn one more page, to page 332, you will see "comfort" settings for our car of F 29 and R 32. There is a world of difference in ride & handling characteristics between F 29 R 32 and the door jam suggestion of F35 and R 47, so you can experiment with what feels right to you, but the table in the manual is a much better source of information than the door jam sticker. My personal preference, with summer tires, is for the comfort settings or just a little harder, so I use F30 R33.
