Correct tyre pressures on GTS

[AW10]

umm, read the tyre pressure sticker?

what it says on the door card

33/36 hot for me. That equates to about 31/33 cold. On a 4wd car.

Does the TPM system not normalise for temperature?

Up to now around 30k Miles over a couple of 991.2 Targa 4GTSs. P-Zeros. I would go with 33 Psi Front and 36 Rear when cold, for what you have described.

Perfect thanks mate and comfort setting half load in tpms ?

Tbh, I would just stick with the above, Quite a bit of weight in the Targa 4GTS. In my experience the car feels more stable with the above PSI. I leave mine in sport chassis all the time, but that's just personal preference.

33F 36R cold pressures seem on the high side as i find the P zeros can easily go up to 42psi when driven very hard..The P zeros are OK until you up the ante, they basically don't like being cornered on the limit IME on my GTS and 981 Spyder..

Dont forget the Targa 4GTS has another 100kgs up on the Coupe. Also the PSIs that I have set out above are lower than what are recommend for 2 Up with full luggage. Have drove to Spain a few times 2 up with full luggage. Dont like it at high speeds like over 130s with lower PSIs than above. Also whist the Targa is great fun, its not really a car to drive on the limit like the GT3s and GTS coupes.

I am running 29 front and 32 rear when cold. It does feel a little skittish though and the traction light often comes on when accelerating over bumpy surfaces. It rides as though the pressures are far too high which does not inspire confidence. Does anyone else think this??

What tyres are you on? I run these pressures with MPS4S and it alleviated the skittish feeling I had running at the higher pressures most people on here seem to run.

I am on Pirelli’s at the moment but will defo change to Michelin at replacement time. It feels like I am running far too much psi but I am not when looking at what others run.

I run the comfort settings of 29FA and 33RA on Michelin PS4S on my 991.2 C4 GTS. I find it a much better ride than the standard.
