Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi All I've read a lot about the need to keep a watch on the tyre pressures as the car can handle very differently due to minimal differences in tyre pressure. What pressure F/R should I be running? I have searched the forum with little joy. I do not have a GT3 but I do have the GT3 Aerokit and therefore the wheels - thought you may be the best people to ask. Cheers Beno

POST 2Original post

Porsche recomends 36 lbs front, 44 lbs rear for 18" wheels. That's what I run on my 996 C4S.

POST 3Original post

Watch your tire wear. After a thousand miles, see what's going on with the factory pressures. If you notice problems, you can drop a couple pounds too, and then see how they wear. Also, if you have really bad roads or find the ride too harsh, you can probably drop pressures by 5% all the way around.

POST 5Original post

After some experimenting, I settled down on 35/39 on my C4S. Pilot Sport N1, Stock alignment/tires.

POST 6Original post

36front/44rear.. gone +250km/hr for over 20minutes and reached 280+km/hr for a few minutes.. no problem! Waz

POST 7Original post

For 18" Rossos I have found that 32/39 f/r cold pressures end up at 36/44 after hot laps.

POST 8Original post

Ambient pressures at 36/44 works pretty well on the street, or you can try the stock Gt3 specs (34/39). On the track I aim for 36/44 hot as well.

This is a source reference. Confirm exact model applicability in the original material.
