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.

I run 33F and 37R cold, when they get hot this can go as high as 38f and 41R.

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.

10 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 · 1 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

Hello all. I have Michelin Pilot Sport 4S, 225/40 ZR 18 and 295/30 ZR 18. I consider myself a "gentleman driver"...occasional spirited driving when conditions permit. Looking to maximize tread wear. Owner's manual seems to list maximum tire pressures (?) for C4, no entry for C4S..... Thanks for the input. Scott Bee

POST 2Original post

If all you want to know is the max recommended front/rear tire pressures, just read the label inside the gas cap door. Many people here run a few pounds lower though, but you can search for those discussions.

POST 3Original post

I'm running 34f 40r in my 05 C4S. The lesser pressure takes a little of the teeth rattle out of the S suspension with no noticeable additional tire wear impact. This was recommended to me years ago by a very knowledgeable RL member.

POST 4Original post

Fuel door cap says 36f 44r and have always ran with that. Going to give 34f and 40f a try.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the info. I'll give it a try.

POST 6Original post

32/40 in my TT. Agree with Wildbilly on the more comfortable ride than the recommended 34/44 with X73 suspension.

POST 7Original post

Good to know, I�ve been running the recommended 36F / 44R. I�ll adjust to 34/40 and look forward to the �softer� ride. Thanks!

34f 40r has been working on my05 C4S(AWD) since 2015 with no weird/premature thread wear.

POST 9Original post

Alignment can induce the need to adjust tire pressure, Tire age... etc.. I usually bump +/- by 2 lbs at a time till I find what the setup likes.

POST 10Original post

C4 here, but same pressures recommended. For some reason Porsche only list the pressures for doing autobahn speeds and a full load, so they are very high. I run 33F and 37R cold, when they get hot this can go as high as 38f and 41R. This gives far more bite on road surfaces that are not pool table smooth and makes them far more comfy when wafting around. The max pressures of 36F and 44R ruin the handling and the ride quality imho.
