But note: I'm fanatical about tire pressures and correct alignment...the former is checked monthly and the latter is checked annually.
Leading evidence: 'Check annually' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check annually' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I will be using the same tires when these need changing.
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.

I passed by a vacant Discount Tire on my way to work today and decided to take the opportunity to get a health report on my 14 month old tires. (I purchased the tires when I bought the car.) They are
Bridgestone Potenza S-04 Pole Position
, and I'm really happy with them, for the record.
So I ask the guy in the bay how much it would cost to just pull them all off and take a look together. He says to me, "I've never driven a Porsche before so I'll do it for free!" I told him to take the long way in and drive it around the shopping center parking lot, and I'm sure you're not surprised that this put a huge grin on his face. I always appreciate the power this car has to make people happy! (For those wondering, he drove it like a grandmother... respectfully
)
So he says my alignment looks really good which is a relief, that was a saga in itself. But my surprise was that all 4 corners were 7/32 after about 5,500 miles. He informed me that the tires come at 9/32 so I was looking really good in his opinion. I'm not upset about this news... but I am a bit confused.
I searched for this and came up with tons of uneven, rear-biased, and inner-edge based topics. Nobody seems to be asking about even tire wear. From what I have read here it seems common for rear tires wearing approximately twice as fast as the fronts. At the very least, I was completely expecting the rears to be a point or 3 behind the fronts. Has anybody else come across this and I just don't read enough Rennlist? I definitely run the **** out of this car!
Thanks for reading!

I don't have any responses to your post but was happy to read that you are pleased with the S-04 tires since I just switched and put a new set of them on my car.
I have potensa all year round on mine. A good 15000 on them and still level wear all round and I drive the crap out of mine as well. That's why I have a cobra radar detector on board. I will be using the same tires when these need changing.
I'm definitely in the 2 sets of rears for every set of fronts club (Michelin's). I might even have gotten 3 sets of rears on Pirelli's if I hadn't run out of money. Must be all that sick-nasty drifting I do

Even wear?? That's failure mode 241! Engine must come out immediately!
Seriously, I go through to rears to a pair of fronts. I go through a pair of rear tires in about 12,000 kms (~7500 miles)
For the record...Porsche alignment specs call for a slight amount of negative camber, say 1.5-2 degrees, for street driven cars...more for track rats. This negative camber will increase slightly over time as the suspension settles.
As a result, even gently driven P-cars will exhibit more wear on the rear tires than the fronts. And BTW, hard straight line acceleration increases rear tire wear on C2s!
My beloved Mk 1 996 is basically gently driven most of the time. My rear tires typically last 20+K_ miles, and the fronts usually "age out" before wearing out. But note: I'm fanatical about tire pressures and correct alignment...the former is checked monthly and the latter is checked annually.

And the first 2/32" of wear will occur in fewer miles than the next 2/32". As tires wear, the amount of tread "squirm" decreases, with a corresponding reduction in tire wear.
