Would like to seek experience fellow car enthusiasts that use UUHP/Max Performance/semi-slick/daily worthy trackday tire, how's the wear like if the tyres barely hit working temperature?
Especially whoever run SC6, PSS, PS4S, Potenza S007A, Potenza Sport, Eagle F1 SuperSport, P Zero Corsa etc, the experience should be closer, but those more hardcore are welcome too.

I have installed Continental SC7 about 2 months ago, and clocked 1500km.

I'm puzzled by how little is the wear, especially both rear tyres shown barely use.
Even the air release hole mark of the mold is still on the thread.

1500km is supposedly 7.5% of tread life, if I use 20,000km as my benchmark.
- consider my last tyre Continental PC6 only lasted 20,000km (tread can push for 30,000km but I switch early due to uneven outer wear, and rubber stiffen).
- consider SC7 is on even softer compound than PC6.

On the usage
- I did mostly short 10-20km trip, I guess as soon as it fully warm up the trip end.
- For the record the grip already exceeded PC6 within 1-2 corners, no need warm up for daily drive.
- Car has eAWD. Short trip EV mode is RWD. Long distance hybrid mode is front bias AWD.

If this trend continue, I think SC7 will outlast PC6 by large margin. My itchy hands might swap to new PSS5 when it releases before current set done deal.
Good thing is I'll have 2 set of rim when my 7.5kg 19" arrives next year. What a long lead time.

Rear - the release hole mark still like new, like barely used.

Front - very light release hole mark, almost gone.

read up tire cold tears laugh.gif

for stickier tire compounds, you're still getting similar wears on cold as hot, just that they are being pointlessly wasted when not bringing up to temperature fulfilling their intended use and potential.

Thanks. Learned new term. I'm not getting that, guess due to not pushing usage on the street.

From what you shared, I can't explain the current wear pattern. Hard to believe the molding marks are still there after 1500km, expect those to be gone in 200km. Lol

Unless I gotta attribute that to less slippage due to higher grip.
Like Porshe claims 992 GT3 RS has whopping 30% slower wear than 992 GT3 due to significant less tyre slip given high downforce.

If this is true, meaning the OEM selected tyre category has insufficent grip to handle the car torque and weight. To a point all fat heavy super saloon, SUV, and EV should use high grip tyres.

Most super saloons (Audi RS, Panamera, E63s AMG, etc) have UUHP from factory, whuch is the right tyre to use.

I wouldn't pay attention to the marks. Less slippage aside, stiffer tires resulting less flex and less outer wear is also a contributing factor.

And OEM selected tires?
Consider cost and priorities to the majority of owners.

Even super cars Sport cars, do you think most owners even able to even utilise any where remotely close to the car potential?

I'll just leave you with this - willing to spend 35k on Brembo upgrades, drive Porsche badge.
But the only thing contacting the ground and vehicle... Lol

Hang on... that familiar beacon light on the top left corner, is that a Civic?

Anyway, not that my main intention is to look at the marks, sooner or later they will be gone even with lower than expected wear. Itchy hands thinking of a potential project. Lol

Don't know man, very hard to relate anything in this picture to Porsche.

Even the Porsche crest and Brembo looks fake with that tire on tongue.gif

best way to increase tyre temperature is heavvy brake straight line. just a few times enough

Civic/86 put Cup2 tire and take picture at similar angle. I will yell "Is that a GT4 RS?" tongue.gif
