My 997 C4 came with PS2's - the rears lasted about 8K miles - new ones were over $300 each - $400 installed. I replaced them with Kumho Ecsta's and couldn't be happier. Also, just read the Car and Driver tire review - turns out Kumho and a couple of others beat the PS2's as far as handling, road noise, and wet grip are concerned. These cars go thru rear tires too fast to be making a huge investment - for me, twice a year. I figure if I buy a set that I don't like, I will wait 6 months and try something different.

I have also heard good things about the Kumho Ecstas. I was told these are super sticky for track use, so I can imagine they are more that adequate for street use.

I made a quick excel sheet. As you may have guessed, there isn't a black and white decision but a gradient of options. All the tires listed are great performers to start with - we're talking about a few rarefied contenders, so it's hard to go wrong here.




Note: "Test Result" is the score obtained by Tire Rack's test method. Check them for test related details if you must ...

Result:
1. There are several tires out there which now out-perform the PS2. This isn't a surprise - the PS2's been holding the crown for a while.
2. Surprise: There are a few tires that out-perform the PS2 for less money.
3. Surprise: Some tires offer near-PS2 performance for FAR less money.

What about ride/road noise. My OE Continentals are loud and rough. I would like softer and quieter,even at the expense of performance.

TireRack test results weigh in the wet performance, dry performance, ride quality and road noise all together. So the 'good' tires already factor that in ..

If you rate noise above everything else while staying within the 911 realm, I'd suggest you pick some of the few good rated tires and see the detailed report.

eg. The Dunlop Direzza Sport Z1 Star Spec

This one has good noise comfort as does the Yokohama I put in the above table. I'm inclined to stay away from the Kumho given their rather poor wet performance.

I don't see 295/30-19 in Kumho Ecsta XS nor 235/35-19
Am I missing something or did they discontinued the size for 997S

Sids911, is there a reason why your table lists 17" tire sizes?

Me too. I bought a C2 rather than an S for the 18" rather than 19" wheels.

I put on a set of Yokohama all-season tires in the winter in case I get caught out in a unexpected snowstorm. They ride a bit better than the PS2's and are somewhat quieter, and just looking at them they will outlast a few sets of the Michelins. I believe I'll try a set of Bridgestones next summer.

i have a set of htr z II on my boxster and it was somewhere around $600. They handle like a dream, BUT they seem to hate rain. My *** was all over the place on a damp road. I don't drive it in the rain, so i don't know how bad it would be.

Anyone that would go to costco to have their tires mounted should be banned from this site permanently, as they clearly lack common sense and judgement!

Does anyone have any experience with the Toyo line? I'm running Toyo Proxes ll on my Cayenne Turbo (soon to be going toward a C4S) and find them to perform and wear well though noisy as they age...I suspect they all do.

I saw those tires just a couple days ago, nome of the reviews were bad but was not able to get any Porsche owners feedback. Please keep us updated from your experience.
I am not searching for a track tire but a decent weekend drive tire.

The tire info here is great and appreciated. Is there a tire that people are running in warm and cold weather (not necessarily snow or ice), but cooler overall.

I originally picked up Toyo Proxes for my Cayenne Turbo because the Michelin Diamaris were wearing like crazy and costing like crazy. The Toyos were used by a Swiss performance house to set an oval track speed record with a Cayenne Turbo. I figured how bad can they be. Toyo Proxes in 275/40/20 for $185 each versus $420 each for the Michelins. The Toyos were USA made and the Michelins were MEXICO made! I replaced the Proxes at 20K mi with the new design Proxes ll said to be less noisy. So far so good and thats haulin some weight !, (Cayenne as apposed to Carrera).

Banned from this site.......smacks of torture!
Do you really believe that the tire jockeys at your friendly neighborhood tire shop are vastly superior to those at Costco? Costco's workers experience and equipment are as good or better than most. Anyone who believes a Porsche requires a mechanical engineer to lift it and install tires should not be questioning the common sense and judgement of others.
