You can not get the Michelin Super Sport in the original dimensions of a 993 turbo. At least not to the rear tires. The same problem occurs when looking at some of the later generations tires such as Bridgestone, which received good reviews.

Do we have any tire guru who plow through various types of tires that can provide some feedback?

I use Toyo R888 on track days and Bridgestone S03 on the street at the moment.

The options seem to be:

Continental Sport Contact 2 N2
Pirelli P Zero Assimetrico N4
Michelin Pilot Sport 2 N3
Bridgestone Potenza S02 N2
Bridgestone Potenza S02 N3 A

 

I just put on the Hankook V12. Coming of P-Zero Rosso's, and I have to say that for the money, they are great. They were a little rough in the corners for the first 500 miles, but just took them AX last weekend and felt great. On the street they are much quieter then P-Zero as well. And yes, they are not N rated, but that was not a factor for me.

Just one mans opinion...

Did I mention they were less then $700 for all 4.. If I hate them after one year. I'll move on to something else. So far they are great...

 

I have Nitto NT-05's on my street wheels, they are doing the job well. Also have heard good things about the Dunlap Direzza Sport Z1 Star Spec's.

 

I have the new Yokohama Advan Neova AD08's. Love them.

 

I just replaced the S03 on my C4S with Continental ExtremeContact DW. Cost was approx. $800 for the tires. Really like the ride, tread noise is low and seem to handle well for me. Tire Rack rated them number 1 in this test.

I think the new Michelin Super Sport is a really nice tire. The reviews are just telling you one thing, this is the next generation of tires, very nice. Depending on the width of your front rims, you might be able to fit the super sports. Not all sizes are N-rated but I don't think you have to swear by the N-rating. I was thinking like this:

Front 245/40/18 (works fine on 8,5" or wider front wheels)
Rear 285/35/18 (works fine on any rim 10" or larger. This particular size is available on the tirerack website)

With these sizes front and rear the rolling circumferance almost equal and even less difference F/R than the original setup. Both front and rear tires are taller tough, however that will affect the handling.. But people seem to run 275/35/18 so I don't see why 285/35/18 would work? The load rating looks okay too so I might give it a shot.

I think with these will you will be able to drive both on the street and on the track. I've yet to hear something negative about them. Wear is pretty good (almost like the PS2s), wet grip is good (also almost like the PS2s) but dry grip is almost as good as the MPSCs - e.g way faster than PS2s. Seems almost to good to be true if you ask me... Oh but then there is the price...

 

I didn't feel like paying $400 a piece for my rear tires, so I went with the Sumitomo HTR ZIII.

inexpensive, last ok, pretty good performance.

 

+1 on the Hankook V12. Installed them in the spring and for a street tire, love them.

 

Yes Viggo, it´s almost to good to be true. The Michelin Super Sport could be the perfect tire for someone like myself. The hollow spokes is 8" (front) and 10" (back) wide. If I could wait untill next year to buy new street tires, then maybe Michelin has more 18" sizes to choose from. But then again maybe not. I think many manufactures make tires for modern cars and most modern performance cars has 19" or even 20" sizes today.

In a way I think we are stuck with the "N" marked tires that I mentioned above. If we want modern tires we have to look elsewere at the moment.

The reason I choose R888 in the first place was that they had better wet abilites than the MPSC. Of the "N" marked street tires I mentioned. Which is the best on the track? I used the Bridgestone S02 (wrote wrong in my first post) during a trackday or two and they overheated of course. But are the Michelin Pilot Sport any better during the same condition or worse? Or any other street tires?

On the Nürburgring last year I used my street tires. My R888 would not have made the trip and truth to be told you really don´t need track tires on the ring. It´s more like a normal road than a track. Weather conditions can change quickly. Anytime it can rain on one part of the track and be dry in another part. The road surface is really slippery as soon as it rains.

 

+1 on the Hankooks, much better than the Sumitomos.

 

no they aren't.

Both are decent, neither is exemplary. There may be slight benefits to one or the other, but to say one is much better is ridiculous.

I've driven both, they are both fine.

I liked the kooks better in the rain, the sumis better in the dry.

 

I have bought many tires in the past, I'm on my second set of Dunlop Direzza star spec. I like them alot for the money I spent +-1000.00. They are OK in the wet, very responsive on the dry, I'm RS specs with neg camber, so they don't last long on the insides, I have done 12 000 miles with the front and 8 000 miles on the rears. I paid as little more than the Sumi or Hankooks, but I feel they are more silent and have a better grip. Just my 2 c.

TY

 

I am very happy with Pirelli P Zero Assimetrico N4.

 

On the Turbo I am running Kumho Ecsta SPT. 235/40/18 front and 295/30/18 rear. Been very happy so far. I don't drive in the rain, and the FabSpeed Bypass eliminates any tire noise.

My plan has always been to replace these with PS2's...but for the money and current performance, I just can't justify it. In the future, I'd like to get the new Michelin Super Sports in my sizes, if they become available.

I have PS2's on my Boxster, and they have been excellent.

 

Hankook or Sumitomo? Depends on what you want most out of the driving you do.

Mostly dry? Sumitomos still rock most IMO. Wet conditions? Most prefer the Hankooks if driving in a lot of water. The Hankooks are more "comfy", but that's because the tread is more open and the tires move a bit more movement under you at full tread depth.

Both run a touch skinny for their size.

Sumitomos have been a best seller for Porsche for years, and the Hankooks are gaining on them. If it were my car I'd buy Sumitomos.
