If you need summer only then sumitomo's HTR ZIIIs but if you need an all weather tire, the best are continental DWS (Dry Wet Snow)

 

I would agree if you're on a budget or just street cruising. The DWS though only does ok on very light snow in my experience but I was very surprised by its wet weather performance. You may experience noise issues with the Sumi's as they wear. I'm not sure if they resolved this issue or not.

Currently on Hankook V12's and I know they have a newer version out but the older version was pretty decent for me for the price.

However if you have the budget and/or are very sensitive or finicky, I would recommend the Michelins. They don't excel at any one thing but they are very good in all categories and very refined. This level of refinement is what you're mainly paying the extra for IMO. And refinement really matters to some, especially on the streets. On the opposite end of the spectrum, if you have poly mounts and stiff coilovers, get the Star Specs. :devil:

I agree with the Sumi HTR ZIIIs choice. I have Blizzaks for the cold months, so I switch sets back and forth. So far my Sumis are quiet and perform well enough for me and my C2.

 

Here's another vote for Continentals.
I run DWS tires on my 2001 C4 and DW tires on my Cayman.
Quiet, excellent wet traction, and enough dry traction and responsiveness for the street driving (sometimes spirited) that I do.

 

I just got the new version of the Hankook V12's for my rears. Front Hankooks were still good at 12K miles. I like them, they are quiet and smooth riding. Minimal road noise in my cab.

Good luck.

 

If you don't mind paying high price, get the Pilot.

On the other end, get the Hankook for the same performance but half the price.

 

Skip the Hankook V12s; you're driving a Porsche, you know- get the Hankook R-S3! For real, the R-S3 v2 is a fantastic tire, Hankook's best street tire, and sits in a performance category above the V12 and PS2/PSS.

 

Interesting. Are these new? I don't remember seeing them when I bought mine.

Just a FYI, I find it cool/funny/ironic that the official tire of the DTM German race series is the Korean Hankook but that also says something about the company as well.

 

The R-S3 is a relatively new tire, but it's been around about 3 years now. It has a new compound for this year (tirerack's calling it the "v2" though you can only tell by the date stamp) which gives better cold-weather performance than the "v1", but it's one of the best performing 200+ treadwear street tire on the market right now.

Dunlop ZII* and BFG Rival are the other top tires; each of the 3 taking top honors in different tests; lot of variables involved, but all the top GT3s were running R-S3 at the SCCA autocross national championships this year.

 

+1 on the sumis - I also ran them around Laguna seca - no problems - I was more of a limit than my tires were .... Perhaps not for an experienced gt3 driver but perfect for everyday at US highway speeds ...

 

What size are you running? I don't see tirerack or discounttiredirect offering the R-S3 in the OEM sizes for my 996 (18" oem option)

 

Don't limit yourself to OEM sizes; go wider in the front and dial out some of that understeer- just make sure you keep rake the same so it doesn't interfere with PSM/ABS. Go as wide as you can on both ends, really.

I'm running 255/35-18 & 275/35-18 ZII on my 2010 Boxster S; R-S3 v2 are available in these sizes as well. That's 20mm wider than (my) OEM in the front, 10mm wider in the back, and slightly shorter than the OEM tires.

 

The V12's are probably adequate - ore more than adequate - for the original poster's request for "everyday driving" tires...

 

How much is the RS 3

 

I had the Sumi HTR ZIII on my Honda S2000 and had no issues. On my 911 however they are unbearably loud. At freeway speeds the noise level is ridiculous. My next set of tires will likely be Hankook V12's which I currently have on my BMW 328XiT
