I have the Michelin's on my car at the moment, great in the dry, but cr@p in the wet. Buying Pirelli P Zero Corsa's next time on the recommendation of several people, including Silverline. Allegedly far superior in the wet! Dunlop's, I used on a previous car (EVO) and thought they were excellent. The problem is you can't get them for the 17" wheels, but I hear Dunlop are developing a tyre that will fit the Porsche in 2003... although that doesn't help you now! I used to drive to track days the same as you, but have decided to tow instead, this allows me to have two sets of wheels; one set with cut slicks (P0 Corsa's) and a second set with good road tyres for the wet. If you rely on the cut slick tyres then you will be stuffed if it rains while on track, and let's be realistic, with living in the UK it invariably does! Is having two sets an option for you? >> Edited by mark 964rsr on Monday 9th December 13:40 >> Edited by mark 964rsr on Monday 9th December 13:42

Well, I spun in the wet on Michelins, but then again I don't know how much they had to do with it, and how much was driver incompetence I will certainly change to PzeroCs at some point, and certainly watch my right foot in the wet a little more

But as its was wet Dom if you had the pilot cup's on, rather than road tyres, you would have spun off into another county, not just scared a few Badgers >> Edited by iguana on Monday 9th December 15:40

OK sounds like Pirellis now or next year Dunlops as well. Mark - yes, 2 sets of wheels is an option. Right now I have one set original mags + worn out Bridgestone front tyres + near new Bridgestone SO2 rears....if someone can point me at 2 new/newish SO2 fronts ( 205/50 ZR17) that at least keeps me going. Will then get some Cup1 wheels + Pirelli/Dunlop road legal cut slicks in 2003.

Following pulled off Rennlist, FYI. Mel Never used them, but the A032R is supposedly one of the better wet-weather track tires (but one of the worst dry-weather ones). They are ver noisy, if that matters to you. Another tire that I've used and liked, which is equally as good in the wet (and anecdotally slightly better in the dry) is the Toyo RA1, if you can get the size you need. The Michelin Pilot Sport Cup is almost as good as Hoosiers in the dry, yet when unshaven, very admirable in the wet. They're expensive though. No track tire deals well with standing water. However, driving home from the track (still shod with track tires), I went through a couple of very heavy downpours, once with the Pilot Sport Cups, and once with (well-worn) RA1's. In both cases, other "regular" cars were pulling off the freeway, the rain was so heavy. I kept going (albeit at a reduced pace), and couldn't really tell I wasn't on street tires. When it comes to true wet weather (it's raining, the track surface is wet and / or puddling) a good street tire is fine=2E I run a set of Bridgestone RE71 for rain tires=2E They work great=2E Just about any high performance tire would work great=2E If you want to use a track tire, a full tread depth Kumho, Yoko, or Toyo would work fine=2E Note that any running on dry pavement will quickly wear the tread down enough to make them useless for wet weather=2E A032 is a compromise tire. It goes without saying that a dry tire and a wet tire are different: the profile is different, the tread is different, the compound is different, the function is different. I've run A032, Kumhos with tread and etc compromise tires in the wet and my Yokohama AVS sport street tires are better in the rain. Comes rain, I change to streets and pick up the air pressure.

does anyone have any experience of above ? In particular Pirelli p Zero Corsa, Michelin Pilot Sport Cup, dunlop formula R DO1J ??? Seeing as 'tread depth' starts at about 5mm, and road legal minimum is about 2mm, er, just how much use could you get..... Car is a 964RS, driver gets (a bit) scared in the rain...!!, limited road use eg to/from track
