My GTS feels a lot less grippy recently. The back end is much easier to get out even at relatively normal speeds. I've checked tyre pressures and they're ok, tracking seems fine......could this just be down to the cold weather? Not so long ago you could go out in a t-shirt, now it's about 9 degrees out....so the rubber will be cold, the roads will be cold, and those two factors will make it much less grippy.

Anyone any other view? Just the cold?

I am spinning all 4 wheels for a split second when I change to 2nd gear so not much grip about :-)

I'd go with "just the cold" too.

As I recall, conventional wisdom suggests that winter tyres, with their softer compound, start winning over regular tyres when the temperature gets to around +7c.

Hopefully somebody more knowledgable than me will come along with actual facts, but I wouldn't be at all surprised to hear that regular tyres become less grippy somewhat before that.

I'd say it's the cold too. Just put winter tyres on the A class and it has made a difference in terms of grip even though ambient temperatures are still above 7•C.

No problem with grip from tyres on Monday at track day though wink

I have to say I normally experience this on most cars due to the fact its obviously colder.

However I have to say kudos to Michelin as the Super Sports are just unreal, no real loss of grip even on the colder sub 5c wet mornings we've seen recently, the grip on offer is simply unreal for the road conditions. The Super Sports really are impressive and shall be interesting to see how they cope in near freezing conditions, obviously in snow they shall be pap. My point is most Summer tyres really tend to perform far less when temps drop to single digits on cold wet mornings, wheras the Supersports I've so far not witnessed this, very very impressed by them. smile

My experience is that while 7c is the optimum, the PS2s grip fine for normal road use down to about 3 degrees. This is during the daytime though, at night you tend to feel it alot more on greasy roads.

Like as mentioned on the winter tyre thread, just because the car will go does not mean you can stop, I think it is more of a problem on a 911 than on a 987 due to the extra weight and distribution of that weight.

Get winter tyres fitted.

Pilot Sports on the back of my little Boxster gave me two big sideways moments on Sunday afternoon... Coupla 50p/20p moments, and some opposite lock straightened things out fortunately. They are getting a bit low on tread mind, new tyres have been delivered this morning.
