GT4 on Winter Tyres

[Terry]

Has anyone any experience of running their GT4 on winter tyres? I have a set of N rated winters that will fit and am undecided as to whether to have them put on.

I have a GT4 with two sets of OE wheels.

One set has the Michelin PSC2s for road and track (preferred to the Dunlops, on which fronts only lasted a day)

The other set has GY Eagle F1 AS2s for road use throughout the year - quieter, more compliant and more secure in the wet.

Michelin do Alpin 'winter tyres' for the GT4, but I'd be unlikely to use mine in such conditions

I have a spare set of wheels with Supersports fitted which make a huge difference.

For a start the tyre walls are less stiff and so the steering is much more feel-full in wet weather --- and then there is the extra grip in wet and cold weather.

In hot weather the Supersports will still pull 1.25g ... it's just that the PS2's will pull into 1.40g and I've seen over 1.55g in the compression at Eau-Rouge ...

And I worry about tyre shoulder wear

Wait and fit the ps4s. That will be the new benchmark tyre due out this month.

Been using mine frequently, including some cold, damp days. The Cup 2s are fine, the car is still fun and fast by most standards BUT you'd have to be foolish or very skilful to really push in such conditions as grip is limited and you cannot tell when it will let go. The traction control warning lights come on a fair bit and you can break traction at will in the first two gears with easy tail slides but if that happened at higher speeds it might be more than I could handle, I wouldn't like to find out.

Out of interest, Mr D, my newish 330d came with none run-flat MP Super Sports and my local tyre dealer said that they were the new 4s. Had a look and it just says MPSS so can't be sure. They have a very simple tread pattern unlike the Super Sports that I've seen before. Very good tyres, both grippy and offer a good ride, I'd put them on the GT4 when I need to replace the Cup 2s assuming they were Porsche approved, I'm sure they'd cope with a few trackdays as well as lots of road use.

That's not really a review, it's Michelin's claims in their launch PR.

They look a great replacement as an all round road tyre for the gt4 or other Porsche cars (really liked the ps2 I had on my 987spyder) and would be my first choice when the cup2s need replacing on my gt4!
