GT4 tyres

[burman]

Any thoughts on current N rated road tyres for GT4 ( both 981 and 718) other than Cup2s as I am an all year round driver. I see Michelin has a new 5s out but probably not N rated.

PS4Ss are available in N spec.

Totally recommended.

I fitted PS4S to my GT4 to make it more useable in spring and autumn but it really took away the sharpness of the handling.
It felt a bit like driving on winters all year round, but I guess that's the compromise you make.

If I were to do it again, I'd get 2nd set of wheels with PS4S for the colder months, probably 19".

Yep, the softer tyre walls do affect the feel but the bonus is that heat up quickly and stay warmer in cold and wet weather.

I use PS4Ss as winters!

PS5S not available yet in our sizes or rating hopefully soonish….

I went PS4S, just couldn’t get heat into the Cups at all, I only do a few track days a year so 95% is road driving and I have found the 4S to be a better tyre in that situation, tracking them is only an issue if you want to do more than 10 laps in a stint and they go squidgy.

I’ve still got my cups so gonna buy a set of track wheels for them and then they’ll only be used for the track. Still prefer the 4S in summer as a road tyre, I like the softer sidewall as the suspension is always set to firm unless I’m going to the shops or on the motorway and it’s a great combination for me personally.

I’ve used Cup1 &2 for 15 years on 911s and they were perfect, just don’t like them on the GT4 in anything but a hot dry day.

I found PS4S's great on my 981 GT4 although the handling does feel a little sharper on Cup 2s.

The convenience of not having to worry about rain and temperature with PS4S's on the road is worth it though IMO.

Thanks for confirming that Twinfan, my car had an ageing set of Cup 2s on when I bought it a year ago and I ran them all last year. The last owner also kindly supplied a nearly new set of P4s as part of the deal, but they are non N rated but fine as I rarely go over 140 on the public road ! I intend to stick to them when changing but will then get N rated .

No worries
