John Whalley Posted September 3, 2018 Share Posted September 3, 2018 Brian. Very interesting. Not surprised by your assessment of the PS4S wet performance; that ties in with a number of reviews. But your experience of track use in the dry suggests they may be little or no better than other 'N' rated tyres. The Michelin claim of 80% road, 20% track seems somewhat optimistic. I would rather rely on your view, based upon actual use of a Cayman, that 95% road 5% track is nearer the mark. Still no 'N' PS4S 19s, however. A bit odd as many 718s have 19inch wheels. I am sure you are also right about Cup 2s being the best for dry tracks. Not sure I could justify another complete set of wheels and tyres. It is a bit wet around here to consider using Cup 2s for all uses, all year around. Link to comment Share on other sites More sharing options...
John Whalley Posted September 3, 2018 Share Posted September 3, 2018 Maybe I recall that there are 35 section PS4S 19 inch N tyres, but not 40 section? Link to comment Share on other sites More sharing options...
Highland Fling Posted September 3, 2018 Author Share Posted September 3, 2018 If I still have my 718 CS when the warranty expires, I'll fit a set of Michelin Cup 2's in place of the PS4S N0's. I need to go up a section width on the front sizes to 245, so that's why I'm not fitting Cup 2's as yet. Like you, I also cannot justify another set of wheels and tyres for my 718. My 718 is not a daily driver. It's used mainly for touring and occasional track days in the summer months. In winter it is in the garage resting, so permanent Cup 2's are a realistic option for me to consider. Brian Link to comment Share on other sites More sharing options...
