Best Tires for the Ford Focus ST 2.3 Ecoboost Estate (Mk4)

Comparing this tire to Michelin PS4S and Goodyear SuperSport.
CS7 is superior to both in wet grip, which is just phenomenal! Miles better than GY SS and also better than PS4S.
They don't need heat in them to grip, which is also a big advantage. Good dry grip, predictable, good comfort, etc.

I drive very fast and up until a month ago, I thought that this is the best tire you could buy. I still think this is the case for most people, just not for me.

When you drive really fast on the road (and I mean fast in the way that lands you in jail in most countries), they disintegrate. Mine started peeling after 20km of pushing on a closed road.
I then took them to a trackday, put them on the back of the car, because it was raining, and they were great, while it was wet. As soon as it dried out, the outer edge of the tire was gone in one lap, just delaminated. Mind you, this was on the back on a FWD car, I had GY SS on the front and they were as new.

So if you drive fast most of the time, buy GY SS. If you need a tire that is phenomenal in wet and dry and you don't push the car to the limits, just get the CS7, it really is that good.

Big wheel sizes prefer full winter tires to All-Season but if you live like I do in a mild climate such as the Southeast of England, they often are the best choice. Divided between the new Continental All-Season or the Bridgestone WeatherControl Evo, I went to the latter as they were available and nicely priced for the size I needed. Pros: - Steering feel and road feedback are excellent for a all-season tire that has loads of tread blocks. - Impressive shallow water grip at low temperatures (looses a bit as they get up but not terrible). - Comfortable and relative low noise - Overall feeling is quite good and could be at times be perceived as a mid range summer tire rather than an All-Season Cons: - Wear far too quickly. I don't believe they would last 20k miles or get to see the second year of ownership if used all year round. - Again, wear. As temperatures start to go up they generate far too much heat and with a soft sidewall you can see the changes on dry grip happening and the wear marks on it - expect to see bits of rubber literally coming out! - Ice and snow grip isn't on par with the best of new all season tires. Be mindful that for locations that see little snow this might not be an issue, but when it falls and quickly gets compressed, they might let you down. Conclusion: - They are not the best out there but quite satisfactory on this large size; - For fast cars on mild climates they retain quite good stirring feeling and feedback; - They are excellent in the rain with low temperatures, and while aquaplaning resistance isn't the best, it has never been an issue; - They wear far too quickly for an all season tire, having only encountered similar wear on full winters driven in warm summer locations. - Fairly priced.
