I just thought that I would give a quick review of the aforementioned tyres.
I have had them on the car now for approximately 600 miles and they replaced my previous favourites, Goodyear Eagle F1 GSD 3.
All I can say is that the improvement from the Goodyears is remarkable. The dry grip and wet grip is noteably improved as well as reduced road noise. These tyres allow you to corner much faster and the bite is very pronounced. Overall the tyres have greatly improved the handling characterstics of the car, to the extent that it actually feels like a different car altogether! Another important factor, after going through 2 sets of the Goodyear's is that the Michelin's are rated to last a lot longer. The GSD3's really wear out fast due to their softer compound. In relation to this, I've found that tyre manufacturers have now managed to make newer premium sport tyres last longer on .
I would highly recommend these tyres on the MK4 Golf, especially on one like mine, GTI AGU 1.8T. My tyre size is 205/55 R16.
I also drive a Subaru and have observed that a certain brand of tyre will perform differently accross varying car makes. The Goodyears are undoubtebly the best tyres on a Subaru, but IMHO, the Michelins are better for a MK4 Golf.
