Had the tyres on all four wheels for a few weeks now, and had a four wheel alignment done, so I feel I can speak with some insight. Honestly, probably not quite what I expected, given the various test results. Feel, feedback and communication are absolutely top notch. Can't fault them in these respects. What slightly surprises me is that they don't seem all that grippy. Dry grip is OK. Wet grip is slightly weak. Now, I will add one caveat here. The 130i in rare SE spec has two allowable tyre size options as standard: either 205/50 17 front and rear, which I've got, or 205/50 17 front and 225/45 17 rear. I'm glad I've got the former, as it allows me to swap tyres front to back to extend life. But, if I had wider rears, I would probably have enough grip. However, does this really matter? In a world where car enthusiasts are bemoaning the ever increasing grip levels manufacturers are adding to cars at the expense of balance, poise and adjustabilty, handling limits, and therefore fun, are becoming more and more out of touch at road legal speeds. These tyres warn me that I'm reaching the limits well before I actually do. They are a triumph of subjective feel over outright grip. Not one for the max power brigade. But if you understand and appreciate the difference between roadholding (how high the limit) and handling (the nature in which it gets there), these might be for you.
My last car was a Clio 182, and I went from Michelin Pilot Sport 3 (very grippy, but tramlining and not enough warning towards limit) to Continental PremiumContact 2 (less grip, but nicer feel). When I bought the tyres for this 130i, I nearly went for the new Michelin Pilot Sport 4, but I chose the Contis instead and saved £50. Next time I might try the Pilot Sport 4. I expect they will grip better, but I have a funny feeling I will prefer the subjective feel of these Contis.
