Old thread but I have just had a couple of tyres on my car, 225/40x18 Good Year F1 Supersports.
These are getting rave reviews and owners are saying that they're on a par if not better than Michelin PS4
They're brand new and need scrubbing in obviously, but even from a short drive home from the tyre shop, less TCS intervention accelerating in 3rd than before, which is promising. Dull 'looking' tyre though, all of them look the same these days?
