Please ignore phrases like: great tire for the money. This is a great tire. Period.
I went from Dunlop SP Sport Signature non-run-flates and then Michelin PIlot Sport A/S to these Kumhos, and he Kumhos are easily as good or even better than both of those much more expensive tires, all on my slightly modded MINI Clubman S. Haven't had a chance to push them when it's wet yet.
A TireRack salesmen recommended these, even after I told him that price was not an issue. They handle great, have low noise and a good ride for a performance tire, though I can see that tread life will be lower than advertised. The only reason these are cheaper is probably because they are made in Korea...the 4Xs definitely outperform the Dunlops on most levels, and are as good as the Michelins (even better as far as road noise). There is very little tramlining, and I feel confident pushing them.
It's strange to see some people complaining that they feel floppy -- this must be very car and suspension dependent, because on my Clubman S (with Koni FSD shocks and a stiffer rear sway bar) they feel as or more strong than the Dunlops or Michelins that I had, when it comes to sidewall stiffness.
