EDIT: I don't know if these tires still exist, but I had a flashback to my experience over a decade ago and couldn't let my below review stand in good conscience. Once I had travelled around 1,000 miles on these tires and experienced rainfall, they nearly killed me. I rounded a corner at a perfectly normal speed to find my traction control light flashing frantically; I suspected oil/diesel on the road, but as I continued to drive, I found the tires had such terrible lateral grip that I pulled over to check tire pressures (I remember the shock so vividly). It was only a few hundred miles later that I had to bin the tires and replace them with Goodyear Asymmetrics, and I learned never to take a chance on unknown tires (or trust reviews of new, unworn tires) again - at best it costs you in insurance, at worst it costs your life!
Only trust reviews where the reviewer has put over 1,000 miles wear on the tires, THEN driven in wet and cold weather. The BBC did an expose on cheap tires failing miserably after they wore through 0.5-1.0mm of tread, no longer testing anywhere near as well as their official test performance.
Wow, excellent tires! Replaced my Dunlop Sport SP01 run-flats at the back with these and they are amazing. Although I've only travelled around 500 miles on them the winter performance is outstanding. Not even a hint of wheel spin under maximum acceleration, even when it's -2. Accelerating off a roundabout or leaving a junction is also much better than the Dunlops.
The tires to have a tendency to tramline although this can be almost eliminated with a few extra PSI. The extra wide tread pattern disperses water as if it wasn't even there.
Treadwear is an unknown at present, having only travelled 500 miles but even if they only last half as long as the Dunlops they were less than 1/3rd the price!
My advice is to try them at manufacturers recommended pressure and if the sidewalls move slightly on heavy cornering, or you feel the car following ruts in the road, add 2-3psi and try again.
