Put these on two vehicles. One FWD one AWD, both cars reacted well, they seem to make small clouds behind the car when it is wet. But they do increae fuel consumption.Guess you still can't have good cold weather grip with tyres that are good on fuel?
Wear wise they are no better orworse than other tyres, they do "hum" on smooth tarmc, but it's not instrusive. They seem to be very good at communicating as well, give you plenty of warning before sliding, not in the form of noise, but in feel.
I guess they are an old design now? Not as good as Vector 4 seasons but adequate for most uses.
