Came fitted from the factory on my new Golf. Three days of ownershiop and i almost got stranded in 2 inches of snow. Absolutely hopeless even with full tread depth. Further snow fall meant the car stayed on the drive, in favour of our Fiat Panda third car which coped without issue in 6" of snow even though that doesn't have winter or all season tires.
Wet weather grip was OK when new, but once 50% worn the car had a tendency to feel nervous on white lines even at constatnt speed. Wet cornering mediocre, little confidence and feedback from the tire - i'd have expected better from Bridgestone. Dry performance was good, with no great weaknesses, but nothing special either.
Noise levels were acceptable (Dunlops are much worse apparently on the latest Golf). Comfort levels were fine - reasonable touring tire with a bit of sportiness but i wouldn't fit it to any hot hatch or sports car. This isn't a long life tire - the front tires are at the wear limiters after 14000 miles; not good for a 105bhp car which is driven 60% of its time on dual carriageways. The rear tires will probably last to 22-24k miles, not bad but nothing special. I'll fit the same again to the front axle, but once the rears are worn out i'll be looking elsewhere for the next set.
This winter i'm also fitting winter wheels - the use of summer performance tires in cold, rural climates just doesn't work, even in the UK.
