Brilliant now they have around 400 miles on them. Very grippy both wet and dry (even at these current >10°C temperatures we have at the moment), and much, much quieter than the Bridgestone's.
It's like I said before, the Bridgestone's weren't total crap, they just struggled to cope with the power and torque that the performance Golf's have on tap, and were a little too quick to spin up when it either got damp or the temperatures dropped, but they did give fantastic mileage. I changed them with still just under 4mm all round, and at 20,500 miles, so I doubt the Goodyear's will last that long, but they do totally change the driving pleasure of the car.
Only last night I needed to get a quick getaway at a roundabout, and it was circa 5°C and quite wet. If I'd have booted it with the Bridgestone's on, the traction control light would have been on for several seconds, and I would have to cut the power or feather the throttle to get away, even then with wheel spin. Last night however on the Goodyear's I saw a gap and went for it, and aside for a momentary blip of the traction control light (not full throttle by any means) , the car just catapulted away from the line with no drama at all..
Very pleased.
