These tyres, 215/40 R17, came with the car, a Polo BlueGT and whilst they're good in the dry, are pretty much a let down in every other regard, excepting possibly wear. After around 28,000 miles, there's about 3-4mm left. Putting the power on in a corner, it is quite easy to lift a back wheel off the ground, but without power to pull the car through, the under steer is terrible. I am not confident with these tyres in the wet and once the temperature falls below 5 or so degrees, there is no grip at all except on a totally dry surface (hence the winter tyres). The Polo chassis probably doesn't help, but I have driven other Polo 6R's (loan cars) that felt more sure footed.
These tyres give the car a very firm and jittery ride, don't react well to surface imperfections and so noisy, even winter tyres (Goodyear Ultra 9) are noticeably quieter.
So, I've had enough of them and will be replacing the 17 inch wheels with 16 inch in order to change to slightly narrower but thicker and (thankfully) quieter tyres.
