A nice looking tire, which I know is important to some people...., though really not that relevant! When I bought my car it had these tires fitted, so I just replaced like for like. They gripped well in the summer, but lost all adhesive properties through last winter! When the temperature dropped as low as it did, the rubber appeared to go pretty hard, which led to a lot of slip, even when on dry surfaces. This was especially noticeable when parking, when, the first time I realised I had a problem, I thought I had a worn track control rod allowing the wheels to jump! It was a really strange sensation. As it was, and after inspecting all joints, it was purely as a result of the extreme cold affecting the tire. I realise that summer tires aren't even 50% effective in the winter, and hence why most of Europe switch to a winter tire to maintain performance and grip. Of course 'N' rated winter tires are hideously expensive, though can be purchased for £200 each rear tire, and £160 each front tire. Non 'N' rated can be obtained cheaper, but the practice of using non 'N' rated tires, always causes extensive debate. The Bridgestones have only lasted me 8000 miles on the rear, were very poor in the winter, though are cheaper than Continental, and Michelin alternatives. If you are going to be using the car all year round, I would recommend switching to winter tires in the winter once temperatures fall below 7 deg, until they rise again. A swap to a spare set of 16" wheels would reduce the cost of the winter rubber, or budget for the cost of swapping the rubber twice a year on your existing wheels for £10 - £15 a wheel (valve and balance). I have just fitted a pair of Continental Sport Contact 2 Tires (N2), as I can't afford unfortunately at this time to put on winter rubber. I will review these tires in due course, especially with how they fare over the winter. On a side note....., summer tires also wear much quicker in the winter than in the summer!
