Most winter tire tests cover sizes up to 16 inch wheels, as these are by far the most common winter tire sizes fitted across Europe. Unfortunately, if you're looking to keep your performance car mobile over winter, these tests are largely useless as a reference, as tire patterns and performances can drastically change as the sizes increase.

Luckily Auto Bild Sportscars have us covered with their latest ultra high performance winter tire test. Auto Bild have taken eight UHP winter tires in 225/40 R18 and tested them on a RWD Mercedes C Class across the usual range of snow, wet and dry tests and have included a summer tire as reference.

Snow

During the snow tests the results were close, and the top places varied. The Nokian offered the best snow braking, the Pirelli was the fastest over a lap and the Michelin offered the best traction. All the winter tires vastly out performed the summer tire, which was unable to complete a snow handling lap, and stopped the Mercedes test car in 38.3 meters compared to 22.5 meters for the worst winter tire on test (Horizon) and 20.5 meters for the best on test (Nokian)

Wet

Under wet testing, the summer tire regained some points, winning the wet braking, handling and wet circle tests. The margin was greatest in wet handling, where the summer tire had an average speed of 86.5 kph and the best winter (Dunlop) could only manage 83.2 kph. Under wet braking the margins were closer, with the Continental and Dunlop winter tires stopping just 1.4 meters behind the summer tire from 50 mph and the Dunlop and Pirelli beating the summer tire under the straight line aquaplaning test.

Dry

Again in the dry handling and braking tests, the summer tire showed its strengths. While the best winter tire (Continental) could keep close to the summer tire during dry handling, the dry braking test once again showed where siped tires lose out, with the test winning Dunlop taking 43.5 meters to stop the car from 60 mph, compared to 36.3 meters for the summer tire.
