Braking制动测试 The braking distance was measured on ice, snow, wet and dry. The tests were performed in different temperatures and the final result is an average of validated test runs. The results are shown as distances for ice 50-0 km/h, snow and wet80-0km/h and dry 90-0 km/h. Braking tests on snow and ice were done both outdoors and in an indoor facility, where it is possible to avoid problems caused by changing weather. 制动距离是在冰面、雪地、湿地和干地条件下测量的。测量是在不同温度下进行的，最终结果取自所有有效测试结果的平均值。测试结果是取自测试轮胎在冰面速度由50km/h降至0km/h的制动距离，雪地和湿地测量的是速度由80km/h降至0km/h的制动距离，而干地是由90km/h降至0km/h的制动距离。冰面和雪地的制动测试同时在室内和室外进行，这样可以有效避免天气变化对测试结果的影响。 Acceleration加速 Traction on ice and snow were by accelerating the car between a certain speed range. On ice the range was 5-20 and on snow 5-35 km/h. Like braking, also the acceleration tests on snow and ice were done both outdoors and indoors. 在冰面和雪地条件下的牵引力是在一个特定的速度范围内给车加速。在冰面上是由5km/h加速至20km/h，在雪地上是由5km/h加速至35km/h。同制动测试一样，冰面和雪地上的加速测试也是同时在室内和室外进行。 Handling操控性 Dynamic handling grip was tested objectively by recording lap times on ice, snow and wet asphalt. The test was done by different test drivers and the final result is an average of several test runs. 动态操控抓地力是通过记录在冰面、雪地和湿柏油路上的单圈时间来客观测量的。测试由不同的测试驾驶员完成，最后的结果取自多次测量结果的平均值。 Handling behaviour操控性（主观） In addition to lap times, the driver gave subjective comments of the tyre, its behaviour and most importantly, how safe a tyre is for a normal driver in every day traffic. The subjective test was done on ice, snow, wet and dry. 除测量单圈时间外，驾驶员还对轮胎做出主观评价-轮胎的运行表现，尤其是日常行驶中的安全性能。这项主观测试在冰面、雪地、湿地和干地上进行。 Stability稳定性 Driving stability was done by driving typical winter roads which were grooved by either traffic or by road maintenance. The tyres were evaluated by the feeling inside car and also by how much steering corrections had to be done in order to maintain driving direction on grooved roads.The stability evaluation is included in the handling grades. 驾驶的稳定性是在因车辆行驶或是维护造成的布满沟壑的典型的冬季道路上测量的。结果是通过车内驾驶员的感受以及在布满沟壑的道路上为了维持正确的行驶方向而做出的转向程度来评估的。稳定性的评估体现在操控性结果中。 Noise噪音 Tyre noise was evaluated subjectively both by measurements and subjectively inside car. 轮胎噪音是根据测量值和车内人员的主观感受来主观评估的。 Rolling resistance滚动阻力 Rolling resistance was tested as on outdoor coast down method. In this test, the car was let roll freely from 80 to 40 km/h, measuring the rolling distance. The test was done in non-windy conditions on a flat surface and repeated in a different temperature. 滚动阻力是通过在室外滑行来测量的。在这个测试中测量的是车速由80km/h降至40km/h的过程中车轮自由滚动的距离。此测试是在无风情况下的平地上进行的，并且在不同的温度下进行重复测试。
