官網上的FAQs有一些說明, They are more effective than winter tyres (and a lot cheaper) and are also more effective than snow chains in certain situations, especially on ice. 這話的意思是說在某些情況下比冬季胎或者雪鍊更厲害,尤其是在冰上. XD The TÜV test included 50 kilometres at 50 kph on dry tarmac. AutoSock passed this "Misuse test", but of course tarmac driving is not recommended as it increases fabric wear very considerably. 德國萊因以時速50公里在乾柏油路上行駛50公里測試通過.(真饒舌) 不過還是不建議這樣使用. In any event the tests show that snow chains are superior in hill starts. 雪鍊在上坡起步方面特強. (隨便亂翻,見笑)
