And seeing as you are fond of quotes, this is from Continental's website:
In the UK, as there is no legal requirement to use winter tyres, the term "summer tyres" doesnt really mean anything other that "a tyre that isnt classified as a winter tyre", everything is a "summer tyre" from a MPSS through to a Chingdu Widowmaker
My friend,........the difference between summer and winter tyres is not the locacation where they are used,.....its the window of temperature they are used. "summer tyres" work well down to 6-7 degrees Celsius ,....winter tyres from 6-7 degrees and below,....so what??????
