no worries,
my opinions are based on readin gand not experience with those particular types of tyres. there may well be other sout there with more experience with these tyres. but i must admit, over the 8 car forums i have frequented, i've never seen anyone run all season tyres on a car.
people tend to either run summer tyres all year round, or have a set of winter tyres to swap to when the weather gets bad.
need to find what works best for you.
