I was shocked too, but he said he had tried most of the other big brands and then someone at the local Merc garage recommended them, he also said one of his mates with a 911 also uses them
He also said having had used both Pirellis and Michelins, the Falkens hold the road just as well and also last a bit longer.
I'm usually a bit of a brand snob, but can't see why its worth paying £50+ a tyre more if these are as good
