The company I work for was the original UK importers for Federal Tyres.
My knowledge is limited to "normal" road tyres and not "trackday" tyres, but my
experiences weren't good ones. Several of our distributers refused to take this
brand from us, following instances where they had fitted new tyres to a car and
the driver had frightening experiences in the wet including a couple of minor
accidents. We found Federal to be unhelpfull in resolving these issues and poor
trading partners. To cut a long story short, stopped dealing with them.
Their new generation of tyres may be very much better, but I would need to be
convinced of that before I fitted any of their product to any of my families vehicles.
