The ones from Germany are the ones to have. However all the other ones are not fakes, they are just made using cheaper rubber, which means that they are not as good. Although you should notice if they are the different ones as they have a slightly different tread pattern. They have also stopped making Eagle F1s now finished on Monday. They are now making the Eagle F1 Asimetric, which is still a very good tyre but dosent have the same 'aggressive' tread pattern. Should still be able to get them for the next year or so though as they made so many.
