Anyone bought any tyres(car or bike) from THESE GUYS (http://www.blackcircles.com/)before?
They seem to be a bit cheaper than any of the other main tyre dealers although they sell them via them anyway?

I bought some supercorsa's from them last year. good price & free delivery iirc. got them fitted for £10 at a trackday
