Michelin Pilot Sport 4 or Exalto PE2?

[DrRobin]

My rear wheel size is 225/50 R16, Conti do make a tyre in this size, but I can’t find anyone round here who will supply and fit, so have gone for the Sport 4s.

I don’t drive my Boxster to it’s limit or even to the point where it is about to loose grip and I doubt very much that I will experience any issues with different manufacturers, but if I do I will get Sport 4s on the front.

Thanks for your help.
