Is my brother's Porsche Boxter fitted with the correct tyres?

My brother has just purchased a 2001 Porsche Boxster 3.2 S which appears to be in excellent condition, but I am concerned that the tyres fitted may not be compatible front/rear. Fronts are Pirelli P Zero Rosso 205/50ZR17 N3; rears Pirelli 240 Snowsport 255/40/R17 98V N1. Your comments welcome,

The tyre sizes for the car are different front to back, but it appears that this car is fitted with winter tyres at the rear only. That was never a good idea, even in winter. You need to fit new Pirelli P Zero Rosso 255/40/R17s to the rear.
