Another (odd) tyre question - Pse Advise

[andy97]

OK, I know that there are loads of tyre questions on here but I have recently bought a 944 T and it is fitted with virtually brand new tyres (or at least unworn when I bought the car) but they are a very odd combination. Fronts are Avon ZZ3 - 225 50ZR 16 92W and the Rears are Kumho Ecsta Super - 245 45 ZR 16 94W.

What do we all think? Any one get any experience of these tyres at all? If not the odd combination. I think that I know the answer but I am very loath to spend a fortune on new tyres (even at Costco prices), particularly as I may not be able to keep the car too long. I have done a couple of track days on them & intend to do a few more.

Thanks.
