I was looking at tyres earlier this year, due to a pin prick on edge of front tyre, that a few years ago would be repairable with a patch, but now the tyre shops won't patch it.
so wanting to keep all 4 tyres the same, and the Toyo Proxes no longer available in the se sizes, I did some measurements and looked at other options. I cam up with the idea of a slightly wider rear tyre, and found these are available:
2 x Yokohama A008P (Porsche) 225/50 R16 W (92), Asymmetrical
2 x Yokohama A008P (Porsche (N0)) 245/45 R16 W (94), Asymmetrical
So I go them, and had them fitted to my spare set of alloys after getting those refurbed. Not gone far on them yet, but no problems, fit nicely, and look good, they have a more traditional tread pattern.
