I allways end up going back to 15"'s general rule of thumb smallest wheels you can get over your brakes. running 280mm brakes that means 15 inch wheels for me. seem to have built up a collection of J7 rims they take a 195 or 205 tyer well.
195/50/15 have allways been the go to tyer size for general tyers as well probaly because they are relativly cheep / avalible
