I run 245's all around on the track, but that is for wear/ future TT class reasons... larger rears will always give more grip... with the smaller rear you will get more oversteer... if they carry a 265 or 275 go with that...
But why general tire? This is going to sound so bad, but you wouldn't go out and buy a high end desktop computer then hook it up to a $100 CRT screen would you?
