Well guys, ideally for cornering, sidewall flex regardless of profile you want to maintain a high rim width to tire ratio (.85 or better no definite rules) used in racing and street. e.g. stock 225 is 8.858". a 7.5" wheel/8.858=0.84 in other words 84%, not bad. A 255 on stock wheels gives a ratio of only 74% kind of like running in a shoe that is too big with your foot flopping around. Imagine a 225 on an 8" wheel, 90.3%, outstanding, quick crisp reflexes. The new Mustang has a ratio of 86% and Acura TSX 82% for comparison.
