ive been searching but am getting mixed reviews.... so, which setup would be optimal for max performance?

 

you give us no info at all........but the 225 would be good performance depending on the tire

 

it also depends on the offset and ride height. for example, if you had a 17x7 +35 dumped on a 225 your going to mess up your front fenders. Also, i think the tire you choose would be a factor as well. I would rather rock a 215/45 Azenis RT615 over a 225/45 Kumho ASX.
