It seems that 255/35/19 front and 275/35/19 rear would cause less understeer than 245/35/19 front and 275 or 285 rear. There would be only .79 diference in width like my stock G35-6MT. If seens that more stagger on width would make the car handle worse. Has anyone tried this combination. If so what did you think? I want to improve handling, not just improve looks.

 

many guys are running the SAME diameter front and rear on their G's . Since there will be some stagger with a 255/35 and 275/35's, I don't think you'll have any problem. I plan on going to 255's upr front when my current tires wear out.
