From what I understand about it which is probably misunder stood especially by me is that the tire size should match the weight balance of the car. For example if the weight is 40/60 front to rear, the tires should be narrower on the front to achieve a balanced tire loading on all four corners. If all four tires have the same loading or lbs of weight per square inch of footprint you should have neutral handling. While looking for tires and wheels on ebay I noticed that the tire sizes on the porsch rims were always different from the front to rear. They run something like this 205/55 on the front and 215/50 on the rear. The tires should be about the same diameter. I think this is because of the aspect ratio. As the tire gets wider to retain the ratio the sidewall has to be taller.
Once you get this all sorted out then you have to worry about sway bars, springs, shocks, etc. All these items have similar effects on the handling.
