O.k., o.k. I know we've discussed wheel sizes in the "other" thread quite a bit, but still have questions related to how a wheel diameter impacts performance overall. I also recognize there are some tracks where a 205 tire is faster than a 225 regardless if it's mounted on a 6 or 7 inch rim. For the sake of this argument, let's assume that a person has access to plenty of 6" and 7" rims regardless of the bolt pattern.

I've often heard (from some very intelligent people might I add) that if a car goes down from a 7" rim to a 6" rim, the car would see a decrease in handling performance, again overall. In the "other" thread, it was mentioned that a 7" rim will weigh more than a 6" rim and therefore the 7" rim isn't better. I also stated while only somewhat being a PITA why isn't a 5" rim better than a 6" rim if that were true? Obviously there is an optimum point based upon g-forces, horse power, ect. but I'm unsure where that is.

Here we go again!
