diameter and weight distribution
quote: "The spec the tire manufacturor gives for the heigth of the tire used; is the factor to consider when speculating your theory"
That's right. I've seen a few post where people talk about sizes and weights, and i thought i'd chime in with another perspective. Of course the amount of weight needs to be minimumized. We all know more force is needed to accelerate a larger amount of mass. However when it comes to wheels, there is more involved than just lowering the amount of weight you want to get to 60mph or 1/4 mile.
Think of a bike tire. Almost all of it's weight is on its outer circumference. For it's weight, it requites a large amount of torque to get it rotating. An ideal wheel would have the max amount of it's weight near it's center of rotation therefore minumizing the effects of rotational inertia.
Also interesting to consider is that this applies to stopping the car aswell.
Two sets of rims, same weight. The larger (bigger diameter) will require more breaking power to stop.
