ok true, i had enough time. And by the way, every time i look at your sig, i think thats my car. Needless to say, your car is very hot!
ok, chew on this- equal masses at equal radii have equal moments of inertia (rotational inertia). unless the wheel spins seperately from the tire, the radii is to the tire edge not wheel edge. Granted, the dispersion of the mass has somehting to do with it also. If the wheel is heaverier near the hub, and lighter at the outside, it will spin faster then if the weight of the wheel was towards the rim. so there are many minute details to consider. Look at it like this- There is 1 rod mounted vertically in the ground, another rod is attached to the top of the statiionary rod at dierclty in the center with a pin that allows the upper rod to spin freely in circles. the entire circumfrence of the upper rods circular motion remains constant, now add 2 equal weights to the outside of each end of the spinning rod and take note how fast it spins appllying a mesureed torque. Now, move those weights towards the center of the upper rod splitting the distance between the ends of the rod and the center pinion. apply the same torque, the wheel will spin faster, so its not just a mtter of how big the wheel is but how the wieght is distributed. buty i see what ur sayin. LOL
Personally, if your not on the drag strip, go with the big dubs they look better!
