Ok, I got into a discussion with one of my co-workers about rotational inertia. One of us is wrong I am trying to find out which one. Here is my view on it. Tire height and width being the same, and wheel weight being the same, I think that a car with a 15" rim will be faster then a car with a 17" rims. The reason I said that the smaller rim would be faster is because the weight of the rim would be closer to the center allowing the engine to turn it faster and thereby accelerate faster. He says that the weight distribution wouldn't matter and that the only thing that would hinder acceleration would be tire width, since a wider tire would provide more traction and it would require more power turn wider tire. What do you guys think. I need some scientific data on this, but I am having no luck finding any. Maybe we're both off base, but hopefully it's not me hehe. Thanks in advance.
