anyone know the benifits of lightweight wheels? - Toyota Yaris Forums

fu, the weights of the wheels themselves could've told you the same thing without going through all that calculation. 10 lb wheels are 33% lighter than 15lb wheels, thus requiring 33% less energy to move them.

The second half of your equation is only comparing the total weight differences of the car with the two different wheels. The two front wheels are attached to the engine, so you'd also eventually conclude that you have more power to the ground due to less total weight of the moving drivetrain.

Cliffs notes: you're only looking at half the picture.
