My point is that it collectively may not be a massive difference, but it is a perceptible one.
Also, pragmatically speaking, working with mounted tires is hard work and my back appreciates lifting lighter things.  |
Of course, the weight reduction is about 1% going to the lightest wheels, so giving you about 1% change in power to weight ratio, several times the effect of the wheel rotational inertia change on acceleration. As I previously mentioned, bump absorption change will be the biggest thing that will be noticed.
