> the air inside a wide tire doesn’t add weight This is true, but it's not weight that matters for acceleration, it's the mass, which that paragraph gets confused about. The air inside does definitely have a little mass. The difference in mass between wider and narrower tires does have some effect on handling, even if not on acceleration.
