It's still true for normal cars that more tire sidewall is less mass, but I agree that it's probably no longer the case at this level. There are a few wheel makers offering expensive CF wheels for those willing to pay so I can imagine that it will only be a matter of time before you see something similar in F1 - as soon as they prove to be reliable.
