While this may be true, it is highly unlikely that any reinforced sidewall will weight as much as the "sidewall" made out of alloy on the larger wheel.
More likely the AP2 wheels are the same weight even given the larger diameter, either due to a lighter alloy/different construction (forged vs. cast, etc.).
