The physics are simple actually!

Two objects of the same weight and "shape/size", the rotational inertia will be lower in the one where the weight is most concentrated close to the rotation center.

So, even if you have two wheels of the same total diameter, same weight, acceleration/braking will be better with the wheels that have a smaller rim, as the weight is closer to the rotation axis (or the biggest part of the weight).

The trade off, I would say, is tire deformation on hard cornering, but in light cars like ours I would say that trade off is not as critical as on big heavy porsches/bmws...
