Not exactly.

Even if the weight is the same, there could be a difference in rotational inertia. The 14" wheel will have the mass of the rim closer to the center of the wheel and will therefore require less effort to accelerate.

The 20's on the truck in my icon hurt acceleration fiercely, but they look cool.
