It's more complicated with different tire sizes. For explaination consider that front and rear tires are same diameter.
If you have more rear drive, then there will be more turns of the rear tires than the front over a given set distance. For example, 10 turns of the rear tires for every 9 turns of the front. But both front and rear have to arrive at the end point at the same time. Therefore the rear are (over) driving the front tires. At the extremes you could have a 1:1 drive ratio or 2 wheel drive to the rear wheels.
The effect of rear over drive is over steer. With the "proper" amount the back end checks out a few degrees and the power not only drives you foreward but also to the inside of the turn i.e. faster cornering.
