Diffing out occurs when the inside tyre becomes unweighted during cornering -
and because of the balldiff either being too loose or not thick enough lube in the geardiff (it's that terrible squaling sound some cars make)- because the power isn't so much transferred to the inside tyre, but since the inside tyre is unweighted it's not wearing and instead merely spinning in the air while the outside tyre isn't able to keep up. It touching ground again doesn't really result in wear because the diff's so loose it can't.
Again, tyre wear more often happens from the diff being too tight - being as the outside tyre will try to keep pace with the inside tyre because the car's diff isn't being used as much which results in the outside tyre wearing heavier on each corner as a result of it traveling farther and spinning more.
