Its not a tracking issue. Its the caster angle, so will affect every car where the owner accelerates out of, or round corners.

Basically caster is negative camber placed onto the wheel when turning, the car leans onto the outside tire on a bend which now has say 1.5deg of negative camber but the inside wheel also has this increased caster but the car is leaning on the outside tyre so the inner tyre only has the inner edge in contact with the road, if you now accelerate then you will wear out the inner edge of the inside tyre.
