Someone is going to have to explain to me why a simple change in tire
diameter could have any effect on an ABS car's ability to function. In the
case where a larger tire were used, the system should "see" it as just
lower speed (reduced wheel RPM). The opposite would be true of a smaller
tire diameter.
That does, of course, assume that the relationship between front and rear
tire sizes remains constant. If a car came with 195/60's and someone put
205/55's all around, why would that cause a problem? Now if someone does
as I did on my Colt and put 225/50's on the front, and 185/60's on the rear,
that might send an ABS computer into a meltdown mode.... (no, the old tech
'89 Mitsubishi Made car does not have that sophistication... or a suspension
worth a hoot either...)
