I heard over the weekend that there was a problem with the ABS system if you run all four tires the same size. Anyone have any info on this? I obviously have the same size all the way around.

 

I don't have the answer but I do remember reading some threads which talk about this. As I recall there was concern that the ABS measured wheel revolution and based its response on the the different circumference front to back. Some thought that changing the ratio between front and back wheels might confuse the computer and render ABS less effective.

I couldn't easily find the thread but this is what I recall.
