ABS kicks in while driving

[cps68500]

My right side ABS has kicked in a couple times recently while driving @~30mph.  I wasn't even braking at the times it happened.  The ABS stays on for 2-3 seconds and then shuts off.  I live in New England, I definitely know what it sounds and feels like.  The last couple times it happened however, after the ABS noise / vibration, the truck pulls to the right for a quick jerk, then everything back to normal.   

I bring it to the dealer and got the call today they found the problem...  The rear tires have less tread than the fronts.  That's their answer. Replace the tires.

Before I go ape sheet on them when I pick it up tomorrow...

Is there any truth to this at all or could it be plausible?

A properly designed stability control system should be tolerant of very slight differences in tire diameter and should not activate due to that.

There is a TSB on that issue. I was having the same problem and this fixed it. I had to tell the dealer about it.
