No they didn't.

In a strictly technical / laboratory sense, maybe not. But in practice, they stopped just the same. I also slow down to a stop (regen braking is amazing) and don't slam on my brakes at a stop light (like some drivers I routinely scowl at). And driving through the country and having to slam on the brakes when a deer jumps out (which was common where I lived), I noticed no appreciable difference in stopping distance between the two tire types.

...huh? ABS has nothing to do with rolling resistance...

ABS prevents the tires from locking up and skidding (anti-lock braking system, hence the name). Under normal driving conditions, it merely helps you maintain control, but on slick roads, locking up the wheels can skid you further than without it. So, no, ABS doesn't directly relate to rolling resistance, but it's part of a system along with the tires that contribute to stopping distance....which is what I was talking about.
