    My original “eco” tires stopped the same as the standard ones.

    No they didn’t.

    They’re “eco” because they have less rolling resistance and are slightly lighter.

    They have less rolling resistance because they’re made of a harder compound, with reduced grip.

    Plus, with ABS, you’re not likely to lock the wheels up such that the decreased resistance would be significant.

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

      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.

        In every sense they do not.

        I also…don’t slam on my brakes at a stop light

        How you drive under normal conditions has absolutely nothing to do with the capability of the tires in an emergency situation, which occurs regardless of how good or careful you are.

        I noticed no appreciable difference in stopping distance

        You won’t if you don’t get out and measure it. But I guarantee it is there regardless. The difference, regardless of how noticeable, can easily mean the difference between life and death, or even crashing at all.
