As street tire wear closer and closer to the wear bar, the tread block becomes shorter and wider, therefore providing more grip and consistent traction. Just right before it cords is when a set of street tires are at its best grip. That's why you'll see racers where lap time matters actually SHAVE off most of the treads before they use their tires.

I'd say that's more the exception than the rule. My contis were slippery as hell when I was approaching the wear bars...
