then again, there's always other good brands too.
Yokohama, Michelin, Pirelli, ... a long long list to go.
the fact that it's experimenting against that and only that named brand, actually makes me put on my skeptical hat.. sounds like a marketing propagation, no?
that video is comparing a 2nd hand tyres/worn out tyres with a new one, so you can see the result on the tyres affect the braking distance, same goes to other tyres, and i have personally tested, last time when i was running on a NCT5 that is almost touch the safety marks, the braking is so bad, at first i thought is the brake problem, maybe need to refill the fluid or what, but found out it is ok, then after that i changed to the new Falken Ze912, the braking is much better...

i concur hearing this too, to make it quiet, so to say..
also heard that the bigger the "blocks" on the tire tread, the noisier it goes..
as for the no-tread = more grip, was coming from contacting surface perspective.
since the slick tires comes in material and operating theory of its own class, i agree that it's not a fair comparison point.
you can just compare like that, grip isn't just about the more surface of contact the better it is
i dont know which logic is best to explain, i feel hard to explain in here, all this come from my experience, after the chinese new year trip back to my hometown, i finally realize how much a tyres can contribute to a human life...
if you try to think out of the box, you can visualize, semi slick tyres gain grip with the heated/melting rubber, the rubber will become hot and soft so it can stick to the ground, thus improve handling and acceleration.
on the other hand, our car tyres are made of harder compound and it will not melt (unless you go over the tyre rating), so when the thread run out, the tyres will have no grip and will be prone to wheel lock (for car without ABS) because it doesn't stick to the ground like what semi-slick tyres did, the thread on the tyres not just for comfort and water disperse, it also help the tyres to "stick" on the road, the thread on the tyre if actually slip between the small rocks in the road surface (our road surface is not as smooth as silk, it is rough), and when you check your tyres, you will actually see there are some rat bite at the thread there, this is due to the constant friction on the ground.
that's just my opinion, correct me if i'm wrong.
