This is a terrible analogy. These tires are selected based on the ability to hold a certain number of G forces when the tire is at 300 degrees and if the track is oval, banked, road course or street course, and if wet or dry, concrete or asphalt, etc, etc, etc. These tires have zero to do with the thread. But if you notice, the pro's use skinnier tires in front. That is because a wider tire is much harder to turn in the corners under deceleration and may grip too much and throw the rear out of tow or the driver not able to turn the wheel.
