Tell me something I don't know, like, why this tire's tread is crowned so much.

Tires tread width too wide for the wheel will ballon the center of the tread.
When I was on the road and one of my truck or trailer tires were more rounded more than the other same tire I used my tire thumper on the treads centers. A tread delam has a completely different sound.
