Why is the tread depth for new tires set at 10/32″? Why can’t it be 20/32″ for example to last much longer? eli5

If the tread blocks are taller, they tend to flex sideways known as squirm and won’t corner or brake as well as shorter the tread blocks. Competition tires usually have less tread depth.
Tire rubber has a finite life. It’s been recommended to replace tires at five years regardless of the amount of tread life remaining. Adding more tread means a lot of people will be driving on old tires with dry rot cracks and not realize it.
