Most usual - running with the wrong pressure. 2nd most usual - poor wheel alignment. More rare - poor shocks, draggy brakes. Long shot - teenage son who borrows the car.
Yes, because the tire gets hot and this causes the tread to wear faster.
Completer wear of tread surface -(creating an unsafe tire ! )
It is an indicator of tire tread wear.
If you mean tire tread depth, the minimum is 1.6mm.
Friction between the tire and the road surface generates heat and causes wear on the tire tread. As tires grip the road during acceleration, braking, and turning, the rubber compounds in the tread gradually wear away. The constant contact and movement lead to the loss of material over time, resulting in reduced tread depth and performance. This wear can be exacerbated by factors such as driving habits, road conditions, and tire maintenance.
Tire spec in PA is 2/32 of an inch of minimum tread
Minimum LEGAL tire tread depth is 2/32nds of an inch.
1 mm on whole tire. If any part of tread is less then it should be replaced.
The tread is what grips the road.
Pressure is equal throughout the tire.

A tire cupping can be caused by tread being lost. A tire cupping means that it should be replaced as soon as possible. You do not want a cupping tire to be used while you are driving. Air can escape and cause a flat.
