What should be the minimum tread depth for the non-steering wheels of a truck?

[DelMarcus]

The tread depth for the non-steering wheels of a truck should be at least 1.6 millimeters. Below is some relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are made of rubber and will age over time with prolonged use. It is recommended that car owners replace their tires every four years, even if the mileage is low during that period. This is because tires can also age when left unused for extended periods, so it's important to check the production date when purchasing new tires.
