At how many kilometers should the wheel hubs of a truck be maintained?

[VonJoanna]

For engineering vehicles, the wheel hubs are generally maintained once a year, or every six months if the mileage is high. Below are detailed introductions about truck wheel hubs: 1. Overview: The wheel hub is the rotating part of the wheel steel inside the tire connected by pillars, which is the metal component mounted on the axle that supports the center of the tire. It is also called the rim, steel ring, wheel, or tire ring. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Classification: The wheel hub is also called the rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes of wheel hubs also vary, mainly divided into painting and electroplating. For ordinary vehicle models, the appearance of the wheel hub is less considered, with good heat dissipation being a basic requirement. The process mostly involves painting treatment, which means spraying first and then baking electrically.
