휠·타이어

Wheels and tires carry a commercial vehicle weight, transmit driving and braking force to the road, and let the wheels turn freely. This category groups the wheel-end parts that make that possible, such as the wheel hub that the wheel mounts to and the wheel bearings that let it rotate smoothly. These are safety-critical, load-bearing parts.

The wheel hub provides the mounting face the wheel bolts to and carries the load between the wheel and the axle. Inside it, the wheel bearings let the hub and wheel turn with very little friction while supporting the vehicle weight and the loads of braking and cornering. Together they keep the wheel rotating smoothly and located correctly.

Wheel-end parts wear with mileage, and contamination through a failed seal or impact damage speeds it up. Common signs include a humming, grinding, or growling noise that changes with speed or in turns, vibration, wheel play or wobble, uneven tire wear, and pulling. Because a badly worn wheel bearing or hub can in extreme cases let a wheel separate, symptoms should be inspected promptly by a qualified technician.

The right wheel-end part depends on the vehicle model, the axle, and the part dimensions and load rating. Use the categories below to find the specific component, and confirm each part against the vehicle specification before fitting.
