How to check the quality of wheel rims?

Wheel rim quality is not a "dispensable" parameter, but a core factor that directly determines equipment safety, efficiency, and cost. Especially in high-intensity working conditions such as mining, construction machinery, ports, and agriculture, wheel rim quality is even more critical than the tire itself.

Directly related to life and equipment safety , the rim is the "skeleton" of the entire tire system. Once it fails, the consequences are extremely serious . Inferior rims may break, weld, or lock rings may fall off . High-pressure OTR tires may burst or fly off instantly , causing heavy vehicles to lose control and posing a significant risk of casualties . In mines, the cost of a failed rim could be millions of dollars in equipment losses plus irreparable personal injury.

the world's top three OTR wheel manufacturers, HYWG has accumulated over two decades of experience and has always regarded "rim quality" as the lifeline of its brand.

The quality of wheel rims can be checked from four aspects: structural safety, dimensional accuracy, material properties, and surface quality. This is especially critical for wheel rims of OTR, construction machinery, and mining vehicles.

On mining trucks, loaders, graders, port machinery and agricultural machinery operating under heavy loads and complex working conditions, wheel rims are subjected to huge loads , frequent impacts , high temperatures and corrosion and extreme environments for a long time .

HYWG rims are made of high-strength special steel. Starting from high-quality raw materials, the thickness of the plates meets the requirements of vehicles. In particular, the spokes and rim edges are welded fully and evenly, without porosity, slag inclusions, or weld beads , which makes the rims have higher resistance to pressure, impact, and fatigue.

the most basic visual inspection is very important :

1. Check the rim surface for cracks , paying particular attention to the rim edge, weld seam, lock ring groove, and around bolt holes .

2. Are there any obvious deformations ? Are there any dents, bulges, out-of-roundness, or unevenness ?

3. Is there severe rust ?

4. Is the coating intact ? Are there any peeling, flaking, bubbles, or other defects (which affect corrosion resistance) ?

These are all things that need to be stopped.

The dimensions of the wheel rim need to be checked for accuracy : the rim width and diameter , the rim offset (ET) and center hole size , the number of bolt holes and the hole spacing (PCD) , and the rim runout detection data must all fully meet the customer's requirements.
