Category: Wheels Tires

Except for extra heavy-duty vehicle wheels, aluminum wheels covered all sizes as steel wheels.

Fuel Oil Economic:

As aluminum is lighter weight than steel, such as 22.5×8.25, aluminum wheels save 2L oil than steel wheels in 100km distance, aluminum wheels also decrease 26% tire wear compared to steel wheels.

Weight:

Aluminum is half of the weight of steel wheels of the same size.

Material:

Aluminum is T6061, steel is Q grade steel plate

Manufacture Method:

Aluminum has casting, forging & extrusion shapes.  To compare steel welding.

Roundness:

Aluminum wheels use CNC machining, and steel wheels rolling plate.

Dynamic:

Aluminum wheels have uniform density, steel wheels worse on roundness and welding.

Cooling:

Aluminum material has better cooling performance than steel.

Impact:

Aluminum belongs to alloy material that tensile performance better than steel.

Pressure Test:

Aluminum deforms 50mm under 73,000kgs, steel deforms 50mm under 13,600kgs.

Outward:

Aluminum has better gloss than steel.

Regarding extra heavy-duty vehicles, will still use OTR steel wheels, such as 5pcs wheels, and 7pcs wheels, which are easy to group tother and lower cost.
