In the automotive field, the wheel hub, as the core component connecting the tire and the vehicle, directly affects the vehicle's handling, safety, and passability. For off-road enthusiasts, original wheels, modified wheels, and off-road wheels each have their own characteristics. Through multidimensional comparative analysis, the differences between the three can be more clearly grasped, providing professional references for practical selection.
1、 Comparison of Manufacturing Processes

Process limitations
|
|
Original wheel hub
|
Low pressure casting
|
Injecting liquid aluminum alloy into molds under low pressure environment for molding
|
Cost controllable, suitable for large-scale production; Mature craftsmanship and high yield rate
|
Metal density is relatively low, and it is prone to fatigue under high-strength working conditions
|
|
Modified wheel hub
|
Spinning casting, forging
|
Spinning casting: Spinning wheel rims on the basis of casting to strengthen the structure Forging: High temperature and high pressure forging of aluminum alloy billets
|
Spinning casting balances cost and performance; Excellent strength and lightweight performance of forged wheel hubs
|
The forging process is costly; Spinning casting still has lower strength than forging
|
|
Off road wheel hub
|
Forging, special steel processing
|
Aluminum alloy forging or manganese steel, chromium molybdenum alloy steel processing
|
Customizable high-strength structure; Adapt to extreme environmental demands
|
Special steel wheels have a relatively large weight; Customization leads to increased costs
|
The low-pressure casting process for original wheel hubs focuses on balancing mass production efficiency and cost, while the spinning and forging processes for modified wheel hubs emphasize performance improvement. Off road wheel hubs are selected based on their adaptability to extreme working conditions.
2、 Performance parameter comparison
1. Size and bearing capacity
The size design of the original wheel hub is based on the standard configuration of the vehicle, and its load-bearing capacity meets the requirements of regular use; The modified wheel hub is more flexible in size, and some products can improve their load-bearing capacity by optimizing their structure; Off road wheels are designed with thickened rims and reinforced ribs to significantly enhance their load-bearing capacity and deformation resistance, in order to cope with heavy-duty off-road scenarios.
2. Install adaptation parameters

PCD and hole position adaptation
|
Deviation (ET value) characteristics
|
Center hole matching
|
|
Original wheel hub
|
Perfectly match the original factory parameters of the vehicle
|
Ensure that the vehicle's steering and suspension systems are under normal stress
|
Accurately fitting the vehicle axle head
|
|
Modified wheel hub
|
Strictly follow the original factory parameters for selection or customization
|
Large adjustable range, used to change wheelbase and appearance
|
Need to ensure the accuracy of fitting with the shaft head
|
|
Off road wheel hub
|
Compatible with various off-road vehicles, some support customization
|
Use negative offset to widen the wheelbase
|
Adapt to off-road tires and modification needs
|
Modified wheels and off-road wheels have more flexibility in parameter adjustment, but require professional calculation and debugging to avoid affecting vehicle performance and safety.
3、 Comparison of Material Selection
The original wheels are mostly made of 6061 aluminum alloy, which balances cost and basic performance; In the modification of wheel hubs, high-end products often use 7075 aluminum alloy or carbon fiber composite materials, pursuing lightweight and high strength; Off road wheels are made of special steels such as manganese steel and chromium molybdenum alloy steel, in addition to aluminum alloy, to enhance their impact resistance and wear resistance.
4、 Comparison of adaptation scenarios
Original wheels are suitable for daily scenarios such as urban commuting and light off-road driving; The modified wheel hub can be adapted to track driving, road performance improvement, or medium intensity off-road according to user needs; Off road wheels are designed specifically for extreme off-road environments such as rock climbing, desert crossing, and heavily muddy roads, ensuring the vehicle's passability and reliability in complex terrains.
5、 Comparison of Safety and Regulations
Original wheel hubs strictly follow the quality standards of automobile manufacturers and national regulations, and have passed multiple safety tests; The modified wheels of legitimate brands need to pass ISO/TS 16949 certification, but there are inferior products in the market; Off road wheels also need to meet safety standards, and during modification, they must ensure compliance with local traffic regulations to avoid safety hazards or failure to pass annual inspections due to significant parameter changes.
By comparing the manufacturing process, performance parameters, materials, adaptation scenarios, and safety of original, modified, and off-road wheels, it can be seen that each of the three types of wheels has its own emphasis. Original wheels provide stable and reliable basic performance, modified wheels meet personalized and performance improvement needs, and off-road wheels focus on extreme off-road conditions. When choosing, users should comprehensively consider their own driving scenarios, budget, regulatory requirements, and professional advice in order to select suitable wheel hub products, ensuring driving safety and driving experience.
