The combination of wheel hub motor with curved tire and flat tire has their own advantages and disadvantages, and the specific selection needs to be comprehensively considered based on the robot's purpose, performance requirements, and usage environment. The following is a detailed comparative analysis of the two:

Curved Tires

Advantages of curved tire

1.High comfort
Curved tire have thick tire walls and strong cushioning ability, which can effectively absorb road bumps and improve stability, especially suitable for uneven roads.
Due to the direct drive of the wheel hub motor, the thick tire wall of the curved tire can reduce the transmission of motor vibration to the vehicle body and improve NVH (noise, vibration, and acoustic roughness performance).

2. Strong adaptability
Low requirements for road quality, suitable for poor road conditions such as potholes and gravel roads, and less likely to cause wheel hub deformation or tire bulges due to impact. At the same time, curved tires can provide better traction and stability in complex road conditions.

3. Hub protection
The curved tire has a higher sidewall, which can reduce the risk of the wheel hub directly hitting the curb or obstacles, and lower the probability of mechanical damage to the wheel hub motor.

Disadvantages of curved tire:

1. Poor maneuverability
The tire wall is relatively soft, and insufficient lateral support during high-speed cornering can easily cause the vehicle to roll, affecting the accuracy of handling.
The torque response of wheel hub motor is fast, but the deformation of curved tires is large, which may affect the efficiency of power transmission.

2. Weak braking performance
Due to significant tire deformation, the contact area of the tire surface changes significantly during braking, and the braking distance may be longer than that of flat tire.

Flat tires

Advantages of flat tire:

1. Excellent maneuverability

Short tire walls and high hardness provide stronger lateral support, making the car more stable when cornering at high speeds

2. Stronger braking performance
Flat tire has a larger contact area and less deformation, providing more direct grip during braking and shortening braking distance.

Disadvantages of flat tire:

1. Poor comfort
Thin tire walls, weak cushioning ability, and direct transmission of road vibrations to the vehicle body.

2. Easy to damage
High requirements for road quality, prone to bumps or bumps when encountering potholes or road shoulders, resulting in higher maintenance costs.

3. Impact on battery life
Flat tire usually have high rolling resistance, which may slightly increase power consumption and affect the range of wheel hub electric vehicles.

Shenzhen Zhongling Technology Co., Ltd, is currently a leader in the domestic hub motor industry. Its hub motors already have many types of tires to choose from. We will uphold our original intention, never forget, and strive to provide better products for everyone.
