Using spheres instead of wheels for most vehicles is impractical due to reduced friction, manufacturing complexity, cost, stability issues, and the historical efficiency and reliability of wheels in transportation.
This is the short answer that I find from my research, Let’s see what are the other reasons behind not using spheres instead of wheels. With pros and cons.

An Overview Of Spheres And Wheels
Before going too deep into the discussion, let’s see what are the main aspects of differences between these two.
| Aspect | Spheres | Wheels |
| Contact Area | Smaller, limited friction | Larger, efficient friction |
| Manufacturing | Complex and costly | Established and efficient |
| Stability | Less stable, harder to control | Stable, self-correcting |
| Control | Limited control, instability | Predictable and controllable |
| Historical Use | Limited use in specific applications | Widespread and well-established |
| Weight Efficiency | Heavier due to more material | Lightweight and efficient |
| Cost | More expensive to produce | Cost-effective |
| Friction | Reduced traction | Effective traction |
| Practicality | Impractical for most vehicles | Standard for vehicles |
Pros And Cons Of Using Spheres Instead Of Wheels
Here are the pros and cons of using spheres instead of wheels.
Pros Of Using Spheres Instead Of Wheels
Omni-Directional Movement
Spheres allow for omnidirectional movement, making them suitable for maneuvering in tight spaces and changing directions quickly.
Simplicity of Design
Spherical structures can be simpler in design compared to complex wheel systems, reducing maintenance and potential points of failure.
Unique Aesthetics
Spheres can offer a unique and futuristic aesthetic, which might be appealing for certain applications or design preferences.
Cons of Using Spheres Instead Of Wheels
Limited Friction
Spheres have a smaller contact area with the ground, leading to reduced traction and stability, which can be problematic for most vehicles.
Complex Control
Achieving precise control with spheres can be challenging, potentially leading to instability and difficulties in maintaining a straight path.
Manufacturing Difficulty
Creating perfect spheres and mounting them in a way that ensures durability can be more complex and costly compared to traditional wheels.
Historical Efficiency
Wheels have been optimized over centuries for various applications, making them highly efficient and reliable for transportation.
Safety Concerns
Reduced stability and control with spheres may pose safety risks, especially at higher speeds or in adverse road conditions.
Energy Efficiency
Spheres may have higher energy consumption due to reduced contact with the ground, making them less efficient for certain applications.
Is It Realistic To Think Of Using Spheres Instead Of Wheels?
No, it is not realistic. Using spheres instead of wheels is a concept that has been explored in certain niche applications and research projects, but it is not realistic for most conventional vehicles and transportation systems. Here’s why:
Limited Traction and Stability
Spheres have a smaller contact area with the ground compared to wheels, leading to reduced traction and stability. This limitation can be a significant safety concern, especially at higher speeds or in adverse road conditions.
Control Challenges
Achieving precise control with spheres can be challenging, making it difficult to maintain a straight path and respond effectively to driver input. This lack of control can result in instability and handling issues.
Manufacturing Complexity
Creating perfectly spherical structures and mounting them in a way that ensures durability and safety can be complex and costly. Wheel technology is well-established and efficient in terms of production.
Energy Efficiency
Spheres may have higher energy consumption due to their reduced contact with the ground, making them less energy-efficient for most practical transportation applications.
Safety Concerns
Reduced stability and control can pose safety risks, especially in emergency situations where quick and precise maneuvering is necessary.

Conclusion
While spheres may have some advantages in specific situations, such as omnidirectional movement and simplicity of design, these benefits are often outweighed by their limitations when it comes to conventional vehicles.
Wheels have evolved over centuries to provide efficient, safe, and reliable transportation, and they remain the standard choice for most land-based vehicles.
