What are the benefits of having larger front wheels and smaller rear wheels?

[VanRafael]

Front wheels are responsible for steering, and smaller wheels have less friction, which has less impact on speed. Rear wheels rely on friction to drive the vehicle, so the rear wheels are slightly larger. Having smaller front wheels and larger rear wheels provides better climbing power, higher safety performance, and lighter steering for easier turning. Here is additional information: Rear wheels: Rear wheels are the driving wheels, while front wheels are the steering wheels. Besides steering, the front wheels only need to bear the weight of the diesel engine, with essentially no other tasks, so there is no need for them to be very large. On the other hand, rear wheels are the driving wheels. For example, tractors are characterized by strong towing capacity. Diesel engines inherently have high torque, and with the addition of high and low speeds in the transmission, the torque amplification in low gear is quite powerful, allowing the vehicle to easily pull several tons of cargo.
