Do bigger wheels mean better fuel consumption?

No, bigger wheels generally do not mean better fuel consumption. In fact, the opposite may be true. Larger wheels typically have more mass than smaller wheels, and this can increase rotational inertia, which can lead to increased fuel consumption. Additionally, larger wheels can require more power to turn, which can also reduce fuel efficiency.

Smaller wheels are more fuel efficient due to reduced rotational inertia and less resistance from the road. Smaller wheels also have a reduced circumference, which means the engine does not have to rotate as many times to cover the same distance. This can lead to improved acceleration and fuel efficiency.

However, it's important to note that the impact of wheel size on fuel consumption can be influenced by several other factors, such as the vehicle's overall design, weight, engine efficiency, and driving conditions.
