Why was the invention of pneumatic tyres significant?

The invention of pneumatic tyres was significant primarily because they greatly enhanced the comfort level of riding bicycles compared to solid rubber tyres. Pneumatic tyres are designed to be inflated with air, which allows them to absorb shocks and bumps from the road surface. This cushioning effect significantly improves the ride quality, making it more pleasant for cyclists over uneven terrains.

When comparing pneumatic tyres to solid rubber tyres, the latter can feel harsh and unforgiving, leading to discomfort during rides. By providing a softer, more adaptable contact with the ground, pneumatic tyres reduce the vibrations that are transmitted to the rider, enabling longer and more enjoyable rides. Additionally, this innovation also contributed to better grip, traction, and handling of bicycles, further enhancing the overall riding experience.

While the other options highlight some interesting aspects of bicycles, such as speed, production ease, and weight, they do not capture the primary significance of pneumatic tyres in terms of rider comfort and experience.
