Why your car's wheels aren't solid blocks of rubber
In short: Most people assume air is just a filler, but it is actually a sophisticated engineering choice. This video explains why pneumatic tires became the global standard and how they function as an essential part of a vehicle’s suspension.
While solid tires exist, they are often extremely heavy compared to their pneumatic counterparts. Compressed air allows for a balance between supporting a vehicle's weight and maintaining necessary flexibility. This interaction directly dictates the ride's comfort, handling capabilities, and overall safety.
Engineers view tires as an integral component of a vehicle’s suspension system rather than just a rolling surface. The video also explores the current technological shift toward airless tires, which aim to solve the persistent issue of flat tires without sacrificing these mechanical benefits.
