This document discusses airless or non-pneumatic tires as an alternative to traditional pneumatic tires. It notes the drawbacks of pneumatic tires like punctures and blowouts. Airless tires are not supported by air pressure and instead use flexible treads and shear bands that deform temporarily over spokes and return to their initial shape. The document reviews different design approaches from companies like NASA, Michelin, and Bridgestone. It lists advantages like eliminating leaks and punctures but also disadvantages like lack of adjustability and higher costs compared to pneumatic tires. Potential applications mentioned include military vehicles, ATVs, and small vehicles.
Blend
Up to 30 ingredients are used in your tyre’s rubber blend. The ingredient proportions will depend on what the performance goals of the tyre will be. It’s composed of several types of rubber, fillers and other ingredients, mixed in giant blenders known as Banbury mixers. These create a black gummy compound that’ll be sent on for
milling.
