This seminar presentation discusses airless tires as an alternative to traditional pneumatic tires. It provides background on tire function and properties before explaining the key features of airless tires, such as spokes that flex to provide cushioning instead of air pressure. The presentation highlights advantages of airless tires like reduced weight and improved safety. It also notes future challenges like developing materials that can withstand various road conditions and developing airless tire designs optimized for use in space and on other planets.
