3D printed tyres that never need replacing

Most tyres will need to be replaced about every five years, however a new 3D printed tyre from Michelin may one day outlast your vehicle. While traditional rubber tyres gradually lose their tread as a result of friction, the prototype uses 3D printers to replenish this tread as needed. A series of sensors built into the tyre monitor the tread wear and provide information about performance and maintenance. This information is relayed to you via an app, and you can then order 3D printed tread replacements. https://www.digitaltrends.com/cool-tech/3d-printed-tire-michelin-concept/
