Recently Michelin has teamed up with General Motors (GM) to conduct a test of tires that cannot be punctured or damaged by UPTIS (Unique Puncture-proof Tire System). In fact, airless tire technology is no longer new because it has been commercially produced by Michelin for several other tire manufacturers. However, with the Chevrolet Bolt electric cars being tested for new tires, the future of passenger cars will have the option of adding non-air tires. According to GM's plan, that time will be in 2024.
As you can see in the video or this type of UPTIS tire is made up of an outer surface made of rubber and has a pattern like a regular tire. The difference is that it does not contain internal air like traditional tires that use rubber zones to absorb force. It can also be flexibly deformed according to the terrain that the tire surface impacts.
As a result, the main advantage of this tire is that it does not have to worry about intestinal puncture and limit local wear compared to traditional tires. Since then, UPTIS has a longer life cycle, contributing to saving tire maintenance costs, repairing or replacing tires when damaged or worn out. At the same time, GM said that when it comes to airless tires, its models will be significantly lighter thanks to new lighter tires and no need for spare tires.
From the perspective of environmental protection, new tires will indirectly help reduce the amount of tires removed, followed by a reduction in emissions, materials used for tire production. Michelin estimates that 20% of the world's tires are discarded annually due to irregular puncture and wear. The number of 200 million discarded tires every year is really a nightmare for garbage and pollution.
