General Motors and Michelin reported that they are cooperating in the development of airless rubber technology. The companies have already presented the fruit of cooperation – airless tires Uptis (The only system for tire loss), which will be tested on electric vehicles Chevrolet Bolt.
Uptis (Single tire loss-free system, translated as "single tire pneumatic system") includes an external protector and a soft edge, among which are "slings" made of a composite rubber compound and polymeric fiberglass.
The technology for the insane tire is used by the Michelin Tweel tires, which were introduced in 2005. Later, the company began selling such tires – for use in construction and agricultural machinery.
GM expects that in case of successful testing of Uptis, the airless tires will begin to be used on passenger cars by 2024.
