Airless tires, General Motors and Michelin together for puncture-proof tires
It has been talked about for some time, but we have finally come to the point. The first airless tire will be the “Michelin Uptis“, Presented in 2019 and ready to” dress ” the American electric Chevrolet Bolt. The production of airless tires is a project that has been going on for decades, but has reached a point of concreteness only recently, thanks, in this case, to the collaboration established between the French Michelin and the US General Motorswho have decided to patent this new technology on the Bolt EVone of the small cars Chevrolet next generation.
“The goal is to fit these tires on the new generation of Chevrolet Bolt and this could happen in 3 or 5 years ”, he revealed Alexis Garcinpresident of Michelin for North America. There Bolt it would be a natural choice for Michelinsince the tests on the Uptis started in 2019 right on the compact american. As for Europe, last September the French brand presented an example of the MINI Cooper SE with airless tires. Will the first European car to choose this solution be electric?
For the design of theUptis, Michelin recorded approx 50 patents in over a decade of tests in the laboratory and on roads all over the world. Gum it does not have an inner tube and its structure is based on a series of rigid fiber plates flexible glass which support the entire weight of the wheel.
The alloy wheel acts as a “reinforcement” for the rubber and cannot be removed. However, it is tire it is more deformable than the models on the market and is therefore more resistant to impacts or rough paths. It is to be believed that in a few years Michelin it will not be the only one to sell airless tires.
