The anti-puncture tire begins its final phase of development

The most demanding test of a tire is driving over studs.  It is impressive to the naked eye, but it is a very interesting solution

If cars no longer need gasoline or diesel to function, and in a few years they will not need a driver to circulate, many other things could no longer be essential.

The tires seem like they could also do without air, or at least that is the idea that has been developing since 2017, but has made great progress in recent months in Michelin.

The vertical force on the tire without rolling seems to be enough to generate a greater deformation in the lower zone, compared to what is usually seen in tires with air

The concept is called Uptis, what does it mean Unique Puncture-proof Tire System or Unique puncture-proof tire system, and is developing it Michelin in conjunction with General Motors. In fact, the first tests were done with the electric Chevrolet Bolt back in 2019, as an introduction to the novel idea of ​​an airless roof.

And like many technological innovations, this concept clearly aligned with sustainability, have shunts that may not be seen with the naked eye, but they are probably more meaningful than the initial message that the idea conveys by itself.

The Michelin Uptis will be able to pass over these obstacles without major problems, due to a relative hardness at low speeds, which, however, must increase with the demand to go faster.

What would be the first conclusion about an airless tire? If it is not that it will not be pricked, it is that will not explode, but it could also be that will not deflate, or going a little further, that reduce the number of road accidents caused by sudden tire breakage.

And what does that have to do with sustainability? Except for the general benefit of save lives that today are at risk from accidents caused by tire damage, not much more is seen about it. But if you pay attention to the consequences of not having more punctures, you can see that the spare wheel will no longer be necessary, This reduces the number of tires needed for each car from 5 to 4.

But if there will be no punctures, the mechanical or hydraulic jack will not be necessary to lift the car, and that will also generate lower production of iron, aluminum and rubber, then they start to appear indirect reductions in industrially manufactured products that may no longer be needed over time.

The design is extremely complex, because as it does not have an air chamber that gives elasticity, that bending must be made by its internal components.  Vertical and lateral forces will be very high

At once, the amount of waste tires would be reduced that because they have a deep enough break, they can no longer be used in cars, and they are part of large rubber dumps that do not biodegrade. And finally, as there are no inflation pressure problems, the life of each tire will be longer, Since only by having the wheels inflated less than recommended, the tires wear out prematurely.

With these premises the project began, although it was also it was hoped to achieve a product that could be manufactured entirely with 3D printers and with 100% renewable materials, which would generate a less impact on the environment also from the construction the tire itself.

The engineering challenge is very great, because in the design of its walls and internal sheets, and in the choice of their materials and composites, are the keys to get the correct degree of adherence, stability and elasticity / stiffness to function according to the demands of vertical and horizontal weight or load, and speed.

The image of an open tire and with sheets instead of an inner tube, generates distrust.  Now comes the most difficult part, which is to give certainty of the product

It seems that they have reached a point of development that they are ready to begin the hard trials, the empirical ones, where the simulations must be validated in reality, and where different types of requirements will subject the product to physical limits than it must “Come out well off”worth the pun.

Safety must come before sustainability, then, proven its properties of environmental care, this rubber now must do millions of kilometers to decide if it is possible to be automakers original equipment by 2024.
