Every once in a while a new prototype tire that aims to revolutionize the industry based on two specific keys appears: without air and be 100% free of punctures . Virtually all major prototypes have already advocated such as Bridgestone, Hankook, Michelin and so on. Ideas that generate much excitement for one simple reason, nobody likes a puncture having to get off the car to change the spare wheel – if you are lucky enough to have it – and go to a workshop to repair the tire. Luckily , and once again he added that fortunately, moment our tires continue pricking .
The birth of the tire with air chamber arose for reasons such as vehicle comfort that equipase. Why we would do without such progress?
At the end of the century XIX technology used in the construction of wheels, starting with bicycles, lived a revolution after another. Revolutions as the first tire itself, based on rubber and filler air, designed by John Boyd Dunlop for trike that his son went to school. Later they reach new solutions, such as radial tire Michelin, simpler tire mounting and dismounting and solutions that gradually were making bikes and first cars, which began to become popular in European cities, could move more comfort and security.
Do you really want to use tubeless tires, which are not pinched?
Even the Run Flat, so popular in recent years for its proliferation in the premium manufacturers have had to deal with the problems of ensuring that a tire to maintain its structure with low pressure.
This is a trick question. Nobody likes to suffer a puncture, especially in this time when more and more modern cars which ignore temporary spare wheel, and almost none equipped and full spare wheel. Still, we can not forget that air chamber has a reason for being .
In recent years has greatly increased the use of type Run-Flat tires. And in those years we have also seen the pros and cons of this technology, which have become popular especially premium manufacturers. To start the Run Flat are not infallible . They are able to walk a limited distance with a puncture in the tread, but a blowout or a cut on the side, which are relatively rare events, but not impossible, you may end up with our car on a crane (see story of Consumer Reports ), as set equipped with run-flat tires on a car amounts to dispense with the spare wheel.
Over time, the discomforts of the Run Flat also become diminished by the development of new tires, and the experience of manufacturers who, like BMW suffered in the flesh the peculiarities of technology. For a tire to support the weight of the car having lost pressure by a puncture, it is necessary that the flanks and the inner structure of the tire be strengthened. And get those reinforcements necessarily generate discomfort in some cases easily discernible when the asphalt is irregular, or steps on gravel or small bumps. And I say that technology has improved, and that the work of the manufacturers on the suspensions of their cars to mitigate these inconveniences has taken effect.
The difficulty lies precisely in getting a “tire” with internal structure designed to dispense air, enjoy the same benefits as a real tire.
Still, the mere fact that we have lived these experiences and should lead us to the explanation of the statement on the title of this article. The idea proposed by manufacturers based on design structures that keep the geometry flat tire . That necessarily means that their properties are altered in any way.
The real challenge will get no air, the tire enjoy flexibility in both its internal structure and its tread, at least comparable to that of a tire chamber air. The distribution of forces, for example on impact with an obstacle on the road, is homogeneous. Also not affected other properties such as durability, performance (lateral grip, braking distance, etc.), its sound and efficiency, based on the rolling resistance.
Having said which, until a “tire” no air can enjoy the same qualities as a tire itself, this technology will still be far from the market, at least for tourism. In fact, industry in which these “tires” without air could themselves find their place would be precisely that of civil engineering applications and machinery , which by its requirements or its critical function, would make a better use of these solutions.
