Tyre innovation is moving fast, and we look at the leading new tyres you need to know about.
By placing a chip into the rubber, Goodyear-Dunlop declares that tyres will be able to communicate with the automobile – speaking to the electronic control unit and anti-lock brakes, for example – to adapt to the road conditions. The batteryless chip tells the vehicle what sort of tyre is fitted, and passes on atmospheric pressure and temperature to accomplish optimal braking and cornering performance.
Specific analyses of tyre status will be shown. The tech is set to debut on new vehicles initially, before being offered on the aftermarket – and the chip, fitted to the centre of a tyre’s tread, is declared to be light enough not to disturb the balance of a wheel.
Twin Air Chamber
This principle, planned for SUVs, divides the tyre’s air chamber into 2. The concept is that if one pocket leaks, drivers can continue their journey on the other at a reduced speed. The two chambers sit side-by-side, and Goodyear-Dunlop declares a benefit of the design is that the tyre has a smaller contact area with the road, with the two chambers separated by a broad groove. Plus, the maker says this groove assists to produce a reduction in the tyre’s weight, and in turn rolling resistance and fuel consumption. In spite of the lowered contact location, the brand-new style is also stated to be as safe as other tyres on the market.
Another Goodyear tyres and Dunlop innovation called Air Maintenance Innovation (or AMT) packs an electronic part into a tyre that controls air pressure. It identifies how much air remains in a tyre and tops it up automatically if necessary. This would effectively get rid of the requirement for chauffeurs to pump up their own tires – and as research has actually shown that running tyres at just a couple of psi under their recommended pressures can have a severe impact on fuel performance, this could be a real advancement. The idea was first earmarked for business vehicles, however AMT is likely to be seen in passenger cars in the future.
