Different concept tyres worth knowing
The tyre world is always dynamic. New things are happening in the sector on every day. Tyre Asia picks up some interesting different concept tyres in the market produced by global tyre-makers and researchers.
Toyo Tire’s Noair
Toyo Tire and Rubber Company has launched an airless tyre- Noair-on a pilot basis. The company is yet to decide when to commercially launch the tyre in the market. Noair tyre features 50 sets of cross-shaped resin supporting rods lined up in a circle in place of air to bolster the weight of a vehicle and absorb shocks from the road. The company has been working on the product since 2006 to improve durability and reduce noise.
Harvard John A Paulson School of Engineering and Applied Sciences (SEAS) researchers in the US created self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing. Engineering self-healing properties in dry materials – such as rubber – has proven more challenging because rubber is made of polymers often connected by permanent, covalent bonds. In order to make a rubber self-healable, the team needed to make the bonds connecting the polymers reversible, so that the bonds could break and reform.
Pirelli’s new-gen Cinturato P7 blue tyre
Pirelli has introduced the new generation of Cinturato P7 Blue tyres. Originally launched in 2012, the Cinturato P7 Blue was the first tyre in the world to claim a maximum score on the European tyre label for energy efficiency and safety (in certain sizes). The new version of Cinturato P7 Blue reduces rolling resistance with a subsequent benefit in terms of fuel saving and CO2 emissions reduction, helping the environment.
Michelin’s 3D-printed, airless tyre
Michelin has unveiled puncture-free, 3D-printed tyre made entirely of recycled materials, and it too can be recycled at the end of its life. The ruggedness of the tyre comes from its biometric structure, taking influence from the honeycomb. The tyre gets its strength from its coral-like texture.
Goodyear’s spherical tyres
Goodyear has in its kitty a sphere-shaped tyre that could make driverless cars safer and smoother. The Eagle-360 would allow a car to move in all directions, making it easier park in tight spaces. Each spherical tyre would be suspended from the car by magnetic fields – using similar technology to magnetic levitation (maglev) trains. According to Goodyear, this will increase passenger comfort and reduce noise. Its tread would be 3D printed, and customised to suit the driver’s habits and location.
