Revolutionary Self-Repairing Tyres Could Make Flat Tyres History

The flat tyre is predestined to become a distant memory, with Michelin and Goodyear tyres working on a new tyre that repairs itself when it gets a puncture.

The self-repairing tyre can be driven over nails without losing pressure, thanks to a new rubber compound that right away plugs any holes in the tread.

The tyre is not the first to have self-healing properties – Continental released comparable innovation in 2009 – however, Michelin says early variations of self-repairing tyres struggled to provide the same performance as undamaged tyres, with the compound sinking to the bottom of the tyre if an automobile was parked for any length of time. This would produce vibrations and affect rolling resistance, increasing fuel usage.

The company refuses to hypothesize on when the innovation will make it to market or what it costs? However, it is stated the tyres will be superior to run-flats because they can be driven at normal speeds if they’re punctured and they provide better ride convenience. Run-flats are created with very stiff sidewalls so that they can continue to be driven without air.

The disadvantage is they don’t absorb bumps too.

Run-flats have failed to get a foothold in the market, with just BMW making a significant dedication to the technology.

Michelin managing partner Didier Miraton states the puncture proof tyres have big potential, particularly in southeast Asia with its rough roads.

Self-repairing tyres have substantial attract automobile makers as they permit them to get rid of the extra tyre from their cars and trucks, saving weight, enhancing fuel performance and maximizing boot space. A variety of car makers – including Holden on its Commodore – have puncture repair packages as basic equipment in lieu of an extra tyre.

Michelin approximates the removal of the extra tyre can save approximately 30 kilograms and maximize another 80 litres of boot area, along with reducing fuel usage and CO2 emissions.

The company states the tyre likewise has consumer advantages, as drivers do not like the inconvenience – and in some cases risk – of changing to a new tyre on the side of the highway.

It declares the innovation will likely yield environmental benefits, as less tyres will have to be manufactured to cover an offered range.
