Puncture proof tyres are said to be increasing demand – despite criticism from recycling associations of such products. In line with this trend, according to media reports Hankook is significantly expanding its self-sealing production capacity in China.
As of this month, 15 million tyres featuring ContiSeal self-sealing technology have been produced at the Continental factory in Lousado, Portugal. The 15 millionth tyre, a size 255/45 R 19 ContiSportContact 5 SUV destined for original equipment fitment on a Volkswagen, was produced on 23 July and gave cause for a minor celebration at the plant.
Arlanxeo, a global manufacturer of synthetic elastomers, has developed a rubber compound that can be used in the future to seal tyres. This solution for so-called self-sealing tyres replaces the spare wheel and also presents an alternative to a repair kit or run-flat tyre. An appropriate rubber compound from Arlanxeo, which is applied on the interior of the vehicle tyre, enables holes occurring in the tyre to be automatically sealed, so the driver can continue driving.
More Hankook Tire news, again from the IAA in Frankfurt. The tyre maker reports that its first self-sealing tyre, the newly-developed Ventus Prime² SEALGUARD, will be supplied to Volkswagen as an original equipment tyre. The first VW to be shipped with the self-sealing tyre is the Touran, which will wear the Ventus Prime² SEALGUARD in size 215/55R17.
