Japan invented cheap permanent tiresAugust 31, 2020
Japanese company Omikenshi has unveiled a new material that will halve the price of run-flat tires and make them more environmentally friendly, according to the Nikkei newspaper.
Recall that thanks to the use of run-flat technology, the car is able to drive several tens of kilometers even after a serious tire puncture, when there is no more pressure in the tire. Thanks to this, you can get to the nearest tire workshop, so that car companies do not equip cars with such tires with a spare wheel. However, such wheels have a number of disadvantages, the most significant of which is their high price.
But the Japanese company Omikenshi announced that it has found an alternative to cellulose fiber used in such rubber. Cellulose fiber is textile cords woven into one of the layers of the tire. This component is more heat resistant than the polyester layer in standard tires. But it also costs significantly more. The secret of an alternative inexpensive material has not been disclosed, but it is reported that specialists from Shinshu University and the Japanese company Zeon, which specializes in the production of various chemical products, including synthetic rubbers, took part in its development.
According to the developers, the new fiber costs about 2 times less, moreover, it can significantly reduce the production process time and reduce carbon emissions by more than 50% compared to high-strength viscose. It is noted that the launch of serial production of such tires is scheduled for the 2021 fiscal year.
