Researchers at Oregon State University have found that plant fiber based microcrystalline cellulose can effectively replace silica in tires, and the environmentally friendly change could even drive tire costs lower, with increased fuel efficiency, without compromising on performance. The study found that tires manufactured with microcrystalline cellulose increased heat resistance of the tires while retaining their tensile strength.
The tires’ grip on wet road conditions remained unaffected, and the rolling resistance in case of dry roads also showed a decrease. And since the energy intensive carbon black and silica were removed, the tires required less energy for production. While the short term effects of the process look all good, researchers have yet to confirm the long term durability of these tires.
