Sumitomo’s new Enasave Next tire has 50% lower rolling resistance

Filed under: Tires — Notch @ 6:46 am

In September, Sumitomo Rubber Industries launched a new flagship product for its Dunlop-brand Enasave series of fuel-efficient tires. The new tire, which is currently offered only in Japan, achieved an ‘AAA-a’ rank under the Japanese tire labeling program, the highest rating possible for rolling resistance and wet grip. Sumitomo says the new tire has 50% lower rolling resistance than the standard Japanese replacement market Dunlop tire that the company introduced in 2008, the year it set out to achieve this goal. Sumitomo met another of its long term goals in November 2013, when it introduced the Dunlop Enasave 100, an entirely fossil-free tire, at the Tokyo Motor Show.

Goodyear plans to produce tires using silica produced from rice hull ash

Filed under: Carbon Black, Silica, Tires — Notch @ 6:30 am

According to Rubber News, Goodyear plans to produce plans to use silica derived from rice husk ash to produce low rolling resistance tires. The ash is a waste-product from the burning of rice husks to produce electricity. Goodyear reportedly has tested silica derived from rice husk ash over the past two years at its Innovation Center in Akron and found that the material’s effect on tire performance was “equal to traditional sources.” Goodyear is reportedly in the process of negotiating with potential suppliers to purchase silica produced from rice hull ash.

“The use of rice husk ash will provide Goodyear an alternative source of silica while helping reduce the amount of rice husk waste being landfilled,” said Joseph Zekoski, interim chief technical officer. “This illustrates Goodyear’s commitment to innovation and to the environment.”

Last year, Pirelli announced that it was planning to use rice hull ash silica in its tires, while Bridgestone has committed to begin production of plant-derived tires by 2020.

Dunlop Aircraft Tyres to open first retread facility in the US

Filed under: Rubber, Tires — Notch @ 6:10 am

Dunlop Aircraft Tyres, a UK-based aircraft manufacturer and retreader, has announced plans to establish its first retreading facility in the United States. The facility will focus on retreading popular narrow and wide-bodied jet airliners and military aircraft, and will also distribute new aircraft tires. Until now, Dunlop has been supported by independent distribution and retreading partners in the Americas who distribute new tires and retread the company’s tire casings for regional turboprops and jets. According to the company, by offering local retreading within the region, Dunlop can bring increased choice to airlines, military aircraft operators and maintenance, repair and overhaul facilities. Dunlop is currently evaluating a number of potential sites in the South East of the USA and is planning to open the facility in early 2016. In 2009, Dunlop Aircraft Tyres opened a similar tyre distribution and retreading facility in China. It now employs nearly 60 people and supports airlines across Asia Pacific.
