Bridgestone Aircraft Radial Tyres Mounted on First Production

Bridgestone Corporation, headquartered in Tokyo, is the world’s largest tyre
and rubber company. In addition to tyres for use in wide variety of
applications, it manufactures a broad range of diversified products, which
include industrial rubber and chemical products and sporting goods. Its
products are sold in over 150 nations and territories around the world.
Bridgestone Corporation announced today that aircraft radial tyres
produced by Bridgestone Corporation were installed on the first A380
next-generation super-jumbo jetliner produced by Airbus S.A.S. (president:
Mr. Thomas Enders; headquarters: Toulouse, France) and delivered to
Singapore Airlines for flight service between Singapore and Sydney starting
October 25. Airline companies around the world, including Qantas Airways,
will also operate Airbus A380 aircraft mounted with Bridgestone aircraft
radial tyres that boast superb safety and fuel efficiency.
Aircraft tyres are subjected to harsh operating conditions imposed by
repeated takeoffs and landings, while supporting heavy passenger airliners
traveling at high speeds. As such, the development of aircraft tyres requires
a tyre manufacturer to apply advanced technologies across the board. To
ensure higher safety and fuel efficiency for Airbus A380 passenger jetliners
that take off and land at speeds of up to 370 km/h and with takeoff gross
weights of up to 560 tons, Bridgestone supplies aircraft radial tyres
featuring the advanced radial structure (RRR*) with high elastic
modulus/strength cords.
*RRR = Revolutionarily Reinforced Radial
< Features of RRR >
1) Superior safety
During takeoff and landing, aircraft tyres can burst or their tread sections can separate if they run over
pieces of metal on a runway, potentially resulting in a serious accident. To prevent such tyre damage, RRR
technology offers the leading-edge belt construction with a high-durability for continuing to improve safety.
(1) Structure: The inner belt minimizes tyre expansion in the radial direction, while the outer belt resists
external damage.
(2) Effect: By suppressing tread tension, the RRR structure reduces the possibility of damage from
running over objects. Should the tyre be damaged, the new structure minimizes the possibility of tyre
destruction through bursting or tread separation.
2) Improved fuel economy
(1) The leading-edge belt construction with high elastic modulus/strength cords have reduced the tyre
weight at 7 to 10%, thus contributing to better fuel economy.
(2) The lighter tyre weight and the leading-edge belt construction which minimizes tyre expansion offer
improved abrasion resistance, allowing for more takeoff and landing cycles between tyre replacement.
The Bridgestone Group considers aircraft radial tyres as strategic products, and plans to actively promote
and expand sales. Bridgestone aircraft tyres, including those delivered to Airbus, are currently
manufactured at its Kurume Plant in Fukuoka Prefecture. In addition, Bridgestone is in the process of
constructing a production facility at its Tokyo Plant. This expansion will double Bridgestone's current
aircraft radial tyre production capacity by the end of 2011. The Bridgestone Group also has retread aircraft
tyre plants in North America, Europe, Asia, and Japan, and offers comprehensive products and services
combining support for both new and retread tyres
