Tokyo (January 12, 2010) - Bridgestone Corporation announced today that it has been selected to supply aircraft radial tires for the Mitsubishi Regional Jet (MRJ) by Sumitomo Precision Products Co.,Ltd. as Landing Gear System Integrator, the next-generation regional jet under development by Mitsubishi Aircraft Corporation.

Bridgestone's aircraft tires are already being supplied for use on large aircraft with 100 or more seats, and the supply of tires for the MRJ, a regional jet in the 70- to 90-seat class, will further expand the scope of the company's aircraft radial tire business.

The tires that Bridgestone will supply for the MRJ feature the advanced radial construction known as Revolutionarily Reinforced Radial (RRR). The features and advantages of RRR, as well as the aircraft using RRR tires, are outlined below.

1. Reduced fuel consumption and enhanced cost management
   1) The advanced radial construction with high elastic modulus/strength cords makes the tires lighter, which contributes to improved fuel efficiency and therefore a reduced environmental burden.
   2) The advanced radial construction also results in higher abrasion resistance, allowing for more landings of the aircraft before tire replacement, thus contributing to better cost control while maintaining quality.

2. Enhanced safety
   Due to RRR construction, which has outstanding durability, these tires will offer further enhancements in safety when compared to tires that do not feature the RRR construction.

1. Aircraft in operation
   1) Airbus A380 (In operation since October 2007)
   2) Boeing 777-300ER operated by ANA (In operation since October 2008)

2. Aircraft that will be introduced in the future
   1) Boeing 787 Dreamliner
   2) Airbus A350 XWB

Moving forward, Bridgestone will work to further increase the market share of its RRR tires as well as its other aircraft radial tires, all while striving to make an ever greater contributions to customers.
