In 1980, making full use of the design, technology and manufacturing equipment and developed in Japan and overseas for railway wheels, including those used for Japan's Shinkansen bullet train, we developed Japan's first forged aluminum wheels for trucks and buses. Currently, along with the aluminum wheels we supply for trucks and buses, our aluminum wheels for special vehicles in new transportation systems all receive high evaluations in the market. We began marketing its high-brilliance aluminum wheel "Tough Bright" in April 2005. The brilliance of this wheel is 30% higher than conventional products. Also, in 2010, we began marketing an aluminum wheel used in all vehicles that met Post New Long-term Regulations for exhaust gas emissions. We had quickly developed this wheel, the lightest aluminum wheel in the world (indicated by our own survey), to meet new ISO standards. This environmentally friendly ultra-light aluminum wheel has been recognized for its effectiveness in helping to reduce CO2emissions in truck transportation.
And , our alminum wheels have toughness which exceed MLIT technical standard(JWL-T) substantially.
This newly launched aluminum wheel meeting new ISO standards is used by vehicles meeting Post New Long-term Regulations for exhaust gas emissions. We survey indicates that it is the lightest aluminum wheel in the world. A direct comparison shows this wheel with a weight of 167 kg/vehicle compared to a 198 kg/vehicle weight for JIS standard steel wheels. This aluminum wheel is 19.2 kg to 22 kg lighter than the current aluminum wheel meeting the JIS standard.

Use of this wheel leads to greater fuel economy and reduced CO2emissions.
Due to less weight on the springs, use of this aluminum wheel raises fuel efficiency by 0.7% to 2.1% over that achieved with steel wheels. (Values were obtained from tests consigned to the Japan Automobile Research institute.)
This increase in fuel efficiency can lead to an annual reduction of approximately 1.9 tons in CO2emissions. (It is calculated that the effect of using this aluminum wheel is a 1.4% reduction in fuel expenses for a truck traveling an annual distance of 180,000 Km, with a fuel efficiency of 3.5 Km/L.)
Other effects of the reduced wheel weight
include an increase in load weight, and more on-board devices.
The manufacturing method and quality control is the same as that used for railway wheels.
The strength of the wheel is well above the Ministry of Land, Infrastructure and Tourism's standard (JWL-T).
The wheel acts against retention of heat, which leads to longer use life of tires and brake linings.
The use life of tires and brake lining increases due to the lower weight below the springs, and mechanized processing for greater precision.
A full lineup is available for all types of vehicles, from mid- and large-size trucks to large and high-speed buses. In addition, new super single aluminum wheels have been brought to market.

Handling of wheels meeting new ISO standards
The wheels for trucks and buses meeting Post New Long-term Regulations for exhaust gas emissions will be changed to types that meet new ISO standards. New ISO type wheels and JIS type wheels are not compatible. Please handle these wheels correctly after consulting with your wheel dealer about the differences. Inappropriate use or handling of the wheels can lead to serious accidents..
