The auto industry demands the highest standards for tire uniformity and quality. We at Kokusai provide laboratory testing for both tires and wheels, including durability and road simulator machines that properly evaluate assemblies. While all of the diagnostic tests we offer are important to maintaining the highest quality tire performance, such as rolling resistance, fatigue, durability, tread distribution, bead expansion, and road surface motion, high speed uniformity is perhaps the most valuable.
High speed uniformity testing can measure three-dimensional tire force variations unable 
to be recorded at low speeds. It can ensure full measuring of the forces acting on a tire about the radial, lateral, and tangential axes as it contacts the road. Inconsistencies that occur during the manufacturing process account for the differences among the forces.
In addition, we fully understand how vital long term usage is in tire production Thus, we utilize the highest precision machinery to also test tire longevity. All of our tire and tire/wheel uniformity capabilities, when listed, include:
- High speed uniformity
- Low speed uniformity
- Balance
- Runout
As a world leader in testing and balancing machinery, the quality and accuracy of the equipment in our ISO 9001:2008 certified facility is unparalleled. Some of our control manufacturers include Allen Bradley, Mitsubishi, and Pro-Face.
