Tire Testing and Evaluation
Yokohama Off-Highway Tires has an extensive tire testing & evaluation system:
Abaqus Finite Element Software
We employ advanced Abaqus Finite Element Software to design and test tires virtually. The Abaqus system enables engineers to test the tire’s movement, stress and other factors that affect it while in motion. This method of modeling of tires goes a long way in engineering innovative tires.
International Testing Institutions
All our tests are based on the strict international standards. Our tires are also tested by top independent testing laboratories, including Germany’s world-renowned “TUV”.
Our tire testing and evaluation experts get constant feedback from the market, from OEM engineers to equipment operators resulting in continuous improvement.
All tires are carefully tested for more than 500 possible defects and classified accordingly.
Analysis of New Tires Structure
Tire Modeling from Structural Analysis to Real-Time Applications
Tire Stiffness Testing – Radial Stiffness & Lateral Stiffness
Special fully computer-controlled test bench.
Tire Footprint Analysis
Important tire characteristics obtained from the same test device.
Outdoor Testing – Traction Slip
Tire traction/slip characteristics under the real field conditions.
Outdoor Testing – Traction Characteristics – Single Wheel Tester
We conduct indoor and outdoors tests, as well as special tests, for agricultural tires. After rigorous testing on specialized equipment, the tires are tested in farm fields for final evaluation.
Special Tests: Conducted On A Case-to-Case Basis
- Machine’s tilt test
- Braking test
- Machine stability test
- Mobility testing
- Real endurance testing
The company’s in-house quality assurance and testing program is backed up by a set of test wheel machines for static and dynamic test tires.
- Permanent high-speed and endurance tire testing
- Indoor testing in TUV
Environmental Compliance and Protection
We strongly believe in minimizing the impact of our operations on the environment. At all our locations we strictly meet and often exceed local regulations regarding environmental protection. At each of our manufacturing locations, we strive to minimize the environmental impact of its operations via
- Deploying state of the art pollution and emission control and reduction equipment such as Green belt, effective carbon handling and rain water harvesting to name a few.
- Using only REACH compliant raw material and low aromatic oils in its manufacturing processes.
- IFC (Washington D.C.) environment & social responsibility survey.
- Striving to minimize energy consumption in the manufacturing process.
- We are proud of the fact that our facility is one of the most energy efficient tire plants in the world.
