Testing & Development
Testing & Development
Passion for innovation is a key part of our engineering culture at Yokohama. In this section of our website we would like to showcase exciting breakthrough technology. These innovations allow us to provide our customers the expected tire performance and value to achieve ultimate driving enjoyment.
Every year, Yokohama conducts Ride & Drives for its dealers across the country. The program offers us an opportunity to test our products outside of the lab. Watch the video here of an actual Ride & Drive held at the Cheney Stadium in Seattle, Washington.
Yokohama opens Ride & Drives to enthusiasts! Consumers learn firsthand how various Yokohama tires feel during a special Ride & Drive at the Qualcomm Stadium in San Diego, California. Click here to watch the video.
Every day we see breakthrough technology in electronics for personal use. Yokohama employs the most advanced high speed computing technology to provide our engineers rapid and very detailed design evaluations thorough computer simulations. This is like the ultimate virtual reality show for design engineers. Rapid prototyping, multiple factor analysis, molecular level evaluations etc. are now at the disposal of our design team real time. This means we can deliver tires to the market quickly with technology incorporating the latest science and engineering globally.
Water Evacuation Simulation
Traction on wet road surfaces is an important part of the product safety we deliver to you in our tires. Simulation of hydraulic flow, dynamic tread pattern and groove geometry, water film layer properties etc. results in real world prediction of macro and microscopic road contact characteristics which equals gripping performance. We maximize the water flow through the footprint at various speeds, minimizing white areas “little or no contact” at higher speeds.
Tread Wear Simulation
Tread wear mileage is an important part of the product value we deliver to you in our tires. Simulation of the road contact area, tread design elements, multiple axis tire dynamic loading, tread compound properties, tire internal structure etc. results in real world prediction of friction and abrasion characteristics between the tire and road surface which equals tread wear performance. We minimize the red/yellow shading end of the scale which indicates higher abrasion.
Rolling Resistance Simulation
Fuel consumption while rolling is an important part of the product value and environmental impact we deliver to you in our tires. Simulation of heat generation from tire structural bending, compound hysteresis, and tire mass conservation etc. results in real world prediction of rolling resistance force which equals fuel consumption. We minimize the higher temperature, red/yellow areas within the tire at highway speed which equals energy loss.
Simulation of the air flow around the tire influenced by the tire profile geometry, sidewall design elements etc. results in real world prediction of tire aerodynamic drag which also equals fuel consumption. We minimize the turbulence lines or flow resistance red/yellow areas which equals drag force.
