For YOKOHAMA wheel, design is the most important element. Even though it boasts light weight and high strength, it is meaningless if the key design is bad. However, it is also a wheel that can not seek out design freedom with design freedom. It is required to pursue the maximum dynamism among each inch after ensuring the fender clearance and caliper clearance of the installed car.
It has no meaning for rendering (design painting) that seems to be far from the final design. Currently the design of the YOKOHAMA wheel is starting from CAD drawings from the beginning. CAD drawing → 3D-CG → mock-up model, the design is thoroughly packed up to the final shape.
And development policy is to never change the determined design until it is commercialized. This is because there is a belief that it is meaningful to make a wheel only when connecting the goodness of the design with the product that the user actually takes.
