Waiba tire principle

Due to the load of the vehicle, inertia and other reasons, the inclination angle must be set in advance. Trucks are generally V-shaped, with eight sides inside and eight sides outside. Cars are generally eight-character, and the eight-character is negative and extroverted.

This design, first, can better provide the grip of the vehicle when turning at high speed and prevent rollover. When the front wheel drives the steering, the rear wheel shakes its tail. Because the two tire treads of the rear wheel are vertical, they can't all touch the road surface, while the eight outer tires all touch the road surface due to camber pressure to increase the grip. Second, because the vehicle's center of gravity is relatively reduced, the resistance is reduced, and the dynamic performance is also improved to a certain extent.
