Wheel for car, has transverse and longitudinal tire section and slanting section trough, where tires with lower side surface have contact with road when vehicle needs more friction force during fast starting, braking and driving in curves

摘要

The wheel has a transverse and longitudinal tire section (6) and a slanting section trough (3), where the section and the trough make tires stable. The small part of the tire surface has contact with the road, where the tires with lower side surface have the contact with the road, when a vehicle needs more friction force during fast starting, braking and driving in curves.
