When it rains, the tire contact area will be divided into three areas:
1. Complete floating area: the fluid pressure of water film is greater than the contact pressure between tire and ground. Lift the tread to make the tire completely off the road.
2. Incomplete contact area: Due to the extrusion of the tread, a large amount of water overflows, but a thin water film remains, and the tread is partially separated from the road surface.
3. Complete contact zone: the tread is in complete contact with the road surface.
When the vehicle reaches a certain speed (or the water film reaches a certain thickness), the complete contact zone disappears, and the tire does not touch the ground at this time, forming a "Shui Piao" state. Water skiing is very dangerous. At this time, the tire lost its adhesion. In severe cases, the whole vehicle will suddenly change direction or even roll over.

Pay attention to your health
1. Air pressure is the service life of the tire, and the inflation pressure of the tire must conform to the air pressure specified by national standards for different types and specifications of tires. Be sure to check the tire pressure. Excessive or insufficient air pressure will cause abnormal wear, cracks at the bottom of the groove, cord breakage, ply delamination, tire puncture and other damage.
2. Replace the tires on the vehicle at the right time (insist on checking the tires during the first-level maintenance and second-level maintenance of the vehicle) to keep the tires evenly worn and prolong the service life; A tire with a slightly larger outer diameter should be installed on the outer wheel.
3. Do not use retreaded tires on the front wheels; Try to use vertical tires for the front wheels and horizontal tires for the rear wheels.
