We should drive slowly because water is a lubrian. A lubrian is a substance that lessens the friction of a substance. Friction helps in breaks but if there is no friction you would not be able to stop the car easily and would eventually be in danger. -Avi Shah-
Your vehicle owner's manual has tire inspection or replacement recommendations but your tires should be replaced if they are over 5 years old or the remaining tread is 5/32" for driving in snow, 4/32" for driving on wet roads and 2/32" for driving on dry roads.
some times because there is oil on the road from cars driving on them and when it gets wet it becomes slippery.
If you are driving on wet roads there is no way to avoid those effects. Most brakes dry out very quickly when applied.
The amount of friction is reduced. That is one thing that keeps the tires on the road.
On a 2003 Ford Expedition : If you are driving on paved roads that are dry , for the best gas mileage , 2H But , you can also use A4WD ( Automatic four wheel drive ) on dry pavement A4WD is best for wet roads , snow , gravel because if the back wheels " slip " then some of the power is transferred to the front wheels
When driving on wet roads, light reflects off the surface of the water, causing glare and reducing visibility. This can make it harder to see clearly and judge distances, as well as increase the risk of accidents due to decreased visibility. Using headlights and driving more cautiously can help improve visibility in these conditions.
Traction on wet roads can be improved by driving with tires that have good tread depth and are properly inflated, as they enhance grip and channel water away from the contact surface. Additionally, reducing speed and avoiding abrupt maneuvers can help maintain control. Using all-season or specialized wet-weather tires can also significantly enhance traction in rainy conditions.
Smooth tires are bad for driving on wet roads because they have less traction and grip on the slippery surface, increasing the risk of skidding and losing control of the vehicle. The lack of tread patterns on smooth tires also makes it harder for water to be dispersed, leading to a higher chance of hydroplaning.
I believe you mean "Why are wet roads more dangerous than dry roads to cars?"The answer is relatively simple. Safe roads have a good amount of friction in order to let the car steer safely. On a wet road, much of the friction is reduced, not only hindering steering, but rendering brakes ineffective.
Since it takes further to stop on a wet roadway you should slow down and increase your following distance
If you're running on dry roads, there's no real need to have it on. TCS is intended more for wet and slippery roads.
They won't provide more traction when the roads are wet, it would be like driving on ice.
