What to do when aquaplaning? - Good tires minimize risks

Aquaplaning: when tires slip on wet roads and it is virtually impossible to maneuver the car, it’s a nightmare for drivers. We will explain what you can do and why a good tire minimizes the risk considerably.

What happens when you come across aquaplaning?

Water on the road normally flows through the grooves of the tire tread outward. However, if the road is very wet, the water does not escape completely. The car tire splashes the water to the front like the Doppler effect. In the end, if the amount of water is too much, the liquid forms like a wedge between the tire and the road. The tire then loses contact with the road. As a result, the brakes and the steering movements have almost no effect. If only one tire slips, the driver can steer the car in the opposite direction. If the vehicle is equipped with ESP (Electronic Stability Control), the system will automatically turn on as soon as it comes into contact with the road. If the two front wheels are affected, the rear wheels that still stick to the ground keep the car moving. If all the wheels are slipping at the same time, the behavior of the car will depend on the center of gravity and the direction taken. On a straight path, the chances are good. The worst case scenario would be if both rear wheels are affected, then the car will inevitably slide.

Impact of the car tire on aquaplaning

It depends on the tire, apart from the climatic conditions, whether aquaplaning exists. The flatter the tread of the tire, the faster it slides. The ADAC gives 3.5 mm as a guide. If the depth of the tread is less, the risk of slipping increases drastically. Therefore, if possible, all tires should have an adequate drawing depth. If there are differences between the individual tires, the tires with the deepest tread must be mounted on the rear axle. Several uncomfortable consequences may arise here in case of aquaplaning. From a purely statistical point of view, wide tires are more likely to be affected by aquaplaning than their narrower counterparts, despite the special treads designed to prevent it. The risk increases the more worn the wide tires are. The pressure of the tires also influences the slide. If the air pressure is too low, the pressure at which the tire rests on the road surface decreases (contact pressure). Then water is easier to interpose.

How else can I handle aquaplaning?

The most reasonable recommendation is to adjust your speed. If you travel slower in humid conditions, the risk reduces considerably. Worn dampers do not press the tire with the same force on the road. The risk of water intervention increases. The weight of the vehicle has no effect. If there are visible traces on the road, you must drive with caution. A lot of water accumulates in the wells. Also be careful in depressions and underpasses.

Handle even if it's too late.

Even those who follow all the tips are not one hundred percent immune to aquaplaning. If this happens, keep the following tips in mind:

• Avoid braking as much as possible: braking can prolong the time of slipping. If one wheel achieves traction while the others continue to slide, the car deforms.

• Do not drive so fast: the effect is the same as when braking: the car can deform. Guide gently in the opposite direction and then keep the steering wheel straight.

• Disconnect and let the car roll until you have control again.
