NAlicia of water on the surface of the roads complicates the operation of the vehicle. In the Ukrainian reality the risk of aquaplaning increases due to the ruts on the road surface. To help avoid problems on the road will help careful driving and tires with good tread.
When you are driving on dry roads, the tire thinking is not necessary. However, the situation may change dramatically, if you break out the thunder and heavy summer rain will cover the road film of water. This can dramatically affect the handling: it is difficult to control the car, especially if the tyres are in poor condition or worn out. The best weapon against aquaplaning are new tires. They can’t completely eliminate the risk of losing contact with the road, but will allow you to control the car until then, until you change speed to adapt to the new conditions.
Loss of control
From the point of view of traffic safety, the vehicle must be fitted with tyres with correct tread depth and characteristics corresponding to the prevailing weather conditions. If on the road a lot of water, at a certain speed protector no longer pushes aside the water from the contact patch, resulting in contact with the road is lost and the clutch will disappear.
If the tread depth is less than 4 mm, the wet grip is reduced, which naturally leads to the risk of aquaplaning. Moreover, the braking distance becomes longer and the car starts to slide.
Held by Nokian Tyres test show that on a worn-out tyre (tread less than 1.6 mm), the danger of hydroplaning occurs at a speed of 75 km/h, while for new tyres, the figure is 88 km/h.
“If you notice that your car “floated”, remove your foot off the throttle and squeeze the clutch. In any case, do not brake, and do not make sudden movements while driving. As the process of reducing the speed has already started, the traction will recover quickly. And when that happens, your tires must be aimed in the right direction, not across a stream of cars”, says Matti morri, Manager of technical support Department of the concern Nokian Tyres.
Loss of tire contact with the road
When using waste tires the contact area between the tyre and the road decreases sharply with increasing speed. As a result of research carried out by the Finnish experts, with the water layer of 3 mm and a speed of 75 km/h the contact patch an old tire with tread of 1.6 mm is only 16% of the contact patch standing on the car seat.
The wear indicator
To easily control the thickness of the tread, the company Nokian Tyres has developed a simple and effective wear indicator DSI (Driving Safety Indicator), which is located on the centre rib of the tyre. It shows the residual depth of the tread grooves in millimeters. As wear of the tread, the numbers are erased. Driver easy to understand when the tyres are already worn out and it is time to change to a new one. Indicator of aquaplaning in the form of drops shows when the bus stops being safe on wet roads.
In rainy weather to avoid hydroplaning will help 5 simple rules:
- Check the tread depth of the tires. We recommend a minimum tread depth of 4 mm.
- Check the tire pressure. Car on under-inflated tires are worse managed and consumes more fuel.
- Bring the speed in line with the weather conditions. In the pouring rain she should be 15-20 km/h lower than when driving on dry asphalt.
- Operate the machine safely. Maintain a safe distance and obey the speed limit.
• Check the condition of the road. Try not to use a track, as it is water.
