How polished grooves in all-season tires can help to prevent hydroplaning

all-season tires

When driving in wet conditions with all-season tires on your vehicle, you want to make sure that you have tires that are good in these conditions. Wet conditions tend to be to most challenging driving conditions during the warm season. During wet conditions, you have both the challenge of heavy thunderstorms with very heavy rain, which can cause difficulties by itself. In addition, you will need to adjust your speed and ensure that your windshield wipers can keep the windshield clear for an unobstructed view.

During the heavy rain and after, you can have issues with hydroplaning, as you have a lot of water present on the road surface. You can also have large shallow puddles during and after heavy rain, which can easily cause the car to show symptoms of hydroplaning. Therefore, you want the tires to have both a good wet grip and the prevention of hydroplaning. Hydroplaning is scary and involves the loss of contact with the road surface. It is also the tire’s tread depth and speed associated with the tire’s inherent ability to both displace and store water in the tread. The wet grip is related to how well the tires can create grip and traction on wet roads that are more slippery than dry roads. Tires are often tested for their wet grip by testing their braking distance on wet road surfaces. As the grip is reduced and the braking distance is prolonged, you need to adjust your speed and keep an adequate distance from the vehicles in front of you.

The use of polished grooves is something that Nokian Tires introduced as a way to reduce the occurrence of hydroplaning. The polished grooves speed up the water flow in the grooves as it reduces friction and the occurrence of turbulence. By moving the water away from the road surface more effectively, the tires can reduce the risk that the tires would lose contact with the road surface.  You can find polished grooves on the Nokian zLine A/S. They have proven to be a very valuable innovation in the strive to constantly make their tires safer in any conditions. They have also launched some other innovations to their tires.

The new Nokian Tyres One has high-volume pockets integrated into the tread to allow for more water to be stored and uses functional siping to make sure that the water is flowing to the sides of the tires. The tread depth is important when it comes to hydroplaning, and you need to make sure that you have enough remaining tread depth and that you don’t go below 5/32 inches to ensure that the grooves can hold and transport enough water. The speed also has a significant impact; the newer tires you have, the faster you can drive, while with tires that are close to being worn out, you really have to be careful with your driving speed.
