Winter Tyre Test

If the safety of your car is very important to you during winter and snow, you should consider winter tyres test. Once the cold temperatures starts, it is necessary that car tyres have better grip on the roads.

Tyres help to protect the wheels from wear and tear. They make the vehicle to accelerate properly because of the high friction force between the road and the car. Winter tyres require up to 3 times the grip of average summer tyres. What winter tyres offer are improved safety and also provide better grips in wet weather, especially when temperatures are below 7 degrees.

Winter Tyre Test Features

Winter tyres are different from regular tyres, because they are specially design to perform on adverse weather road conditions, such as, slippery roads, snow, wet roads, downfall, muddy and icy roads. Winter and snow tyres are made with great handling and better traction properties.

These are some of the features of winter tyres:

Winter tyres are designed with softer rubber, these rubbers heat up quicker and can roll nicely on cold and wet roads. When temperatures are low, the rubber in tyres can become fragile and can break easily. This is the reason you should perform winter tyre test, to make sure that they are suitable for winter roads.

The external perimeter of the winter tyres should have a unique design on it, referred to as the tread. The purpose of tyre tread is to supply hold on the roads through snow or rain. The winter tyres have bigger tread blocks while summer tyres have smaller ones, this is why they are noisier when you drive through snow.

The groove which is the hollow area or cut of the tyre tread. The groove is the different patterns on the tread. You can find a simple pattern, the v design to a horizontal pattern. The groove is made to channel out water and push it away from under the car. The way the groove is created will affect the way and quality of any winter tyres. As the tread begins to wear, it will affect the groove, as it will begin to become less hollow and plain.

Another feature that you should look for in winter tyre test, is that at both sides of the tyres edge, you will find a small tread, this is the pitch. The usefulness of the pitch is to improve the performance of the tyres by offering greater stability and better steering. You can easily notice the pitch on winter tyres, as it stands to hold and grip any icy road.

Winter Tyre test

Winter tyres have high void ratio. The tyre void ratio is calculated by the open spaces on tyres. A winter tyre with high void ratio will help to speed up the evacuation of any water on the road, as it is related to how much rubber is in contact with the surface of the road.

To prevent tyres from sliding when it drives over water (aquaplanning), the pattern and the depth of tyres is important. On wet or icy roads, winter tyres should be able to get rid of water from the treads easily, in order to prevent sliding of the vehicle which can eventually cause accident. Once the tyres rotate, the treads move water into the pitch and the groove, the water is then pushed out from there, enabling the vehicle to accelerate smoothly without sliding.

Many winter tyres have metal studs that are designed in the tread. The metal studs make it possible for the tyres to give a better grasp on the ice and snow. Even though winter tyres can be very noisy, especially on dry roads, it provides road safety during snow or ice. In some countries, it is mandatory that drivers fix winter tyres on their cars, as the weather may become extreme and therefore a danger.

Special winter tyres that are made for snow and mud are marked with the symbol M+S, to show that they are created for extreme snow conditions. The symbol for snow flakes and mountain is 3PMSF. This symbol indicates that the tyres meet winter tyre test conditions.

How Do You Perform Winter Tyre Test?

There are different properties that you can check to make sure that your winter tyre are the right ones. So how do you perform winter tyre test? The improvement of winter tyres have moved up lately, with high rate of speed and new designs reaching the market.

To find out which winter tyres that will be the ones for your vehicle, you need to check that the winter tyre test satisfies the following winter road conditions:

  • all requirements on wet or icy road, energy usage and noise

  • grip, braking and snow handling

  • excellent snow performance

  • minimal rolling resistance

  • well-balanced driving performance

  • short braking distances and accurate powerful handling on wet roads

  • minor change to weight of loads when driving on snow

  • great safety margins when aquaplaning. Stable cornering, especially on wet roads

  • accurate steering result with excellent feedback on dry and wet roads

  • the price condition for the winter tyre test are generally given a minor consideration
