First, let’s define what we mean by all-season tires? If you think that all-season tires – tires which are equally good for winter and for summer, you’re wrong. All-season tires – a tire which characteristics are satisfactory throughout the year. What determines the performance of the tire? The height of the tread, and tread rubber compound of which the tire is made.
Winter tires have a high protector adapted for crushing the snow, followed by purification of the tread. Tread winter tires consists of a lamella (dissected into several slats) blocks. Rubber material of the winter tire remains flexible in the cold.
Summer tires have lower tread. The main thing for the summer tires – to ensure reliable traction on asphalt. This is achieved by applying a specific tire tread width and depth of the grooves separating the tread blocks which is small. There are also rain modification summer tires. Their protector is designed so that the water that gets into the grooves of the tire tread, flowed freely from there.
Rainwater tire often has a longitudinal groove encircling the entire surface of the tire tread and recesses formed at an angle, allowing the water to drop from the tire side. There is special marking on rain tires indicate the direction of rotation of the tire at which the water discharge. If you change the place of the left and right tire, instead of dumping the water it will drained. Regarding the composition of the rubber, the summer tires are made of materials that allow the tire is not “float” at an elevated temperature. The all-weather tire is an attempt to find a compromise between the performance of summer and winter tires.
In fact, all-season tires – is adapted to the winter road tires. The tread of season tires is lower than the winter tread but the tread blocks, as well as in winter, are separated from each other and cut into lamellae. Notes that all-season tires are designed for countries with more lenient climate than Canada and Northern states , it is partly true. In severe frosts all-season tire is not as elastic as winter.
Most manufacturers recommend this type of rubber for use in the natural zones, where the average winter temperature is around 0 °C.
- All-season tires are cheaper than winter and its prices comparable with the summer.
- When changing seasons, no need to change a set of tires.
- In winter, the weather is different, and all-season tires work well on snow, good handling on the asphalt and, unlike the majority of winter tires, doesn’t produce any noise when driving.
- In the fall and spring you do not have to rack their brains over the question: is it time to change tires?
- All-season tires lose winter ones on ice and packed snow.
- Seasonal tires wear six months, and all-season all year round.
- All-season tires are resilient enough during severe frosts in winter and too flexible when summer temperatures.
- All-season tires maintains its quality up to -7 degrees centigrade. Then it’s loses its elasticity.
It should be remembered that all-season tire – not for racing and off-road. Accordingly, it is necessary to focus on your driving style and road conditions, which you have to face. Think about whether you fit all season tires?
Of course, we know that life teaches man to compromise, however, the case is an exception most experts urge not to accept all-season tires when living in a harsh winter conditions.
At the same time we must remember that all-season tires are more expensive because of the complexity of manufacture.
