All-season tyres combine the characteristics of a summer tyre with those of a Winter tyre. The resulting compromises have a direct effect on the driving characteristics, so that all-season tyres are not suitable for all regions. In addition, drivers have to assess how often within a year is the car is driven and how sensible a tire change twice a year would be.
There are different ways to combine the different profile designs and characteristics of Winter- and summer tyres.
Also, the tyres are characterized by a special rubber compound for the hot and dry months of the year, in order to achieve little rolling resistance, but still to achieve maximum grip. In contrast, Winter tyres should have a strong grip especially on snow, wet and ice, which is why they have very deep grooves, numerous edges and corners as well as lamellas intertwined with snow and mud.
Therefore some manufacturers choose the exact middle path by dividing the profile into two parts, one side for the cold and the other for the warm months. Therefore, the tyre can only claim half of its qualities, but this does not mean that all-season tyres are less secure or reliable.
They offer very good handling characteristics especially during the transitional seasons and can almost keep up with the characteristics of the Winter tyres in some situations. In summer, the disadvantage of the soft rubber mixture is the increased wear and also the higher fuel consumption.
There are, however, also All-season tyres in which there is no division, but the specific properties in the profile design are combined. The risk of aquaplaning is as low as in the case of the other good quality All-weather tyres, as they also have grooves which serve the purpose of guiding the water quickly and confidently from the tyre.
The all-season tyres must, of course, meet the demands and standards of the Winter tyres to be used in the UK.
Furthermore, many tyres carry the snowflake symbol, which is awarded by the independent US agency NHTSA. These All-season tyres must pass a test and meet safety-relevant criteria. Tyres equipped with this symbol promise much better performance than All-season tyres with only the S + M symbol.
For an all-weather tyre to be worthwhile, only those drivers doing very low mileage should use one. If a set of Summer tyres and a set of Winter tyres would last you for six years, All-season tyres would be just right.
In general, All-season tyres are a safe alternative to Summer- and Winter tires.
In the summer, they often lose some of their properties, but they do not affect safety.
Thus, all-weather tyres have slightly less grip on dry road surfaces, and also require more range when braking compared to the Summer tyres.
Even if All-season tyres can be more convincing in winter, they are less suitable for residents of the Highlands.
For the lowland, on the other hand, the winter requirements for those drivers, doing only low mileage are sufficient.
If you are driving a lot and the whole year round, you should consider whether having two sets of tyres (summer and winter tyres) might be a better option though...
