The all-season tyre features several solid ‘tread blocks’. These are classically arranged in a chevron-like pattern. The tread depth is not too shallow like in summer tyres or deep as in winter tyres .
The tyre compound is slightly harder, especially when you compare all-season vs winter tyres. This is how these tyres don’t wear as quickly – the all-season tyre has a longer tread life due to its harder compound. But its compound is not as hard as that of a summer tyre. And in turn, the tread life is shorter when compared to that of a summer tyre.
All-season tyres can carry one to two markings that indicate good winter performance: One is the M+S (Mud + Snow) marking, which indicates that it performs well on both surfaces. However, it is not certified. That is the case with the second marking, the Alpine symbol (3PMSF – “3 Peak Mountain Snow Flake”). This is why from October 2024 onwards, only winter and all-season tyres with this symbol are permitted for use in the winter months.
