Summer tyres such as the Michelin Pilot perform there best when temperatures are above 7c as a rule of thumb, but not at temperatures lower than that. Summer tyres have a high tread elasticity and hard compounds, that as the name suggests perform best in warm weather. They provide great handlng. excellent grip and short stopping distances in both dry and wet weather.
By comparison all season (hybrid) tyres such as the Michelin cross climate share aspects of both summer and winter tyres. They are not prone to the same disadvantages as summer tyres below 7c, which is there main benifit over summer tyres. Another disadvantage of all seson tyre, just like a summer tyre is they don’t perform well in icy or snowy conditions. They wear out quicker than a summer tyre due to there rubber compound and don’t perform as well as seasonal tyres or in wet condition’s.
On the other hand a winter tyre will out perform both summer and all season tyres in snow and icy climates
