Interesting to note a winter tyre stops in a shorter distance in the wet than a summer does in the dry.
My friend is a tyre development engineer based at MIRA for Continental & he said tyre companies spend more on developing winter tyres than summer as the rewards in terms of development are higher, whereas it's such small margins in summer tyres & the knowledge base is deeper that it's all much of muchness.
Many tyre companies recommend that if you do a low annual mileage, that running winter tyres all year round makes more sense than a summer tyre as the loses in the dry are much lower than the gains in winter.
But one area a summer tyre wins hands down is subjective feel, winter tyres do feel a little less positive on turn in & feedback.
