Pattern?

Looks like a pattern emerging here. Everyone with premium winters seems to be happy, everyone with anything less, ho hum

Bear in mind there's also the psychological factor. When its really cold you take it easy and your winters feel grippy. When its warm and dry you push harder and find less grip.

Also, its unlikely that a winter tyre will grip less when its warm. Logically, any tyre is going to grip better when is compound is warm and soft. The problem with summer tyres is that below 7 degrees, the compound becomes hard and 'glassy', like a cold F1 tyre. The doesn't happen in reverse, so winters don't need freezing temperatures to perform well, but will simply wear faster when its warm....(a) because you're driving faster and (b)because the tyres are warmer and the compound therefore softer.

I think the bottom is line is that summer or winter, 300 ponies and a chassis with high mechanical grip needs a premium tyre.
