so why would you think there's a tyre that's perfect for both +30 and -30 degrees?
i dont - youre putting words into my mouth, im thinking of costs, insurance purposes and hassle.
Ive driven in Poland through a harsh winter on summer tyres without too many problems, drive sensibly and you'll be just fine. If you have four wheel drive, youre already well on the way to better traction regardless of winter tyres.
You can have the most powerful engine and the best brakes in the world, but if you're not making good contact with the road then it doesn't mean sh!t.
I also understand that its better to have 8 gig ram than 2 - problem is cost. If its not a legal requirement i dont give a flying fcuk.
