Hello, yesterday was with my friend regarding winter tyres for my new used XC70. The car currently has all-year tires on the rims and my friend thinks that the car would drive with these best. Since I learned then that one should have winter tyres and in summer summer tyres on it, I am a bit confused. Not, the all-year tires are bad, but I think that one did not invented summer or winter tires for nothing. What do you mean? Thank you for your answers Greeting Volvokalla
