So they've been on for a week and so far so good. No heavy snow just yet, but doing well in freezing temps and drizzle. One thing really stands out and that is how much nicer the car feels without the runflat tires I will seriously consider selling the current runflats and going with a normal performance summer tire. The ride feels better and there is less road noise. Anyhow, I'll report back on these Minervas once we got some serious snow on the ground.
