Got my winter wheels today
1. tires are Nokian WR tires with N0 certification. Since they have been optimized for snow and braking on slippery surfaces, they have the V speed index only (up to 240 kph).
Some Nokian WR tires are approved up to 270 kph.
2. they don't seem too noisy but ride comfort is slightly worse, especially with PASM sport setting activated.
Also the steering feel is more "direct" and sensitive.
3. the OEM winter wheels look good, you don't really see the missing 1 cm width on the rear (295s instead of 305s). The offset seems to be different on the rear rims, maybe this is the reason, I haven't checked on it yet.
4. the Nokian WR N0 feels pretty good in curves but since the tires are brandnew, I didn't try them at the limit. They make however a pretty good impression to me, temperature outside was around 8*C today, so it wasn't perfect for winter tires but still...not bad, they seem to keep the oversteer tendency of the summer tires, so they seem pretty sporty to me.
More information to come over the next few weeks, especially snow performance is very interesting to me.
I'll post some pictures this weekend.
And yes, the Nokian WR N0 is a REAL winter tire, not just a M&S tire.
