Suck.
But then I am conflicted when I say this because I stole these from Sabio for a measly 200 bux. A fackin steal for 205/50/17s with 3K on 'em. There was a nail right on the edge of one of them (as Sabio had disclosed), but it was deemed repairable by Tires3000 (but get this... the guy told me he put the repaired tire on the rears... just in case - LOL!).
Traction is not very good in slush and ice. Acceptable in powdery snow I think. But overall, my traction control light is continously on. Then again, I went one size narrower for the snows as 225/45/17 is the stock size for my car.
These $hitty tires may be good for lame a$$ torque-less rice-mobiles like the Mazda3, but for fine pieces of German engineering, they barely cut the cake.
On my Mazda6 I had Dunlop M3s and those were awesome. Felt ultra-confident in those.
Overall, in terms of VALUE, the Vikings probably rank right up there (and I believe the original reviews bore that out), but I'm not a fan. I would not buy these again... unless I could buy them for $200 for a set of four again... LOL.
