IMO: Conti dws arent "good all seasons" they are good for a UHP in the snow.
Conti lx25 are good all-season tires.
In most winter weather situations, winter tires provide better predictable handling.
It's been a long time since I've used conti. The dws was the last ones I've used but for 2014, they weren't too bad compared to the Michelin Alpine PA3 that I had at the time. My sister has the PureContacts and those were good in the snow and the reason why I decided to try out the TrueContactTours now.
I still use blizzaks for the winter but I'm willing to try out these TCTs in the snow.
