I just went with Conti DWS on 20s. Happy so far but have not had them in snow yet

 

As long as you don't need bleeding edge handling - the Conti DWS is hard to beat. Comfortable riding, long lasting, not an awful price - and a good warranty.

 

I continue to have nothing but the praise for the Yokohama Parada Spec X. They are the Poor Man's Conti DWS, but at half the price. I like them so much I also put them on my wife's GL450. In Houston driving - - hot and occasionally very wet, they do fantastic - - I've not tried them in the snow, although they are theoretically spec'd for mild snow use. Quiet and smooth up to very high speeds. They do not come with a mileage warranty, if you care - - it didn't matter to me at that price. In the CTT, which sees hard spirited driving, they'll get 20k miles. My wifes GL450 has 25k miles on a set and they're just over half worn. Hope that helps.
