Where I live, I can go with summer tires year round. I did not do much research on the Dunlops, but I did on the RE950's and the final choice was between them and the Firestone SZ50 EP's which I bought. There are customer reviews on tires on the Tire Rack site which can be helpful. The RE950's got mixed reviews in the snow, from good to not good. Read a few pages of these reviews on the tires you are considering before making you choice.
