Nexe4n Tyres

Yes because it isn’t just about snow or ice, it is about better cold and wet weather performance (better grip, shorter braking distances, resistance to aquaplaning to name but 3) and therefore safety for you and other road users. 

A number of years ago - I needed new tyres on my E Class Mercedes saloon and 4 tyres from Michelin (I think) or was it Dunlop - not sure) were very expensive.  My dealer (not a Mercedes agent) suggested Nexen and with a good price we fitted them.  The fuel economy dropped a little but otherwise one could not tell the difference.  I would have no hesitation in re-shooing with this brand.  Hope this helps.

Agree there is probably nothing wrong with Nexen tyres however it is a bit disingenuous of the dealer to offer a summer tyre in response to a request for all season tyres! I suspect wear rate on Nexen isn’t as good as the premium brands. 

Had 2 lots of Nexen on 2 Sorentos. First ones perished in the tread before 25k miles.  Replaced with Kuhno and car towed better due to stiffer tyre walls. Nexen came as original on new 2018 Sorento. I was disappointed. At 35k fronts were at 3mm and rears at 4 but showing signs of perishing.  Son is manager of a national garage chain and has fitted Goodyear SUV all round.  He did offer a cheaper brand but recommended the Goodyear.  I won't describe his face when I mentioned Nexen.  So far found raid noise is reduced but so is fuel consumption.  He did warn me that the Goodyear are stickier, rated A in rain.
