I live in coastal Montenegro, which means the winters are mild with loads of rain; the issue is if you drive a little bit north, you encounter snow and ice road conditions. That is why I went for the allseason type of the tyre, because my previous experiences with 'proper' winter tyres has not been great - they would wear down quickly in the mild weather.
Continental AllSeason contact performs well in the wet conditions, which was very important for me (we have epic rain in Montenegro). I also tested it on several occasions while driving though compacted snow in the mountains, it gripped surprisingly well; on several occasions on the ice patches it tended to 'dance' a bit, but no major issues.
The only real drawback is the warm weather performance - since February the weather was sunny and warm, and the tyre does not perform as advertised - it becomes a bit slow and 'mushy' regarding the feedback. The wear is also not great, as it started to have visible damage to the surface. Also worth noting, the tyre picks up little stones everywhere you go - I suspect this was due to the warm weather and the 'stickiness' of the compound; I can only imagine what would happen in the summer temperatures of 40 degrees Celsius.
Just lately I have reverted to my summer tyres (Dunlop Maxx Sport), and the difference is incredible.
This is not all season tyre. I assume you could use them all season long if you live in mild to cold weather, but then why not buying proper winter tyre?

I've finally had chance to use this in snow and they're as good as they are in the dry and the wet. A really well balanced all season tyre, highly recommended. Only thing I've yet to try is really warm running.

Over summer on dry and wet is great tire. In town ride on town-weared roads I get no spinning of weals. Start/stop on during rain also great - Golf MK4 150hp. Now when cold weather is also great behaviour on roat, open road also great, quiet on hi speeds. Dont know how it will be on snow, ice...but I dont expect poor behaviour. Previously I owned Kumho solus vier (all season), It was ok first year - but after 2 years it was so bad I bought 4 years old used winter tires and that was BIG improvement. Kumho on dry town roads was all time watching brakes and peddals - if i want to join trafic fast - i get wheels spining...Terible on wet road, teribble on snow - tires were as plastic! 4Years old 2 dunlop and 2 godyear tires were great for change that winter...until I bought Continental AllSeason - Now I get reliable car on road, reliable behaviour, brake, start. No need to drive EXTRA carefouly. Will see how is with wear over time. I bouht continental over michelin because of wear - in test and reviews I see Conti get more miles, and caracteristics are ok for my wheather conditions. I dont think it would be wrong to select one of top 3 tires on these reviews. Where you drive and how much is important. I dont drive much, no snow more than few days/weaks...some rain. If I would have more snow or winter conditions I would probably go for michelin all season tires!

Initial view - excellent tyres well worth the price. Changed from Continental EcoContact 3 (5mm tread left) to AllSeasonContact. Big improvement in ride quality. Refinement improved at motorway speeds- much quieter over coarse motorway surfaces. Steering precise with better turn in, feels more like a good summer tyre than a winter tyre in this respect. More compliant and settled ride, soaks up bumps, surface changes and mid corner bumps much better. Stable under heavy braking. Higher level of grip in wet weather compared with the previous set of tyres. Not yet used in the snow.

After driving "crossclimate" and "4seasonG" can confirm that this tire combines characteristics of Michelina and Goodyear.
In my car before the all year tires I had a continental summer and a special winter set.
It is not true that it is actually winter.
quite different in the summer than winter tires eg TS-830.
The feel of the steering wheel is better than that of Michelin and Goodyear.
The tire has a great traction on the snow and lateral stance as opposed to the trembling crossclimate.
Goodyear is more comfortable and quiet, the rest is about the same.
Continental, however, keeps the dry road better than goodyear.

So I have to say, as all season tyres go, these are a revelation.

They follow the Michelin CrossClimate Plus tyres in terms of being a bit more summer biased, however, these are more capable in the winter.

They are not as quiet or as comfortable as the Michelin's, nor do they wear as well, however they do excel at providing much better grip in all conditions.

This being said, the great winter grip and tread is excellent. Also, the wide sidewalls do a great job of protecting the alloy rims too.

I genuinely think these are utterly excellent and will be buying them again in the future.

Have just replaced a set of crossclimates for these contis and very impressed so far. Very good feedback, less sidewall roll than the michelins and altogether giving more confidence in cornering speed in both dry and wet. what bit of snow slush and ice driven on still gives positive grip and feedback. very difficult to spin out with 4wd and uprated ecu map.

Initially tested on very wet and slushy country roads and additionally on 5-10 cm compacted snow in the mountains. Tyres appeared to perform as well in these conditions as my full winter tyres (Nokian WR D4). Dry braking performance in the 0-8 degree range seems very good but fast cornering and general dry handling was lacking a little to my summer Pirelli's when the temperatures were nearer 8 degrees. Still sufficient dry handling for all but the most spirited of drives I would say. Early impressions are good, more winter and dry testing needed but the wet performance has been exemplary. No wear yet so too early to give a wear rating.
