SP WINTER SPORT 4D

I have driven these in Ontario winters for the past 5 years very capable tire. The road noise, the tires growls a bit, but to be expected from a winter tread. I have had them installed on Mercedes GLA since new and replaced them this season. My tire installer suggested I could get one more season from my old Dunlops. Personal philosophy, the least expensive thing on our cars is our tires and brakes, why gamble. Great tires did definitely purchase again.

Excellent on dry road, bit on icy or wet dissaster...last week i had 2 time understeer with normalna speed. Road was wet...I'm a little bit disapointed.

I got these tires as a package with the wheel. They are Mercedes OEM tyre (MO) and unfortunately I got it with S Class W222 size, so for my W213 E350 petrol hybrid it was tight on the front part. There was almost no clearance with the arm. So word of advice, please get the 45 ratio if you want to put it on a W213. The wheel set is not staggered setup like the original AMG wheels from the car so all tires have same size.
I have driven with these tires for around 3500 kilometres. One part of it was a journey from south Finland to Lapland at the northern part for ski holiday. I wasn't sure that the tires can keep up with Finnish winter because the temperature, snow and ice is really bad here and these tires are central European winter tires.
So when I installed the tires it was already minus 3 to 7 Celsius on average daily, plus snow almost everyday. The road was slippery and yes during heavy snow it is not recommended to drive with this kind of tires. I have missed many red lights because of longer braking distance during snowfall. The tires also struggled to get a grip on snowy street especially when going around the roundabout or in a smaller street where the snow plough truck doesn't go there. When there is black ice on the intersection of course you can feel that the car is losing grip but it immediately gain it when the tires hit the road again.
The feedback and handling during cold temperature on dry road is really good, I can feel where the car is going and I can tell the car to the direction that I want.
Nevertheless during my 2500 kilometres trip to Lapland where the temperature reach -17 to -20 there and heavy snowfall on most cities, the tires performed really good. On dry road once in a while I hit 120-130 kmh in a safe empty stretch, I feel that the tires is gripping really well. There was one part during the journey where there was a freezing rain, the ground was wet and all the rain drop becomes ice that blocked your windshield, the tires were holding really good. I never felt that the car was about to skid or do something unpredictable. When there were some heavy rainfall the grip is still there and I can easily handle the car.
For aquaplanning experience, there has been some times that the car lost the grip but still manageable even in higher speed (around 80-100 kmh). Also the noise level in the cabin it feels a bit high for my liking. I don't know if it is because the directional pattern of the tread.
Overall this tyre is good and depending on the price, you can consider also to put on your car if you don't have harsh winter like in Finland.

In short I am really impressed by these tyres and I can easily recommend them, although I don't have a direct comparison with similar winter runflat tyres. I chose between these and Pirelli Winter Sottozero 3, and ended up with the Dunlops. I would definitely buy them again.
On dry roads they behave really well, with good comfort and lower noise than my summer Continetals 18 inch (staggered 275 / 245). Only thing is that you feel the extra sidewall in corners at higher speeds. No complaints on wet roads and very good traction in snow (xDrive helps as well). Only on ice you start to fell their limits but overall I found this to be an excellent and versatile winter tyre. Cannot say exactly how long they will last, but after 4000 km there is minimal wear.

Have spent two full winters living in the mountains on the Italian Austrian border, driving between ski resorts on steep twisting mountain roads and motorways that were sometimes covered in deep snow and ice, as well as days when it was heavy rain or even in springtime 30 degrees hot......and the Wintersport 4D's never let me down. On more than one occasion I got out where others also in 4x4's were having to fit snowchains. They always felt assured. They have had 15000 miles of use and still have loads of tread left. I use Michelin Primacy 3 in the summer but actually prefer the Wintersport 4D for feel and handling, they are certainly better off road too. I was recommended this tyre by someone that had used them and can only echo that recommendation. The drive to our house had a steep drive which often became sheet ice that you could not walk on, but with these tyres on the car just drove out like you were on tarmac. Will definitely buy them again.
