Had the dunlop winter sport 4d last year and were great! Changed car so changed tires, the car was on pirelli p6000 summer tires, put the winter sport 5 on and the car is tranformed, better ride, more grip and is so much better to drive although there is slightly less feedback but probably due to size difference. Driven on black ice/ frosty roads and was like tarmac, no slipping or spinning. Heavy water and floods didn't feel any aqua planing unlike the pirellis. Basically an all round excellent tire and if they're like the predecessor they will be excellent in snow!

Bought these tire brand new, there wasn't much out there interms of reviews etc for these when I bought them (Nov 2015).

Tires them selves are very good looking. Driving on them in both dry and wet seems very good. I have excellent confidence in the tires in all conditions. So far though I have not had a chance to try them in their element of very cold weather, so snow and ice performance I cannot comment on. That being said I'm glad I have bought them after some scary moments on summer tires in my F30 last year in snow/ice I feel much safer going into winter on these tires.
