These tires perform extremely good for an all season tire. They feel more like a high performance summer tire than an all season. I had Kumho 4X before these and I sold them after 6 months because they felt so vague that I no longer enjoyed driving my car. These Dunlops transformed the car back to its glorious self. They have very good and linear response to steering inputs and feel very composed in the way they go down the road.
The Dunlops have very good dry and wet traction. Maybe a little less ultimate grip than the Kumho 4X, but more than enough for road driving. They are also reasonably good on snow and ice. Compared to Kumhos similar traction, but a little less cornering grip in winter conditions. They also have good comfort and noise levels, especially when you consider how responsive they are.
I would highly recommend these tires to anyone that needs some winter capability without sacrificing driving pleasure in the other 3 seasons. I will definitely buy another set of Dunlop SP Sport Signatures when it is time to replace them.
