I used Dunlop Winter Sport M3s on my stock 18" wheels for 6 years/seasons...excellent, never any issues in snow, wet and dry and all temps. Didn't feel lacking in ability to have fun when weather was good with them. I went with the 3Ds on my S5 now but only because they come in 19s otherwise the M3 would be my choice although had no issues with the S5 but we had a very mild winter with almost no snow so short season to have a real opinion on the 3Ds.
