All round best tire for 185/55/16? Don't mind the cost.
Good tire of this size is so limited. 

PS4 for me last 40k km max. That is with proper alignment/ rotation done every 10k km. But performance/grip on wet, it best for me. Always felt it can cope with wet heavy rain, hence repeated few times already. Once current tyre finished, will try Continental MC7 since many said good already, even though I had worst feedback for UC6 on wet (tyre given when bought the car)
