I have driven my cars on
Yokohama aspec 195/65 R14
Yokohama db 2015/65 R14
Yokohama advan db 195/65 R15
Kumho ecsta 225/40 R17
Among all of these yokohama db and advan db has the best grip on wet, and good grip on dry. As far comfort and noise levels are concerned I drove my cvt upto 200, but I didn't feel that the tyre isn't contacting the surface or there is a loud noise of tyres.
Wet surface? Driven like 150km on motorway in rain, but there was no hydroplane. All I can say that they got the best road grip on wet surface.
Tread pattern defines the wet road grip. One who told you should have worn out tyres
