Hi personarian.

Last monday i just change to advan db, what i can say the road noise is significantly reduce. Now the wind noise at the door visor more apparent and also the engine noise.    Thinking to cabut all the visor but afraid the ither noise more apparent.  The road noise is significant reduce start from 80kmh above.

Before this my car got whooong noise, i tought that because of wheel bearing, but after change to new tyre the whooong noise are gone. I change tyre at 48k km eventhough 2 of my tyre still got 30% thread, cannot stand with the uneven thread already got vibration when doing 100kmh above. Now the vibration problem also has been solve.

For the handling and traction of course much better than stock silverstone kruizer ns500. This is the first time im using premium tyre so no comparison with my previous tyre. But i still get scretching sound when cornering hard with advan db, donno if it good or not. But i feel the sidewall is slightly harder compare to my old tyre. But the comfort felt better maybe the new thread still thick. In conclusion this tyre are better in all aspect. Not much comment on this segment. But of course cannot compare silverstone low end tyre with yokohama high end tyre lol 

both are different thing. but it comes together.
