Finally I change to Continental CC5 195/55/R15 4pcsstraight this morning because out of the original tyre (Synergy M5) 2 pcs were "bengkak" which will blow anytime and another 1pcs was hitted with screw. My car mileage is about 34k as now, the tyres tread were about 50% left.

Review of CC5 (compare with Synergy M5)

Noise
- It is a very big improvement.
- On highway, the music sound (USB) can still be heard even the volume is 5 at the speed of 110kph. The music slowly unhearable after 120kph, mainly covered by the wind sound of side mirror and engine noise.
- In town driving, the sound impact from uneven roads/bumps is greatly reduced, no more "batu" feeling.
- No more tyre rubber sound in shopping complex parking.
- When the car is not moving, no visible tyre noise when turning steering.
- Now engine noise is the most visible sound.
- On the other hand, steering rack vibrate still persist.

Performance
- Pickup not as good as Synergy M5 but very close, due to size 195/55/R15. (I don't mind for the sake of comfort )
- On dry road, suprisingly it is not as grippy as Synery M5 when speeding above 130kph, maybe it is still new. Keep in view.
- Haven't really tested cornering, but sidewall seems softer, may not as zippy as Synergy M5. Keep in view.
- Haven't tested wet performance, it is not raining today
- On the other hand, speedo meter change to slightly slower by 5-10kph (means actual speed faster).

Summary
- It is well worth if what you want is a more comfort drive
