already change all my tyres to 195/55R/15 CC5 for the price of rm215, as i heard CC5 is the noise killer. trade my M5 for the price of rm150-all tyre, distance 38000km. now the soundproof can be maximize but the engine sound still can be heard. engine is ok, can tolerate rather than the sound of the road surface which is annoying as @*#*. i guess i have to put back the original filter, the sound is noiser if with out it, but will sacrifice pick-up if do~

should i do align if change tires? i dunno about this. too long, forgotten already procedure if change tires. however, i'm getting to like my car even more now.

wow .. where u trade in? interested man 

Thinking of a vw....

how much the petrol consume per km?

Finally I change to Continental CC5 195/55/R15 4pcs straight 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

My XM2 starts to become noisy already.

Bro,

so u total pay RM215x4 then minus RM150 = RM710 right??

yes, total all 4 is 710...emmm actually is 700. i keep on bargaining. sorry for my confuse sentences.
the tires is good thou, good for alza. already try at nkve at 140-150, can still hear the sound but not xtreme sound like m5. up your radio until volume 11, it should be good. need to remind again we are dealing with a 55k mpv.

so fast...?

you went drifting all these while...?   

radio volume 11 at 140-150kph on CC5...?   

I thought you auto-foamed and soundproofed your car....

yes, still not done with the roof, floor, firewall and engine. i read somewhere in the internet, that you have to do a compete/extreme sound proof otherwise and average work will get an average result. well, I'm not rich, need to do section by section. but i'm glad with the increase result. But i always remind myself, it will not became bmw, porshe or ferrari kind of comfort. comfort as in like a 100k+++ car is fine enough. 

the auto foam is good by the way, handling and cornering give more satisfaction unlike before.

complete sound insulation at one short is no fun... have to experience it step by step... guess I am too poisoned by KL Auto... though not very kind to my wallet since step by step treatment is more expensive compared to single complete treatment, then again it gives me the chance to save up and treat it bit by bit...
this one i agree... have you also autofoam the side sills...? me gatal now seeing good reviews from a Sonata driver, wonder if it can reduce the harshness and vibration further on my Alza...

hi guys,
my alza rear boot handle is loose/broken alrdy, rear boot cannot open leh..!
