Just changed 4 pcs Continental CC6 for a Honda City TMO, sized 185/55R16, replacing the original CPC2. Price, was RM190 per pc excluding GST from Weng Heng Bukit Kemuning.
Slightly quieter and slightly more comfy overall, while grip is reasonable for the car. Rolling resistance seems better.
Still early to say as I only did an outstation drive for about 400km with it, but definitely much better than the CC5.

Well, first I didn't want to exceed RM200 per tyre, so XM2 was out.
Then I preferred quietness/comfort so Hankook V2 Concept 2 was out as it's a directional mid-range performance tyre.
In the end, I was planning to either go for Toyo NE03 or Dunlop D05, mainly for price and good reviews. Turanza ER300/370 seemed to be older model, and Ecopia EP200 I heard had low threadwear. Goodyear Excellence is also out as I don't think it's good or quiet.
Anyway, then a friend of mine recommended CC6, so I didn't need to decide between NE03 or D05, haha!
The price was good, and I trusted my friend's recommendations, so that was it.

Those prices seem on the high side for 185/55 R16. Anyway, I've mentioned my decision making process in my earlier post.
No matter how premium the tyre is, you just have to manage your expectations with regards to tyre noise because you will not get total silence or "quiet".
Just "reduced" noise.

from what I know, some stores that have strong online presence will ship out their tyres. You just have to check what is the shipping cost and see if it's cost-effective to do so, as well as receiving 4 tyres from courier, and bringing it over to a tyre shop to install and balance tyres that weren't bought from them.
