My experience using this tyre (1.5 years ~ 30k km)
Grip : Decent for daily drive n heavy rain.
Noise : its really quiet when new. Once worn down to 60% or so, started to become noisy
I would says its suitable for a daily drive car and not so aggresive driving.

It's been 6 months since I've changed mine.
For the most part, dry and wet grip has improved lots.
In the sound department, consider ok. I'm not as anal since I always drive with music blaring into my ears.
Sidewall is rather bulbous and soft. But it is not as soft as Conti CC6s. If quietness &  plush ride is your main concern, CC6 won. But for wet and dry, my money goes to ATM2.
A nitpick for me is the sidewall design and bulbous look. Other than that no concerns. My previous tyre will activate TCS whenever I sped off a junction. Worst still, wet braking on CC5s.

I usually do 31 front, 30 back for 15"

Weird i use ATM2 for 4 tires. No isu with aquaplanning. Spd 100-110kmh during rain. Maybe the tires still new about 2mths.
