Updates after driving 300km:
2. Tire roar is definitely on the louder side, this is even after I readjusted the tire pressure.
3. Suspension is on the stiff side, but not too intruding for me la
2) My car came with Premium Contact 6. The noise baffled me at first, those are rather premium touring/UHP blend tires. The tipping point was 2000km, they become nice and comfy after some rather long break-in period. HR-V come with what tires? Give it some time and continue to observe.
3) Suspension for road use, there are 2 important distinct signatures it needs to handle for regular drive. High speed low amplitude and low speed high amplitude.
The speed here is not the vehicle speed, but rather the speed of the shock absorber movements.
Low speed high amplitude is like during cornering, the vehicle has gradual weight transfer that compress the outer wheels suspension and extend the inner wheels suspension.
High speed low amplitude is like gravel road, bad pavement, brick roads that give constant fast vibration but relatively small movement to suspensions.
To me, a good and balance suspension for road use is stiff on low speed, which provide good support during cornering, and yet soft on the high speed movement to absorb the vibration.
Such that the car is still pleasant on the bad pavement, but the driver can clearly feel the road reflector etc, and over road undulation change the car settle in just 1 swing.
I'm not a fans of magic carpet ride, so if you think it absorb the rapid vibration well, then it is good in my world.
Of course if driven fast over a pothole fast, that become high speed high amplitude, no road car suspension can handle that.
I'm a little bit tempted to upgrade to Ohlins DFV. The kit for my car is 80% stiffer then stock, but it has separate bypass valve for high speed movement that allow the shock to behave like "soft" in rapid vibration. It is a hefty cost for sure.
