Amount of vibrations at high speeds

Hello Everyone,

I have a question: how much vibration do you have around 115-125 kmh (70-80 mph)?

I had a terrible shaking previously but after balancing the wheels 3 times, it is now much better. It is good enough that on most roads I don't feel additional vibrations at this speed compared to lower speeds. But on an exceptionally good road (newly built highway) I still feel additional vibrations, though a very small amount.

My question: is this normal? I had a gas car before this where a little bit of vibration is always present so I'm convinced that in that car I wouldn't even feel this. But in the Ioniq 5, what level of vibration is normal? Until 90 kmh it is totally smooth. Totally (on the said perfect road).
