This is the tyre's resonance frequency that caused this noise, my car also similar, just the speed range not as wide as yours.
Nothing to do with the alignment and balancing of the car. You can play around the tyre pressure to reduce the speed range of this noise.
6UE5T you have this issue on the myvi and swift?

tq for ur resonse. this is my 5th change..as far as i remember never had this issue after changing new set previosly. perhaps this is unique to this tyre. this is my first time using hankook k120. will the resonance frequency faded after tyre break in. nway i will not noticed it if i really focus on detecting it/ when turn on radio.. haha..

Hmm I don't notice any such noise from my son's Swift or my wife's Livina (not myvi). The Swift is quite loud though coz of the sport exhaust. The Livina is just normal quiet but the tires were used that I got together with the used rims.
I did when on 003.
90-100.
120-130.
Very very obvious wung wung wung sound. Only sound, no other abnormal findings.
Change to PS3, ranged at 90-95.
So yea, its the thread oattern etc etc.
