"Huming" Noise from Tyre

[Haziqko]

Thanks for all the advise, here's the information,

 

Car : Saab 9-5 (Nov'06)

Tyre : Eagle F1 (approx. 25k km), 235/45R17

Symptom: "woong, woong" noise is heard between 70-90km/h, can hear from inside car w/ window closed, started about ~10k km ago, but more obvious recently

Others : rotate tyre every 10k km. Done 4 wheel alignment and wheel balancing 5k km ago

Changed the front support bearing, front arm bearing, thrust bearing and suspension bump stopper about 34k km ago (before current tyre).

Tyre pressure : 38psi (manufacturer recommended 36psi)

 

 

could be both the tyres and the bearings gone. The tyres are sure noisy when worn out and the bearings could be gone also.

 

tire pressure seemed ok. i pump +4psi on all wheels and find that it becomes a bit noisy too.

Agreed, had the same problem on my ride Fit. Need to check all 4 tires.

Usually its the back wheel bearing. Hope that help

replies here are all just adviced base on your quotes.

so the best is go to your workshop or tyre mech to have physicall inspect on both tyre and test drive it ,An experience

mech should able to solove your problem.

self medication could cost you your LIFE (best consult your doctor but cost your consultation fee )

seld medication does help you to save money but be responsible to yourself.

Bro, time to change your tyres. I'm facing the same problem too. Likely is due to absorber that causes unbalance thread that make the sound:)

I recently changed my tires to Falken Ziex912, there is a constant "humming" sound when the car is moving more than 50km/h. I did not have this issue when I am on previous Federal tires. I got C&C to check my bearings and even the chassis, all are well. I even went do a high speed balancing for the front wheels but the noise is still there. So my conclusion, must be the tires. It seems that Falken tires have this "humming" noise issue with certain cars...

if your tyre(never mentioned the brand) got the humming noise immediately after the changed i tell you you can throw away this tyre.

noise like this is either from tyre or wheel bearing also happen the dented wheel(very rare).

Please dont waste your time or money go and balance /high speed balance/ check absober/spring.

I hear this Falken 912 has high wear rate about 20k, so the next change will be Hankook I did use the old V8RS on my previous ride and the wet grip was "No horse run" especially when I am travelling on NSH.
