Started hearing this loud humming sound from my tires first assumed my tires was unbalanced then I recognized it was my wheel bearings in the rear, I hope this video helps you identify your problem and hopefully you go fix it!
Interesting because I have lots of vibrations around 80mph in my 99 GSR and I was thinking maybe it's my wheel bearings but I never thought about getting the tires balanced and checked.
i replace the wheel bearing and the sound sane sound is still there. some said it could be the tires and might need wheel alignment. ill go to the tire shop tomorrow or get a wheel alignment first. ill let yall know what could be the real problem.
