Help. a load vibrating or humming sound

[chukstel]

Hello all, has anyone experience a high humming sound like whoo.. When the car is moving around 40km and above.

I have a brand new tyre of 275/70 R16 on both front tyres and I started to get this sound. Also the steering vibrates around 80km and I have done wheel balancing and allognment on four tyres in the vehicle.

Question is this associated with the new tyres or there are parts that are faulty? Please help

It could be just the road noise from your new tires that you aren't accustomed to, but I would check the bearings to make sure you don't have another issue. Checking for play in bearings should be well documented here on the forum, but basically you're going to jack it up and check for back and forth play by placing your hands at 9 and 3, then at 12 and 6, then by checking up and down movement in the tire. These are the cursory checks for tie rod ends, wheel bearings, and trunnion bearings, respectively.
