I got my tired changed and then suddenly when i'm driving i hear a loud raoring/humming type noise coming from the tires I think. Coming from the back and the front. I thought it was because of the new tires, but it's been a month now and it's not going away.

Any ideas other than bearings? Maybe bad tires? I read online it could be bearings, but can it just break from getting your tires changed?

It's hankook 727's i think 15inches.

Also the noise is same when i drive on different surfaces as well.

 

Wheel bearings could be the problem. However, if you are saying it is a constant noise (no change in sound when cornering a certain way for example) then that's not as likely.

Next I would say check out the tires, but I'm fairly sure those were actually supposed to be fairly quiet given their tread pattern... they definitely shouldn't be loud given that they are new.

The sound started just after you got the tires? There could be some other causes but perhaps a more accurate description (if possible) would help diagnose this?

 

Yea i can hear at around 20mph and up. It seems to be a constant noise, one frequency level. But as you speed up, it sounds different. I guess more of a buzzing than compared with when going 20 mph.

Doing anything above 20mph will get the noise. Cornering, switching lanes etc.

Yea, totally brand new, bought online. Is it possible that, the bolt is too tight or the balancing of the wheel is messed up? I noticed it after putting it on at a shop and driving home. I read that some brand new tires are noiser, so I didnt' worry, but now I am. The noise is driving me nuts, and the safety factor is making me worry.

 

I don't blame you for being a bit worried. Usually if they balance was off, you would feel it. I don't know who put them on your wheels but do you know if they balanced them? Or if they did, do they have a good reputation?

The 20mph on up thing is definitely in bad bearing territory... although usually you can tell what bearings are bad depending on how you corner. I suppose they could all be bad but I obviously cannot say for certain as:

1) I'm not there to look.
2) I have no idea EXACTLY what the noises are like.

Guess the only way to know for sure is the get in there yourself or have a mechanic look at them.

 

How much would it cost to get fix? I see bearings for 30 bucks each, but hubs are like 80 bucks each? Would I need to replace hubs as well?

 

usually with new tires there should be noise or is it like skateboarding noise?

 

I don't think so. It just sounds like humming/roaring.

When I turn and make sharp noises, it still seems to be there. Also I noticed it's actually happening at around 15 mph. Also just got them rotated, and still making the same noises...except it seems to be quieter at around 50 mph's. Like quieter than driving at around 20mph's. Kinda weird.
