Recently I have been getting a loud hum from my tires, so I rotated and balanced them. When I balanced them, they said the only tire out of balance was my rear passenger. Not quite sure why that one wheel would be out of balance. Possibly wheel bearing going?? Not hearing a grinding sound or anything just a humming sound starting at 40 mph. I have Conti. DWS for not even a year yet and only go to work and back. I have read in numerous threads that they are one of the quietest set of tires to purchase, which is why I am concerned. Just wondering if anyone has an idea of what it could be or if any one could of had the same issue. Thanks in advanced.

I had the same issue but only over 65mph. Turned out to be the front right wheel bearing.

does the noise get progressively louder with the speed?

I had no issues with DWS in the past, Im betting as the poster above me stated its a wheel bearing wearing out.

Does it increase with speed, and does it become louder on hard turns?

It's only between 55-65. I know i said 40 but its really noticeable at 55. Doesn't get worse when I turn or anything and once I hit around 70 it's gone. It isn't a grinding noise or scraping just a hum. I am taking for a trip in a few days hope it's ok.

If its a set speed could be balance, round, or something in the driveline resonating

It almost seems to be varying with different speeds now. So over 60 its almost gone and now just at 50 to 55 it's there but not as bad. Not a clue of what it could be, but now that it is quieter I almost want to say it is my tires. I guess time will tell. Could it be cause I just rotated them? Sorry for all the questions I usually am pretty good about cars, but this has me stumped. More opinions are very welcome. Also thanks for the prior posts.

OP I had the same issue with my dws tires. I had them on my car for about 10k miles and I progressively heard a humming sound more and more. I thought it was a wheel bearing or a suspension related problem but after multiple checks, nothing.

Finally I looked at the tires closely and you could see pretty significant feathering. (Test it by running your hands in the opposite direction of the tire rotation and see if there are "cliffs".)

I notified tire rack and they gave me a full refund towards a set of PSS and I have not had a sound since. I know the dsws were said to be very quiet but I guess I just had a bad set. The car also felt a little squirmish at certain speeds while on its final legs.

I will have to check that out. I called Tire Rack today and they said that I will have to bring it to a Rep. so they can look at them. I will do that and see what happens. I have to go on a trip tomorrow on them so I hope it works out. I don't get the feeling that they are squirmish yet. Thanks for the advise that helped a lot. Did your humming go away after you slowed down?

I'm not sure if that's the issue or not but the "cliffs" he's speaking of is called tire "cupping". Looks like this:

Wow, mine looked nowhere that severe, that is insane.

Very odd, my tires now are wearing properly with no odd patterns.

My car is doing the EXACT same thing. I also have DWS tires on 162's. I did have the rear bearing replaced 2 years ago (at 70k miles) and that was a constant humming that was quite loud. I have had the tires replaced and road force balanced several times. It does seem more noticeable when the car is cold from sitting in the garage all night. I was toying with the idea that the drive shaft was slightly out of balance. Just spit balling.

Ok thanks for the picture I will look at them tomorrow for exactly that. I doubt they are that bad like pits said but if there is any sort of cupping or uneven wear I may be able to see it now that I can see exactly where and what it looks like.

@denny I am glad some one has my set up and is having the same issue. I don't feel like I'm alone anymore. I did sort of notice that my car did sit a few days on base while I was on duty and this afternoon it was bad. Now after that I drove it and either I got used to it again or it wasn't as bad. I guess on my trip tomorrow night I will really see since I'm driving about 6 hours. I just will have to have the music up lol. I don't feel any wobble or vibration so I'm guessing its still safe. Do you have any spacers or anything else done to your car? Let me know if you hear or find out anymore details.

Bone stock sport suspension with factory sized DWS tires. I was thinking either drive shaft, the drive shaft center support bearing, or maybe a front wheel bearing. I don't think it is the wheels/tires. Front wheel bearings I can do myself, drive shaft or support might be a little much to do myself.

I think if it was the drive shaft then we would be getting more vibration then anything. It could be the front bearing but then it would be making noise as you turn at slow speeds too, which I'm not getting. I'm still questioning the tires, do you hear it from a specific area or from the whole car?

Ok so I took my car to a shop and they put it up on a lift and ran it and found that the rear left wheel bearing is humming really loud. So I will replace that and see if it helps, I'm sure it will.

Hmmm, I guess it could be my other rear wheel bearing that hasn't been replaced yet.

Yeah I would check it out, they ran my car up on the lift and listened to the bearings. That's the best way to find a bad bearing. Our bearings sometimes won't oscillate noise if the bearing is really bad. Which is why they aren't as easy to identify. I changed my diff fluid also and it feels very smooth now, well besides the bad bearing, which will be replaced Wednesday.
