For 9 months, had Enkei wheels w/ Ecsta 4XII tires (245/50 - 18). Rotated after 800 miles and recently after another 7500 miles. These wheels/tires have seen cold, warm and hot weather and rain. Car is garage kept. After the recent rotation, I noticed a strange humming noise that starts at around 45 MPH and persists 'til about 60/65 MPH. After that, I don't hear it anymore but not sure if that's b/c of all the cabin noise or if it's really not there. Thought it must be the tires, so I threw my OEM wheels w/ DWS-06 (OEM size) back on for a few days and noise was still there at same speeds. It's just a low to mid level hum; no vibration or rumbling and the car doesn't handle any differently and feels stable.
Both sets of wheels/tires driven on same routes and same speeds (for the most part). Nearest dealership is 25 miles away so before I drive all way down there, you think it's a bad hub/bearing? Thoughts please? Any advice is appreciated.

 

could be a wheel bearing!!
jack up the truck and give the wheel a little wiggle back and forth, it shouldnt have play

 

Reviving an old thread here... any idea what the noise was from? My wife's RDX has the same issue on the driver's side (from what i can tell) at the same speeds. I just had all of the OEM wheels re-balanced and rotated. The tire tread has about 9 months left. The noise persisted. I do not notice any play with her front end wheels, so I don't want to replace the wheel bearing if it's not needed. It very well could be shot though. It's hard to tell, unfortunately.

I should also mention that I swung on by a local Honda dealership 3 months ago and had them check the wheel bearing as well. They said it looked fine.

 

I have a humming noise that did not change after replacing tires. Seems like it is coming from the right rear. Could be the wheel bearing. I need rear brakes also and taking it to the dealer to let them confirm and replace both. We are going out of state on vacation and I wont have time to DIY.

 

 

Sounds like a wheel bearing. Had that issue on my TSX. Does it get louder when you drive faster?

 

Had the same issue, recently replaced my tires and thought that the issue was tire related. Took my 2013 TL FWD (165k) into my local Honda Dealer and they thought it might be tire related (in other words, they couldn't find anything). Took the car back to the tire shop and they offered to replace them with a new set even though they didn't see any issues with the tires;I really think it is not tire related and perhaps a wheel bearing(s). Sound is constant above 25 mph and is louder in the cabin than with windows down. No change when car is slipped into Neutral and coasted to a stop until the speed drops below 25 mph so i don't think it is related to the trans or drive train. Does anybody have any thoughts? Any idea how much it would be to replace a (the) wheel bearings? Any additional damage to be done by driving on a failed wheel bearing? Nearest Acura dealer is +3 hours away so not convenient to bring the car in for service.

 

 

Thanks, it is a FWD TL.
I pulled the rotor and it is definitely the wheel bearing so i ordered an Acura wheel bearing and hub assembly and will be installing this weekend. I am hoping that this resolves the issue.

 

IMO: In my experience, generally, a bad axle will not make a humming type noise.

 

My issue was bad bearing; replacement confirmed that as no more noise post-repair.
