Two months ago I noticed a slight humming coming from one of the rear wheels of my 06 Acura TSX. The humming has recently turned into a much louder groan / grinding noise that both annoys and more importantly, concerns me. My first instinct was that one of the tires was going, so I replaced all four tires today with new tires hoping that might fix the problem (it was about time for new tires anyway). Sadly, the groaning noise is still there. It becomes very noticeable once I reach about 50 mph and when coasting, the noise is very strong until it drops below 35 mph.

A few things that I feel should be mentioned are:
- when I originally bought the car it had been used for 1 year. The back right tire did not match the other three which were the originals. I'm not sure what happened, but something caused the owner to replace that tire. (maybe that has something to do with the noise? It is coming from that side...)

Why wouldn't you just take it to the dealer? You're still under warranty.

A couple of things come to mind...
1 - Check rear brake calipers and pads. Is it time to replace the rear brake pads? Because our tsx wears through the rear pads quick! Is the rear caliper stuck?
2 - Check rear disc thickness. If the rear pads are worn down, did it also wear down the rear discs? Is something stuck in between the pad and the disc?
3 - Alignment? When driving, does the car pull to the side when the steering wheel is straight?
4 - Check the wheel? Take the wheel off and check the points where it connects to the car.

also, it could simply be a wheel bearing to change. Since you mention that one tire was different. Maybe the previous owner hit a pothole, squish the bearing and had a flat. A wheel bearing will take time to get bad. The noise will increase with time. At what point you will feel like you are sit in a small airplane.

Tell me about it...my rears are at 3mm (1.6mm is minimum and about 10.6 is full) but my fronts are at 8mm (same standards). The service team figured I'd had the fronts replaced already...

I am, tomorrow morning. I was just trying to figure out what the problem was.
