Lately I've been noticing a low "howl" when driving my Kizashi at low speeds. Although it sounds like noisy tires, the Continental ExtremeContact DWS tires I have on the car only have about 8,000 miles on them (I rotated them at 6,000 miles). I have to say it's pretty noticeable at low speeds...not so much on the highway. I find it hard to believe that the tires could be getting noisy with so few miles so what else could it be? The car only has 20,000 miles on it but is there a chance it could be a wheel bearing? I've had failed wheel bearings on other vehicles and in the early stages they frequently sound like noisy tires...it can be hard to tell. I no longer have a local dealership so I'll have to wait until my next trip to Detroit in April to have it checked out.
