Honda makes very good vehicles, but the universal complaint--even on their higher-priced Acura models--is a high level of road noise. Throw some worn tires into the mix and you wind up with the perfect storm for excessive road noise.
Now, the problem will be finding out why your tires got so badly worn in only 9k miles!
As CapriRacer stated, you need to have a 4-wheel alignment done. And, if you don't own a tire pressure gauge, you need to get one and use it on a regular basis to be sure that the tires are properly inflated. You will find the correct inflation pressure listed on a label on the driver's door jamb. Do NOT inflate the tires to the maximum pressure listed on the tire sidewall.
