Default Vibration/road noise on the highway

Hi all. My Rx300 recently developed some strange problem:

1. Vibration on the highway. High frequent vibration, seems related with wheel rotation.

2. Accompanying with road noise. My RX300 is very quite before when I drove on highway, but now it developed some road noise. The noise frequency is the same as wheel rotation.

3. It seems not related to engine, because it happens no matter I press the gas pedal or not.

4. Brake is not smooth, light jerks follows a certain pattern when wheel rotates.

5. Transmission shifts ok, smooth.

6. No CEL comes

It looks there is something wrong with my tire/wheel. How can I identify it? Thanks.

Possibly a wheel bearing(?)

^^^I'm thinking the same for my car.

But, lohn, when's the last time you had your tires balanced, rotated and aligned? It would probably shake the wheel more coming to a stop if you're out of balance/alignment, if I am correct.

Others will probably be able to offer more pinpointed suggestions.

@DeadRX, I think it is 3 years ago......... I will go to a tire store to examine it tomorrow.
