Sounds like a possible wheel bearing noise when decelerating only. 2008 Pontiac Montana. I thought noise was from new tires against pavement when braking. Noise level is increasing and is noticable when decelerating now.

SOURCE: rear wheel/brake noise

first check condition of discs and pads if all is good drive and pull up handbrake slowly to see if its the handbrake shoes making the noise if still a problem will most probably be rear wheel bearings

SOURCE: Grinding noise in the left

grinding on front wheel is caused by 2 things. a bad or loose wheel bearing,or worn out brakes, have them both checked
You might also want to check the level of fluid in the power steering reservoir - low or lack of fluid will also cause a noise (although more of a whining than a grinding).

SOURCE: right front wheel plan and road noise

DON'T FORGET TO RATE:

SOURCE: Rotating wheel noise from front end

That is the bearings going bad on it.

SOURCE: Noise from rear wheel area that sounds like bearing noise.

Might want to check your camber adjustments and look into shocks and struts. They could all be worn out but prolly the camber is off causing abnormal road noise and abnormal tire wear
