I have a little problem with my car where it makes this humming noise lets say from 20 mph and increases with speed. The thing is that i had a little acciddent a while ago and my both wheels on the drivers side were bent and during the accident one tire came off. Then i went to a tire place to put it back on and when they were doin it they didnt bother balancing the tires since the wheels were damaged. I didnt replace the wheels yet but have this noise ever since. The bodyshop fixed everything besides the wheels cause he couldnt get ahold of them in time so he gave me the money and im gonna do it in couple of day..... i was just wondering what that noise might be related to. Bent wheels... or unbalanced tires or maybe something else ???

 

i had a weird sound comming from the rear of the car especially the left side.......I ended up getting new wheels and tires and it seems to be fine now......

 

the humming could be the tire vibrating pretty badly, like a pulley.
