i just noticed that on my back tire driver side that is that the tires somehow got worn down with peaks and valleys and now its is noisey as all get out and starts to shake the car too, how did this happen?

 

get it replaced. It's called seperation. the steel belt's are "lifting" off of the casing of the tire. This creates the bump. It can stay like this for a long time, or it could "let go" tomorrow!

 

If its a newer tire you might be able to get a refund, contact a tire place near you that deals in them, buy a new one, and have them send the other back. They usualy get refunds in in a couple of weeks, if applicable.

I had that happen to me on a brand new tire not long back, did the same thing.

Not sure if they are newer or not, but under warranty either way gets you some kind of refund.

 

thanks for the feedback def need to get it checked out
