A noise
When I got out of my car a few minutes ago I noticed a loud noise coming from the rear driver side tire. Sounds like a hissing sound almost? Not like a belt or air leak or squeaky brakes. I just kind of want to know what this could be? I am hoping nothing to expensive. And this noise is happening when my car is completely off. I let it sit and about 30 minutes later went out to see if it had stopped and it hadn't. Any help would be appreciated.
