Its possible that an airbag blew, but you would have noticeable sag in the rear, and your compressor would be running constantly. I have heard stories of how loud the airbags are when they explode; they apparently sound like a gunshot.The noise that sounded like we blew a tire is what most worries us...there was a pop sound and then a sound like air coming out of something. Did we pop an air bag? Or could it be a hose that the air was coming out of? It still kicks on like it should and kicks off so I am assuming it "comes to pressure".
