We replaced this one. It was making a bumping noise on our church van. The tire shop guys were afraid to go near it.
Thank goodness nobody got hurt! This is from a few years back.
I think if I worked in a tire shop and saw that come in... I'd probably be a former employee!
Just how does one handle that? Guy who draws the shortest straw? I mean, I'd be afraid to walk near it, let alone touch it. Once the air is out it's probably fine, it's the getting to that part that would worry me... maybe remove the valve core and run...
