An interesting story, and no doubt related to a discussion about tyres, but as we have no infomation on the tyre, age, history, state of inflasion its doesnt really detract or support the OPs request. We dont even know it was fitted from new or not.At the front was a Minibus with a woman driver and full of old people... As it slowed down a tyre came off and sped across all the lanes to end up inside the central reservation...
The discription also makes it sound more like the whole wheel parted company rather than just the tyre, as Ive never seen a tyre come off a wheel and carry on over three lanes in such a way, although obvuiously I wasnt there.
