Well point 2 is that i bought the car the day before, they were fine as i checked and that the hole was about half a mile from home and next morning i noticed the tyre was flat. once i see about the wheel and tyre later today i am getting the other bits checked.
i suffer from a bad back, so avoid pot holes like the plague and can usualy spot them well in advance, even speed bumbs i have to almost come to a crawl.
