As this thread has now gone off on a tangent and missed my original personal original point, I will re-state it.
A large percentage of these second hand tyres come from written of vehicles.......i.e., they have suffed an accident bad enough to cause them to be beyond economical repair.
Now clearly if you buy a second hand car, its normaly pretty obvious the state the car is in and hence you have a much smaller risk (and its all about risk here)
And as for the second hand tyre seller saying its the likes of the Germans dumping good tyres when they change to winter ones, thats a load of rubbish as they have a second set of steel wheels with the winter tyres on (as you dont want chains on good alloys ideally!).
Now clearly an inspection is a way of helping to minimise the risk but, I personaly wont use them until there is a compulsary tyre test introduced for them which is carried out before they are sold (and to me its crazy there isnt as they are sold as fit for purpose).
