A sidewall blister or bubble can also be the result of an impact with some
object on the sidewall; such as a curb or any debris on the road.  It man
not manifest itself right away.  Sometimes after
a sidewall inspection; one can see a scuff mark in the area of the bubble.
The sidewall is not designed for impact; at least at a side deflection.
Kind of difficult to tell if it was a manufacturing defect; or from some
mishap.  Those tires were there has been a trend in getting sidewall bubbles
 one starts giving the benifit of the doubt there.

A bubble in the sidewall is usually a sign of an open ply splice, ply
has fabric in it to prevent stretching but the sidewall rubber doesn't
so it bulges if the ply isn't in that spot. This is very dangerous
and could blow at any time. Since it's a manufacturing defect I would
suspect Dunlop would have replaced it for free if you complained
loudly enough, especially with all the Firestone fiasco happening so
I don't know much about the sp5000, sorry.
