Just passed MOT adviser on front tyre

Got a worn front tyre. it’s worn between tread and side wall it’s done about twenty thousand mile . Could it be the camber angle bolt needing adjusting ? Help please

Always nice to hear these cars pass MOT, when did You last did the alignment, does it pull to one side ? could be wheel balance !

Had a track rod and fitted 2 years ago , I think it’s the camber angle bolt , the worn part is mainly on the outside wall of tyre . Ill take it to kwik fit . they got the tackle to do the job ,
