IIRC the hubs are slightly stronger than the nuts threads, so i'd imagine they will be fine. Have you used a breaker bar on it? As said blow torch from behind
and try and shock it. Which bit is spinning btw, the surround on the nut?
On a seperate note, it winds me up to fcuk how many people put on locking wheel nuts tight. WHY!!!!!! No offense mate (it might not have been you), but it's such a school boy error. No need what so ever. Ok, rank over
Hope you get it sorted matey
