There were some good tips posted on here about changing a punctured wheel.
MFH; Put the 'taken off' punctured wheel under the car, next to the Jack, just in case.
Octy; Bump the spare wheel off the punctured wheel to loosen it if required.
Utube man; Put a Brick or Stones under the opposite far side wheel fer cars with 'Dodgy' auto hand-brakes, just to be sure.
