Start by getting somewhere safe.

  1. 1Pull over somewhere flat and firm, well away from traffic. Hazard lights and parking brake on; everyone out.
  2. 2Wedge the wheel diagonally opposite the flat.
  3. 3Get out the spare, the jack and the lug wrench.
  4. 4Loosen each lug nut half a turn, anticlockwise, while the tire is still on the ground.
  5. 5Jack the car up at the jack point in your manual until the flat is off the ground.
  6. 6Take the nuts off and pull the flat straight off.
  7. 7Put the spare on and thread the nuts on by hand.
  8. 8Lower the car and take the jack out.
  9. 9Tighten the nuts fully, in a star pattern across the wheel.
  10. 10Check the spare's pressure, pack up, and get the flat fixed.

Safety

  • Never change a tire on a busy road, a hard shoulder, a slope or soft ground: drive slowly somewhere safe, or call roadside assistance or the police.
  • Never put any part of your body under a car held up only by a jack.
  • Use the jack points and lug-nut torque in your owner's manual, and keep to the speed and distance limits printed on a temporary spare.
