It's cold, it's dark, you're late
and it's raining. Punctures always seem to pick the worst moment to happen. If
your car gets one and you're away from home on the move, the first priority is
to get it - and you - to a safe place.
Drive slowly, at no more than 5mph,
on the punctured tyre until you are out of danger. On the motorway, this will be
the hard shoulder, though you should not attempt to change a tyre on the hard
shoulder as this can be dangerous - instead, walk to the nearest emergency
telephone to call for help. On a busy A-road, select a lay-by, another parking
place or a side turning. Wherever you choose must be a level surface and,
preferably, well lit.
Difficulty rating:
beginner
Time to allow: 30min
Tools/ materials needed: wheel
brace, jack, clean rag, torch (if dark), warning triangle, breakdown kit.
Having moved the car to a safe spot
(see above), switch on the hazard warning lights, turn off the engine and apply
the handbrake. If the transmission is manual, select reverse gear; if it's an
auto, select 'park'. If you carry an emergency warning triangle, place this a
fair distance behind the car - 50m if possible.






1) Get all passengers out of the car and safely away from the road. Remove
luggage from boot if heavy or if it's obstructing access to the spare wheel and
tools.
2) Check that the spare tyre feels adequately inflated and that the jack and
wheel brace are present and serviceable. Remove spare and tools from car.
Consult vehicle handbook (if available) for detailed instructions.
3) Remove plastic wheel cover (if fitted). Prise this off using the end of the
wheel brace if necessary. Then, using the brace, loosen the nuts on the wheel
you intend to change by half a turn. If they are stiff, use your body weight on
brace to shift them.
4) Use the jack to raise the wheel, first consulting the handbook to find the
correct lifting point on the car that's nearest the wheel you are replacing. Do
not jack using any other point - it may collapse and seriously damage the
bodywork.
Once the car body is raised sufficiently (but before the wheel you
are raising is off the ground) push the spare wheel under the body. This will
act as a safety cushion should the car slip off the jack.
5) Keep raising the car. Once the wheel is just clear of the road, unscrew the
nuts in diagonal pairs and remove. Place together in a hat, pocket or drinking
cup so they are not lost.
6) Remove wheel. Take care, though, because it will be heavy and dirty.
Place the wheel flat under the raised sill of the car as an extra back-up in
case the jack should slip. Warning: a car can easily slip off the jack, even on
a level surface. Never get under the vehicle while only the jack supports it.
7) Fit the spare. Ensure it is the correct way round. Fit wheel nuts in diagonal
pairs and turn until finger-tight.
Using the jack, lower the car until the
tyre of the replaced wheel just touches the road. Then, using the wheel brace,
lightly tighten the wheel nuts. Remove the punctured wheel from under car.
Finish lowering the vehicle and remove jack. Fully tighten wheel nuts. Put your
tools and damaged wheel in boot. If the wheel had a plastic cover, refit
it.
If the spare is of a 'space saver' type you should not exceed 50mph while
fitted, and you should also replace it with a full-size wheel and tyre as soon
as possible. If the spare is full-size, you can leave it on the car but you
should still have the punctured tyre repaired or replaced as soon as possible.
