Sometimes it seems the roads have it in for us and our tyres can’t cope. If you are like the many that do not have the pleasure of having run flat tyres you may have to experience the ‘fun’ of waiting on the hard shoulder for a breakdown recovery team. This week’s tips give advice on how to change car tyres, from IAM RoadSmart’s head of driving and riding standards Richard Gladman.
If it is possible pull off the road to a safe secure area – changing a wheel with traffic inches away from you is not safe. If you have to stop on a road, place your warning triangle at least 45 metres behind your vehicle. Activate your hazard warning lights to warn other traffic. Raising the bonnet or hatchback will help other traffic realise you have an issue. If you have a passenger get then to act as spotter and warn you of approaching traffic
A level hard standing will be best, soft ground will not allow the jack to be used correctly. If the ground is not suitable you may need assistance from a professional.
Locate the jack and wheel brace, it may help if you do this during your weekly vehicle checks so you know where it is and how to release it. This is also a good time to locate the jacking points and find out how the jack works. Often the kit will have a wheel chock; use this on the other axle of the vehicle to assist keep it still.
Loosen the wheel nuts slightly before you start jacking the car up, the vehicle will be unstable after you raise it and you will not be able to get as much leverage. Remember one of the nuts is likely to have a lock function and will require the unique key.
When jacking the vehicle you will need it to be raised high enough to fit the new tyre (this will be higher than required to remove the old). Wear gloves when handling the old tyre, if it has punctured it is likely to have sharp steel protruding from it.
Tighten the wheel nuts until the wheel sits squarely on the hub and then lower the jack. Further tighten the wheel nuts with the vehicle stable. You will need to get the wheel nuts checked for tightness by a professional (when you repair or replace the punctured tyre). If fitting a space saver spare, remember the restrictions that imposes i.e. no more than 50mph (80kph) and should be used to get you to a place of repair – not as a substitute for the correct tyre.
Avoid changing your wheels on the hard shoulder of a motorway. If you have a puncture on a motorway, contact the Highways Agency or the police for assistance before you attempt any repair. They will attend and assist to make the area safe for a tyre change to be conducted.
Richard said: “Punctures are much rarer these days but the risk associated with conducting a tyre change has increased with the volume of traffic. Safety has to be your main concern if you cannot get to a safe area to make the change; get the vehicle off the road and call for assistance. A vehicle recovery service will have access to professional equipment which will allow a much speedier repair to be conducted. If you are in any doubt, call for help.”
