You might think your cars wheel changing tools are of little significance to your safety; but every day in New Zealand there are people risking their lives driving on unsafe tyres which they could not change due to not having the correct tools.
We should always check the vehicles tools when buying a secondhand vehicle and confirm it has a jack, wheel nut spanner and a lock-nut key/security key if required.
It really is a good idea to trial fit the lock-nut key to make sure it is correct and ensure the spanner fits the wheel nuts and is thin enough to access them when they are in a recessed location on the wheel rim. A lot of modern rims need a “thin walled” socket to remove the wheel nuts as a standard socket will be too thick to fit between the rim and the wheel nuts.
It is not possible to change flat or damaged tyres when any of the above tools are missing and forces people to continue driving on extremely dangerous tyres with bulges and separating tread etc. Sure you can often borrow a jack and a spanner, but finding a thin wall socket when you need one will be very difficult and finding a lock-nut key to fit your vehicle will be impossible!
So check your vehicles for tools when you buy them and also after they come back from mechanics, panelbeaters and tool shops. They tend to be very busy guys and being human, sometimes forget to return the lock-nut key to the vehicle.
Finally, we have recently come across 2 quite expensive vehicles fitted with runflat tyres which were not supplied with lock-nut keys. It seems the car company regarded the lock-nut key as an “optional extra” arguing that their customer would always return to their workshop everytime they got a puncture; hardly helpful on a Sunday or if you are miles away from the nearest branch of that car company.
