Getting a flat tire is one of the most discouraging things to a driver. If you ever find yourself in this situation with a trailer, you can use a roll on trailer jack to change the deflated tire. There are several steps that you can use to repair it with a lot of ease, without involving a mechanic.
The first step is to move the lorry to an area where the vehicle cannot fall. Preferably, park in a flat area. After parking the car, the driver should turn off the engine but leave the indicator lights and headlights on, to caution other travelers from bumping on it. You should also use a road sign to inform other drivers that there is maintenance going on.
Change the gear from the drive gear and let it rest on a parking gear to prevent the lorry from moving when changing the tire. The driver is also advised to engage any traffic officer on sight to warn other road users that there is maintenance going on. This method is applicable if the vehicle is being prepared by the highway.
Before using the lorry, you should check whether it has been recommended for that particular weight. Some jacks are recommended for small vehicles with a low mass, while other jacks are designed for heavy trucks. If you are not sure of the weight the jack can lift without problems, and you can check out from the user manual which gives a guide on the same.
Use wedges or other objects to block the wheels from moving as you operate on this tire. Once you have confirmed that the wheels are intact, place a wooden or plastic object on this jack. This is to ensure that it does not come into contact with the surface of a lorry since it might damage the part of this truck.
Roll the jack to lift the tire off the ground until it is left supporting the vehicle. Do not distract the blocks supporting the wheels, since a slight movement might cause it to move out of its place. Do not put any part of your body under it so that you do not get hit in case of any malfunction.
Use a spanner to loosen the nuts from the wheel. While removing them, observe if the lorry is making some noise. If there is some noise, find out whether the roll on is in position, since the sound might be caused by it moving out of its first place. If it has run out of its position, lower it until the tire gets to the ground and return it to its location.
Put on a spare and tighten the nuts again until they get to their correct position. Roll on in the opposite direction until the tire gets to the ground then tighten the nuts. Remove the blocks from the other wheels and turn on the engine. Put the truck on a road test and correct any problem that might arise. Return the tools to the toolbox and proceed with the journey.
