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.
Drive the truck to level ground. Do not park it at the roadside, since it might roll to the side. If you do not find a level field, park it on one side of the road and place warning signs and turn on both the indicator lights and the headlights to warn other motorists that there is some 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.
Put some objects behind the wheels to prevent the tires from rolling, as this is dangerous. Ensure the objects are in contact with the wheels to prevent any slight movement. Put a small object on the car jack that cannot scratch off the paint. If you are using a metal object to lift the car, you can cover it with a piece of paper.
Start to roll on until the part of the wheel you want to operate on stands on the stands. At this point, it does not change the blocks on the other wheels since the wheels might start to move and hit you in the process. Avoid lying under the car while operating vehicle, especially if the engine is running.
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.
After you have changed the tire, turn the jack in the opposite direction to lower the lorry to ground. Remove the blocks that you had used to prevent the wheels from moving out of the way. Drive for a short distance to check if the vehicle is in the right condition. If you observe some bouncing movements on the tire, check for pressure and inflate the other tires until they attain a similar weight.
