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.
Use the jack to lift the vehicle. You can use the user manual to ascertain if it matches that weight. Offload any extra cargo from the lorry before lifting the vehicle. If you are not sure of the amount it can lift, you can use the manual. Some are meant for small vehicles.
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.
Loosen the nuts until they are a few steps away from coming out of the wheel. Turn the jack to lift the tires that you want to operate on. Turn it until it is above the ground. While turning it, do not let any part of your body to lie under the truck, since a slight mistake might get the truck hit you
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.
