One of the most dreaded things that motorists get is having a flat tire. Truck drivers suffer a lot when the vehicles get a damaged tire. However, there is a simple step by step that they can change the tires even in the absence of a mechanic using a roll on trailer jack. However, they need to ensure that it is in the right place.
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.
Check whether the available jack is able to lift the trailer. You will find their specifications in the buyer manual. If the lorry is heavily loaded, offload some cargo until the truck attains the right mass. All of them come with a user manual to show how much weight they can lift without straining. Do not use one which can only support small weight since it will be damaged.
Put bricks or other strong blocks both on the front and back points of the tire to prevent them from rolling. Ensure that they are in contact with the tires to prevent slight movements which might take place as you operate on the deflated tire. Put a piece of wood or another material that cannot scratch the vehicle as you operate on it.
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.
Remove the nuts from the wheel and take the wheel out. If you observe any noise from the point where it contacts with the body of a vehicle, scrutinize whether it is as a result of it coming out of its place. It is dangerous to change a tire with it out of place since the vehicle might lose balance and fall on you. If there is luggage on the lorry, it is advisable to remove it before changing the tire.
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.
