The purpose of this Safe Job Procedure (SJP) is to provide general step-by-step instruction on how to change a tire.
It is important to note that there may be some minor steps or processes that differ from this SJP and employees should always refer to their vehicle’s owner manual prior to starting the task.
You are encouraged to discuss with your supervisor if you are unwilling, uncertain or not comfortable with changing a vehicles’ tire prior to travelling on the highway or to remote areas where assistance may be limited. Other steps and/or processes may need to be put in place to ensure you have means to call for assistance should you need a tire changed.
Vehicle set up prior to beginning the task:
- Pull off the road as far as you can to avoid traffic, keeping both yourself and the travelling public safe from each other
- Find a level area in which to park the car prior to beginning any activities
- Ensure vehicles emergency/parking break is engaged
- Turn engine off and turn four-way flashers on. You may want to open the hood as a sign to indicate to other drivers that you’re stopped for repairs
- If your vehicle has emergency equipment, like triangles or pylons, set them up far enough from the rear of your vehicle to give adequate warning to approaching traffic
- Place an object in front or behind the tires on the opposite side to act as a wheel chock keeping the vehicle from rolling. You could use either a rock or log should you not have wheel chocks.
Performing the Task:
- Gather/Collect vehicle spare, the tire iron (lug wrench) and vehicle jack
- Visually inspect equipment listed above for signs of wear and tear, or cracks in the equipment prior to starting. If equipment looks faulty you’ll need to call/contact someone for assistance.
- Do not use poorly maintained or faulty equipment to perform this task
- Attempt to loosen lug nuts prior to jacking the vehicle – rotate lug nuts left (counter-clockwise) to loosen
- Loosen lug nuts following a star pattern, until all of the lug nuts have been slightly loosened
- Place vehicle jack in the spot indicated in the owner’s manual
- Slowly jack the vehicle, observing the stability of both the vehicle and jack as weight is transferred
- Raise the vehicle just high enough for the tire to spin freely to ensure smooth transition between removing the old tire and replacing with the new one
- Remove the lug nuts and store them in a safe place
- Carefully support and remove the defective tire from the vehicle and set on the ground away from oncoming vehicle traffic
- Lift the replacement tire onto the wheel studs, ensuring that the tire valve is facing you
- Replace the lug nuts on the wheel studs and begin to hand tighten – in the star pattern prior to using the wrench
- Tighten all lug nuts until snug and rim is tight to hub
- Slowly lower the vehicle on the jack, until most of the weight is on the tire
- Again using the star pattern, use the tire iron to completely tighten the lug nuts on to the vehicle’s wheel studs
- Remove jack from under vehicle and place out of the way of oncoming traffic
- Perform an additional check of the lug nuts to make sure they are tight and secure, using the tire iron
- Replace hubcap if present, and return tools and damaged tire securely in their designated spots
- When lifting and carrying tire. Awkward positions can cause back strains
- Removing the old tire from the vehicle, as strands of steel may be sticking through the tire causing injury
- Using the jack as cars can easily slip off if the process is not done correctly
- It is a good idea to quickly check your vehicle’s spare tire before getting on the highway for long distance trips. A flat spare is no good to anyone
