Best Practice for Replacing a Tire
When you’re on the road, it’s easy to get a flat tire. While changing a flat tire is relatively simple (especially if you have roadside assistance), if you don’t know what you’re doing, there’s a chance that it can become dangerous and even lead to injury. Here are some tips for changing your tires safely
Place the jack under the vehicle.
Place the jack under the vehicle.
Use a jack stand to support the car when it’s lifted off of its wheels.
Make sure that you are using the correct jack for your car, and make sure that it is correctly positioned underneath your vehicle.
The place where you position your jack depends on what type of car you have, as well as what kind of suspension (front or rear) it has. If you are unsure, consult with someone who knows more about cars than yourself!
Loosen lug nuts with the tire iron.
Once you have the wheel off, it’s time to loosen the lug nuts. You can use a tire iron for this step, but if you’re working with a large vehicle or need more leverage, use a socket wrench or breaker bar instead. The goal here is to loosen each nut just enough that they’ll come off easily when you remove them by hand.
To do this in a star pattern:
- Loosen each nut about 1/4 turn counterclockwise.
- Rotate the wheel and repeat until all nuts are loose but not completely off—you should still be able to turn them with your fingers.
Remove lug nuts and take off the tire.
- Loosen the lug nuts with the tire iron.
- Remove the lug nuts from all four tires, and remove them from their positions in their respective holes.
- Lower the jack until it rests firmly on the ground, then place it to one side of your car as you remove your spare tire from its storage space in your trunk.
- Take off your flat tire and replace it with a new one that is inflated to its recommended pressure level, then reattach all four lugs onto their corresponding wheels.
Replace the tire.
To replace the tire, use the jack to lift the car off the ground and place jack stands under it.
Remove all four lug nuts from one wheel with an impact wrench or breaker bar; keep them in a safe place for storage (for example, inside your trunk). Lift off the wheel and set it aside on its side so that if any fluid spills out of it, it will not get all over everything else. Do not set it flat on its face as this can damage both yourself and your car’s paint job!
Use an air compressor or bicycle pump to inflate new tires by 15 pounds per square inch (psi), which is approximately three times higher than normal inflation pressure (30 psi). This ensures that when they are installed they won’t deflate while driving down to lower pressures needed for optimal fuel economy. If using a bicycle pump develop good technique so as not waste energy while inflating tires – see video at end of page 12 in case study section below!
Remove rubber grommet from valve stem; insert new valve stem through center hole of wheel onto valve stem, then tighten against rim with wrench or pliers until snug but do not over tighten!
Put on the lug nuts.
Once the tire has been removed and you’re ready to put on your new one, start by tightening each lug nut in a star pattern. This means that you’ll tighten the lug nut farthest from the car first, then work your way around until all of them are snug but not too tight. It’s important to note that these nuts should be tight enough to keep things secure, but not so tight that they damage or strip out threads on the wheel itself.
Now that all of your lug nuts are tightened securely, lower down onto its tire valve stem (which should be pointing downwards). This will allow air pressure in as needed during installation and ensure proper inflation when done with installation. Once properly seated on its stem (which should be pointing downward), lower down onto its tire valve stem (which should be pointing downwards). This will allow air pressure in as needed during installation and ensure proper inflation once completed with installation.
Remove jack and lower car.
Now that you’ve removed all four wheels, it’s time to lower the car. You’ll need to remove a few more things in order to do this safely:
- Remove your jack and set it aside
- Lower the car
Tighten lug nuts in a star pattern.
- Don’t over-tighten. Use a star pattern to tighten the lug nuts and make sure they are snug, but not overly tight. You’ll want to be able to rotate them by hand once you’re finished with the job.
- Use the tire iron or wrench to tighten each one of your lug nuts in a star pattern, starting at one side of your vehicle and working around it until you reach all four corners. Be sure that each nut is tight enough so that it doesn’t move when pushed against—but don’t overdo it!
- After you’re done tightening, check all four tires for proper inflation (look for an inflation sticker on each tire), then get back in your vehicle and drive off into the sunset!
Changing a tire is a simple process. However, it can be dangerous if you don’t know what you are doing. The key to changing a tire safely is having the right equipment on hand, knowing how to use it properly, and keeping an eye out for anything that could go wrong. By following these instructions carefully, you should be able to change your tires without any problems!
