Knowing how to change a tyre is a necessary skill for all drivers. If you rely on a mobile phone to save you in a roadside emergency, there’s always that chance your cell phone may be left at home, out of battery or without a connection. Flat tyres can happen anywhere, and a mobile phone is no substitute for knowing how to change a flat tyre.
Thankfully, changing a tyre isn’t all that hard! Just adhere to the following guidelines to be prepared in case you have a flat.
Items You'll Need to Fix a Flat Tyre
These items should have come with your vehicle:
- Lug wrench
- Fully inflated spare tyre
- Vehicle owner’s manual
If you have misplaced any of these items, or if your car did not come with these items, you should purchase new ones right away. And be sure you’re regularly inflating the spare tyre according to your vehicle manufacturer’s recommended PSI. You should check the spare tyre’s air pressure every time you check your other tyres. Remember to check tyres pressures every month, before long trips or when you are carrying the extra load.
Here are some items that don’t come with your vehicle but you should store in your trunk or glove box compartment in case you have to change a flat tyre:
- Flashlight with working batteries
- Rain poncho
- Small cut of 2"x6” wood to secure the jack
- Wheel wedges
How to Change Tyres
1. Find a Safe Location
As soon as you realise you have a flat tyre, do not abruptly brake or turn. Slowly reduce speed and scan your surroundings for a level, straight stretch of road with a wide shoulder. An empty parking lot would be an ideal place. Level ground is good because it will prevent your vehicle from rolling. Also, straight stretches of road are better than curves because oncoming traffic is more likely to see you.
Never attempt to change your tyre on a narrow shoulder near oncoming traffic. Keep moving (slowly) until you find a safer spot. While driving on a flat tyre risks ruining your rim, replacing a rim is better than being hit by an inattentive driver.
Make sure to consult your owner’s manual and review their specific steps on how to change a flat tyre for your vehicle.
2. Turn on Your Hazard Lights
Your hazard lights or “flashers” will help other drivers see you on the side of the road. To avoid an accident, turn them on as soon as you realise you need to pull over.
3. Apply the Parking Brake
Once stopped, always use the parking brake when preparing to replace a flat tyre. This will minimise the possibility of your vehicle rolling.
4. Apply Wheel Wedges
Wheel wedges go in front of or behind the tyres to further ensure the vehicle doesn’t roll while you fix the flat tyre. If you’re changing a rear tyre, place these in front of the front tyres. If your flat tyre is at the front, put the wheel wedges behind the rear tyres.
Bricks or large stones will work just as well as “real” wheel wedges. Just be sure they’re large enough to stop the car from rolling.
5. Remove the Hubcap or Wheel Cover
If your vehicle has a hubcap covering the lug nuts, it’s easier to remove the hubcap before lifting the vehicle with the jack. If your lug nuts are exposed, you can skip ahead to Step 6.
Use the flat end of your lug wrench to remove the hubcap. This will work for most vehicles, but some hubcaps need a different tool to come off. Consult your owner’s manual for proper hubcap or wheel cover removal procedures.
6. Loosen the Lug Nuts
Using the lug wrench, turn the lug nuts counterclockwise until you break their resistance. You may have to use force, and that’s fine. Use your foot or all of your body weight if necessary.
Loosen the lug nuts about ¼ to ½ of a turn, but don’t remove them completely yet. Save that for when it’s time to remove your tyre/wheel from the vehicle.
7. Place the Jack Under the Vehicle
The right place for the jack is usually beneath the vehicle frame alongside the tyre that’s flat. Many vehicle frames have moulded plastic on the bottom with a cleared area of exposed metal specifically for the jack. To safely lift and avoid damage to the vehicle, follow the instructions for jack placement in your vehicle owner’s manual.
8. Raise the Vehicle With the Jack
To prevent the jack from settling under the weight of your vehicle and coming off balance, place a small cut of wood (2" by 6") beneath it before attempting to raise your vehicle. This tactic is especially helpful on asphalt.
With the jack properly positioned, raise the vehicle until the flat tyre is about six inches above the ground.
Never put any part of your body under the vehicle during or after raising the vehicle with the jack.
9. Unscrew the Lug Nuts
Now it’s time to remove the lug nuts all the way. Since you've already loosened them, you should be able to unscrew them mostly by hand.
10. Remove the Flat Tyre
Gripping the tyre by the treads, pull it gently toward you until it’s completely free from the hub behind it. Set it on its side so that it doesn’t roll away.
11. Mount the Spare Tire on the Lug Bolts
Now place the spare on the hub by lining up the rim with the lug bolts. Push gently until the lug bolts show through the rim.
12. Tighten the Lug Nuts by Hand
Put the lug nuts back on the lug bolts and tighten them all the way by hand. Once they are all on, check each one again, making sure that it’s tightened as much as possible. You will tighten them with the wrench after lowering the vehicle to the ground.
13. Lower the Vehicle and Tighten the Lug Nuts Again
Use the jack to lower the vehicle so that the spare tyre is resting on the ground but the full weight of the vehicle isn’t fully on the tyre. At this point, you should tighten the lug nuts with the wrench, turning clockwise, as much as you can. Push down on the lug wrench with the full weight of your body.
14. Lower the vehicle completely
Bring the vehicle all the way to the ground and remove the jack. Give the lug nuts another pull with the wrench to ensure they’re as tight as possible.
15. Replace the Hubcap
If the hubcap you took from the flat tire will fit your spare, put it in place the same way you removed it initially. If it doesn’t fit, stow it away with the tire when you stow your equipment.
16. Stow All Equipment
You have before you a jack, a lug wrench, wheel wedges, your flat tyre, and possibly a hubcap. Don’t forget to put all of them in your vehicle before driving away.
17. Check The Pressure in the Spare Tyre
You should check the tyre pressure of the spare tyre to make sure that it is safe to drive on. “T-Type” temporary spares, also called “mini-spares,” require 60 psi (420 kPa). If the tyre needs pressure, drive (slowly) to a service station immediately. The pressure may differ for different vehicle. Please verify the information on your vehicle manual.
18. Take Your Flat Tyre to a Technician
Temporary spare tyres aren’t made to drive long distances or at high speeds, so drive cautiously until you’re able to visit a tyre technician. A professional should be able to determine whether your tyre needs a repair or if it’s time to replace it.
How Long Does it Take to Fix a Flat Tyre?
Aside from taking your tyre to a professional, changing your tyre shouldn’t take more than 15 to 30 minutes. Just be sure you don’t leave out any steps.
It’s beneficial to practice changing a tyre in your garage or driveway to ensure you’re ready to handle this situation if it ever happens to you.
A Few More Tips on Changing Tyres
Knowing how to fix a flat tyre is great, but regular tyre maintenance is even more important. In addition to reviewing this guide regularly, remember to do the following:
- Keep your tyres properly inflated
- Rotate your tyres according to the manufacturer’s guidelines
- Monitor for tread wear
All of these precautions will extend the life of your tyres and reduce the likelihood of a flat. While there’s no way to prevent flat tyres completely, proper care can improve performance and ensure your tyres last as long as possible.
