Dealing with a flat tyre can be stressful, especially if you’re on the road without immediate help nearby. Having a tyre changing kit in your vehicle can be a lifesaver, but it’s equally important to know how to use it properly and safely.
Changing a tyre is a task most vehicle owners will face at some point, and doing it wrong could lead to dangerous situations or further damage to your vehicle.
What’s Inside a Tyre Changing Kit?
Before diving into the steps and safety tips, it’s important to know the basic components of a typical tyre changing kit. A standard kit usually contains the following:
- Spare Tyre – A compact, temporary “donut” tyre or a full-sized spare.
- Car Jack – A mechanical tool used to lift the vehicle off the ground.
- Lug Wrench – A tool used to remove and tighten the lug nuts that secure the tyre to the car.
- Wheel Wedge/Chock – A wedge to prevent the car from rolling while it’s lifted.
- Gloves – To protect your hands while handling dirty or hot components.
Now that you know what’s in the kit, let’s go over some essential tips for using it safely.
1. Choose a Safe Location
The first and most critical step when you discover you have a flat tyre is finding a safe location to pull over. Try to move your car to a flat, level surface away from traffic.
If you’re on a busy road, look for an emergency lane, rest area, or parking lot. Avoid soft or uneven ground like sand or gravel, as it may make jacking up your car unsafe.
Once you’ve found a safe location, turn on your hazard lights to make your vehicle more visible to other drivers. If you have road safety equipment like cones or reflective triangles, place them behind your car to alert oncoming traffic.
2. Use Wheel Wedges for Stability
Before you start using your car jack, ensure that your car is stable by placing wheel wedges or chocks behind the wheels opposite to the one you’re changing.
For example, if you’re changing a rear tyre, place the wedges in front of the front wheels to prevent the car from rolling. This is especially important if you’re working on a hill or slope, but it’s a good safety practice regardless of the surface.
3. Loosen the Lug Nuts Before Lifting the Vehicle
One common mistake many people make is trying to remove the lug nuts after the car is already jacked up. This can be dangerous, as the vehicle may become unstable or shift while you’re applying force to loosen the nuts.
Before using the car jack, use the lug wrench to break the lug nuts loose.
Turn the wrench counterclockwise until the lug nuts are loosened but do not remove them completely at this stage. Loosening the nuts while the car is still on the ground will make the process safer and easier.
4. Correct Use of the Car Jack
When it’s time to lift the car, make sure to position the car jack under the vehicle at the proper jacking point. Most cars have reinforced areas designed for jack placement, usually indicated in the owner’s manual. Using the wrong spot can damage your car or, worse, cause the jack to slip.
Once the jack is in place, raise the vehicle until the flat tyre is off the ground. It should be high enough for the replacement tyre to fit easily under the wheel well.
While raising the car, do it gradually and keep checking that the jack remains stable. Never get under the car while it’s lifted, as jacks can sometimes fail.
5. Remove the Flat Tyre Safely
Now that the car is lifted and the lug nuts are loosened, you can completely remove the lug nuts. Place them somewhere safe, like a pocket or container, so they don’t roll away.
Carefully pull the flat tyre straight toward you until it’s completely off the hub. Tyres can be heavy, especially full-sized ones, so take your time and avoid straining your back.
6. Install the Spare Tyre Correctly
Take your spare tyre and align the holes on the wheel with the lug nut posts on the hub. Once aligned, gently push the spare tyre into place until it’s flush against the hub. Put the lug nuts back on by hand, turning them clockwise until they’re snug but not fully tightened.
7. Lower the Vehicle and Tighten the Lug Nuts
After the spare tyre is securely in place, lower the car back to the ground using the jack. Once the tyre is touching the ground and the vehicle is stable, use the lug wrench to tighten the lug nuts as much as possible.
It’s best to tighten them in a star or crisscross pattern to ensure even pressure on the wheel. Tightening one nut fully before moving to the next can cause uneven stress on the wheel.
8. Check the Spare Tyre’s Pressure
If possible, check the pressure of your spare tyre with a pressure gauge before driving. Most temporary spare tyres are designed to be inflated to a higher pressure than regular tyres, often around 60 PSI. Driving on an underinflated spare can be dangerous, so make sure it’s properly inflated.
9. Drive Carefully on a Spare Tyre
Spare tyres, especially compact ones, are designed for temporary use only. They typically have less traction and durability than regular tyres and should only be driven for short distances at reduced speeds, usually no faster than 50 mph (80 km/h).
Once you’ve changed the tyre, head straight to a mechanic or tyre shop to have the flat tyre repaired or replaced.
10. Regularly Maintain Your Tyre Changing Kit
A tyre changing kit is only as good as the condition it’s in. Periodically check that your spare tyre is properly inflated and that all the tools in the kit are in good working order.
Ensuring that your kit is ready to go will give you peace of mind in case you ever face an emergency.
Conclusion
Knowing how to use a tyre changing kit safely is an important skill for every driver. By following these essential tips — from choosing a safe location to properly using the car jack and tightening the lug nuts — you can change your tyre with confidence and avoid potential hazards.
Regularly maintaining your kit and being mindful of how you drive on a spare tyre will keep you prepared for unexpected situations on the road.
