Changing a wheel requires a spare wheel, lug wrench, jack, and wheel wedges. The process involves loosening wheel bolts, lifting the vehicle, removing the flat wheel, fitting the spare, and lowering the car safely. This essential skill keeps you mobile when punctures occur unexpectedly.
Tools and parts required
Having the right equipment makes wheel changing straightforward and safe. Check your boot regularly to ensure all items are present and in good condition.
Parts needed:
- Spare wheel (full-size or temporary)
- Wheel bolts (if damaged)
- Valve caps
Tools required:
- Lug wrench or wheel brace
- Vehicle jack
- Wheel wedges or chocks
- Gloves for grip and protection
- Torch or mobile phone light
Safety precautions
Park on level, stable ground away from traffic. Apply the handbrake and turn on hazard lights. Never change a wheel on a motorway hard shoulder – call for professional assistance instead.
Check your spare wheel pressure monthly. A flat spare wheel renders the whole exercise pointless and leaves you stranded.
Professional tip: Our mechanics recommend checking your spare wheel pressure every month during routine maintenance. A deflated spare wheel is useless when you need it most.
Step-by-step instructions
Step 1: Prepare the vehicle
Engage the handbrake fully and turn on hazard lights. Place wheel wedges behind the wheels diagonally opposite to the punctured wheel. This prevents the vehicle rolling during the process.
Remove the spare wheel, jack, and lug wrench from your boot. Some vehicles store these under the boot floor or clipped to the boot sides.
Step 2: Loosen the wheel bolts
Remove the wheel trim or centre cap if fitted. Locate all wheel bolts and position the lug wrench securely on each bolt. Loosen each bolt by turning anticlockwise, but don’t remove them completely yet.
The wheel’s weight on the ground provides resistance, making this easier before lifting the vehicle. If bolts are very tight, use your foot to apply extra leverage on the wrench handle.
Step 3: Lift the vehicle
Locate the correct jacking point near the punctured wheel. Your owner’s manual shows these reinforced points designed to support the vehicle’s weight safely.
Position the jack securely and raise the vehicle until the flat wheel is completely off the ground. Ensure the jack remains vertical throughout the lifting process.
Step 4: Remove the damaged wheel
Fully remove all loosened wheel bolts and place them in a safe location where they won’t roll away. Pull the wheel straight towards you to remove it from the hub.
Flat wheels can be heavy, particularly on larger vehicles. Get a firm grip and lift with your legs, not your back, to avoid injury.
Step 5: Fit the spare wheel
Align the spare wheel with the wheel bolts and push it fully onto the hub. Replace all wheel bolts and hand-tighten them to hold the wheel in position.
Using the lug wrench, tighten the bolts in a star or cross pattern. This ensures even pressure distribution and proper wheel seating on the hub.
Step 6: Lower and secure
Lower the jack until the spare wheel touches the ground but still supports some vehicle weight. Fully tighten all wheel bolts in the star pattern using firm pressure.
Lower the vehicle completely and remove the jack. Give each bolt a final check to ensure they’re properly tightened. Store the punctured wheel and tools in your boot.
Expert advice: AutoPartsPro specialists recommend checking bolt tightness after driving 50 miles, as bolts can settle and require retightening for safety.
Common mistakes to avoid
Many drivers make basic errors that compromise safety or damage their vehicle. Understanding these pitfalls helps ensure a successful wheel change.
Never attempt to change a wheel on soft ground where the jack might sink. The vehicle could slip off the jack, causing serious injury or damage.
Avoid using the wrong jacking points, as this can damage the vehicle’s bodywork or suspension components. Always consult your owner’s manual for correct locations.
Don’t forget to check the spare wheel pressure before driving. Many space-saver wheels require higher pressures than standard wheels.
Failing to tighten wheel bolts properly can result in the wheel coming loose whilst driving – a potentially fatal situation.
When should you change a wheel?
Change a wheel immediately when you notice a flat tyre or significant pressure loss. Driving on a flat tyre damages the wheel rim and potentially affects other vehicle systems.
Modern tyre pressure monitoring systems alert you to pressure drops. Don’t ignore these warnings, as running on under-inflated tyres increases puncture risk.
If your vehicle pulls to one side whilst driving, stop safely and check for tyre damage. What appears to be a slow puncture can rapidly become a complete deflation.
Replace space-saver spare wheels with proper tyres as soon as possible. These temporary solutions have speed and distance limitations clearly marked on the sidewall.
Related maintenance you can do at the same time
Whilst changing the wheel, inspect the brake pads through the wheel spokes. Thin pads or grinding noises indicate replacement needs.
Check the condition of remaining tyres for uneven wear patterns. This might indicate alignment issues, suspension problems, or incorrect tyre pressures.
Examine suspension components visible around the wheel area. Look for oil leaks from shock absorbers or damaged rubber boots.
Consider checking your battery terminals if you’ve used hazard lights for extended periods during the wheel change.
Frequently asked questions
How tight should wheel bolts be?
Wheel bolts should be tightened to manufacturer specifications, typically 80-120 Nm for most cars. Hand-tight plus firm wrench pressure usually achieves correct torque.
Can I drive normally on a space-saver wheel?
Space-saver wheels are temporary solutions limited to 50mph maximum speed and 50-mile distance. Replace with a proper tyre immediately.
What if my jack won’t lift the car?
Ensure you’re using the correct jacking point and the jack is positioned vertically. Soft ground may require a solid base under the jack.
How often should I check my spare wheel?
Check spare wheel pressure monthly during routine maintenance. Space-saver wheels lose pressure faster than standard tyres due to their construction.
What tools come with my car?
Most vehicles include a jack, lug wrench, and spare wheel. Location varies by manufacturer – check your owner’s manual for specific details.
Mastering wheel changing techniques ensures you’re never stranded by a puncture. Regular practice in safe conditions builds confidence for real emergencies. Quality tools and properly maintained spare wheels make the process efficient and safe, keeping you mobile when unexpected tyre problems occur.
