Changing a tyre requires a spare tyre, lug wrench, jack, and wheel wedges. The process involves loosening the wheel bolts, raising the vehicle, removing the flat tyre, fitting the spare, and lowering the car. This essential skill ensures you’re never stranded with a puncture.
Tools and parts required
Before starting any tyre change, gather all necessary equipment. Having everything ready prevents delays and ensures safety during the procedure.
Parts needed:
- Spare tyre (properly inflated)
- Valve caps
- Wheel bolts (if replacements needed)
Tools required:
- Lug wrench (cross-brace or telescopic)
- Car jack (scissor, trolley, or bottle type)
- Wheel wedges or chocks
- Warning triangle or hazard lights
- Gloves (optional but recommended)
- Tyre pressure gauge
- Torch (for low-light conditions)
Safety precautions
Safety must be your priority when changing a tyre. Park on level, solid ground away from traffic. Apply the handbrake and engage first gear (manual) or park position (automatic). Turn on hazard warning lights and place a warning triangle 45 metres behind your vehicle on roads, or 150 metres on motorways.
Never change a tyre on the hard shoulder of a motorway unless absolutely necessary. Instead, use emergency phones to call for assistance. Ensure passengers exit the vehicle and stand well clear of the road.

Step-by-step instructions
Step 1: Secure the vehicle
Position wheel wedges behind the tyres opposite to the flat tyre. If changing a front tyre, place wedges behind rear wheels. For rear tyre changes, position wedges in front of front wheels. This prevents the vehicle rolling during the change process.
Remove the spare tyre and tools from your boot. Check the spare tyre pressure if possible – it should match the recommended pressure for your vehicle.
Step 2: Loosen wheel bolts
Remove the wheel trim or hubcap if fitted. Locate the correct socket size on your lug wrench. Position the wrench on each wheel bolt and turn anticlockwise to loosen them. Only loosen the bolts at this stage – don’t remove them completely whilst the wheel is still on the ground.
Apply steady pressure rather than sudden jerking movements. The bolts may be tight, so use your body weight if necessary. Loosen all bolts by approximately half a turn each.
Step 3: Raise the vehicle
Locate the correct jacking point for your vehicle. This information is in your owner’s manual and usually marked on the vehicle’s sill. Position the jack securely and ensure it’s perpendicular to the ground.
Raise the vehicle until the flat tyre is approximately 15cm off the ground. The wheel should spin freely without touching the surface. Never place any part of your body under a raised vehicle supported only by a jack.
Step 4: Remove the flat tyre
Now completely remove the loosened wheel bolts. Keep them safe in a container or your pocket. Pull the tyre straight towards you to remove it from the wheel hub. Flat tyres can be heavy, so maintain a firm grip and bend your knees when lifting.
Place the flat tyre flat on the ground beside your vehicle, away from the traffic side.
Step 5: Install the spare tyre
Align the spare tyre with the wheel bolts on the hub. Push the wheel firmly onto the hub until it sits flush. Replace the wheel bolts and hand-tighten them initially.
Using the lug wrench, tighten the bolts in a star pattern (opposite bolts) rather than working around the wheel sequentially. This ensures even pressure distribution and proper wheel seating.
Step 6: Lower the vehicle and final tightening
Lower the jack until the spare tyre just touches the ground but still supports some vehicle weight. Complete the final tightening of wheel bolts using the star pattern. Apply firm pressure to ensure bolts are properly secured.
Lower the vehicle completely and remove the jack. Give the wheel bolts a final check to ensure they’re tight. Replace any wheel trim or hubcap if applicable.

Common mistakes to avoid
Many drivers make critical errors during tyre changes that compromise safety. Never attempt to change a tyre without proper wheel wedges – vehicles can roll unexpectedly, causing serious injury.
Avoid loosening wheel bolts after raising the vehicle. The wheel will spin freely, making bolt removal extremely difficult. Always loosen bolts whilst the tyre remains on the ground.
Don’t overtighten wheel bolts, as this can damage threads or warp brake components. Equally, under-tightening allows wheels to work loose whilst driving. Use consistent, firm pressure when tightening.
Never use the jack on soft ground without a solid base plate. Jacks can sink into soft surfaces, causing the vehicle to fall. Similarly, ensure the jack contacts the designated jacking point to prevent structural damage.
Avoid changing tyres on busy roads when possible. Even with hazard lights and warning triangles, roadside changes present significant risks from passing traffic.
When should you replace your spare tyre?
Spare tyres require regular inspection and maintenance like standard tyres. Check spare tyre pressure monthly – underinflated spares can fail when you need them most. Most spare tyres lose pressure naturally over time.
Space-saver spare tyres typically last 3-5 years regardless of mileage. Full-size spares follow normal tyre replacement intervals based on tread depth and age. Replace any spare showing cracks, bulges, or excessive wear.
Temporary spare tyres (space-savers) have speed restrictions, usually 50mph maximum. They’re designed for short distances only – typically 50 miles maximum. Plan to replace or repair your main tyre promptly after fitting a space-saver spare.
Consider the age of your spare tyre. Rubber degrades over time, even without use. Tyres over six years old should be professionally inspected, regardless of apparent condition.
Related maintenance you can do at the same time
Tyre changes provide excellent opportunities for additional vehicle checks. Inspect brake pads through wheel spokes whilst the wheel is off. Look for excessive wear, scoring, or contamination.
Check brake disc condition for scoring, rust, or uneven wear patterns. Examine suspension components for leaks, damage, or excessive wear. Look at shock absorber condition and suspension arm bushings.
Inspect wheel wells for damage, rust, or debris accumulation. Clean any mud or salt deposits that could cause corrosion. Check brake lines and ABS sensor cables for damage or wear.
Consider rotating your tyres if changing due to wear rather than puncture. This promotes even tyre wear and extends overall tyre life. Many drivers overlook this simple maintenance task that significantly impacts tyre longevity.
Use this opportunity to check tyre pressure on all wheels using a reliable gauge. Proper inflation improves fuel economy, handling, and tyre life whilst reducing the risk of future punctures.
Frequently asked questions
Most experienced drivers complete a tyre change in 15-30 minutes. First-time changes may take 45 minutes including tool familiarisation and safety preparations.
Space-saver spares limit speed to 50mph maximum and distance to approximately 50 miles. They’re temporary solutions requiring immediate replacement.
Apply penetrating oil and wait several minutes. Use your body weight on the lug wrench, ensuring anticlockwise rotation. Call professional assistance if bolts remain stuck.
Avoid changing tyres in heavy rain when possible. If necessary, work slowly, ensure secure footing, and increase following distance when driving afterwards.
Always replace valve caps to prevent dirt contamination and slow air leaks. Check caps are properly tightened but avoid overtightening plastic caps.
Learning to change tyres confidently transforms punctures from emergencies into minor inconveniences. Practice these techniques in safe environments before facing roadside situations. Keep your spare tyre properly maintained and ensure all tools remain in your vehicle. With proper preparation and technique, you’ll handle tyre changes safely and efficiently, maintaining your independence on the road.
