Step-by-Step Guide to Changing a Car Tyre
1
1. Prioritize Safety and Prepare the Vehicle
As soon as you notice a flat tyre, slow down and find a safe, level spot away from traffic. Activate your hazard warning lights immediately. Pull over as far as possible from moving vehicles, ideally on a hard, flat surface. Engage the parking brake firmly. If available, place wheel chocks behind the tyres diagonally opposite the one you're changing to prevent the vehicle from rolling. For detailed safety protocols, refer to our guide on roadside tyre change safety.

2. Gather Your Tools and Spare Tyre
Retrieve your spare tyre, car jack, and lug wrench from your vehicle. These are typically stored in the boot or under the vehicle. Ensure you know types of spare tyres and where yours is located. For a complete list of essential items, consult our article on essential car tyre changing tools. If your spare is a 'donut' or temporary spare, remember its limitations.

3. Loosen the Lug Nuts
Before lifting the vehicle, use the lug wrench to loosen the lug nuts on the flat tyre. Turn the wrench counter-clockwise. You may need to use significant force, sometimes even your body weight, to break them loose. Do not remove them completely at this stage; just loosen them about a quarter to half turn until they can be turned by hand.

4. Position the Jack and Lift the Vehicle
Locate the correct jacking point near the flat tyre, usually indicated in your vehicle's owner's manual. It's typically a reinforced metal area on the vehicle's frame. Position the jack securely beneath this point and begin raising the vehicle. Lift it just enough so the flat tyre is entirely off the ground, allowing sufficient space to remove it and install the inflated spare. Avoid placing any part of your body under the vehicle while it's supported only by the jack.

5. Remove the Lug Nuts and Flat Tyre
Once the tyre is clear of the ground, finish unscrewing the lug nuts by hand and place them in a safe, easily accessible spot (e.g., in the hub cap). Carefully pull the flat tyre straight off the wheel studs. It can be heavy, so be prepared to support its weight.

6. Mount the Spare Tyre
Align the spare tyre with the wheel studs and carefully push it onto the hub. Ensure it sits flush against the brake rotor or drum. It's crucial that the spare is properly seated before proceeding.

7. Hand-Tighten the Lug Nuts
Replace the lug nuts, screwing them on by hand as tightly as possible. Start with one lug nut, then tighten the one directly opposite it, then the next, and so on, in a star or criss-cross pattern. This helps ensure the wheel is mounted evenly and prevents warping of the brake rotor.
8
8. Lower the Vehicle and Fully Tighten Lug Nuts
Carefully lower the vehicle until the spare tyre makes contact with the ground but before the full weight of the car is on it. This provides enough resistance to fully tighten the lug nuts. Using the lug wrench, tighten all lug nuts securely in the same star pattern. For specific guidance on the correct tightness, consult our article on lug nut torque specifications. Once fully tightened, lower the vehicle completely and remove the jack.

9. Store the Flat Tyre and Tools
Place the flat tyre in the boot or its designated storage area. Gather all your tools – the jack, lug wrench, and any wheel chocks – and secure them so they don't move around while driving. Ensure nothing is left behind on the roadside.
10
10. Check Spare Tyre Pressure and Drive Cautiously
Before driving, if possible, check the pressure of the newly installed spare tyre. If it's a temporary 'donut' spare, remember it has speed and distance limitations (typically max 50 mph/80 km/h and 50-100 miles). Drive directly to the nearest service station to have the spare tyre pressure checked, and your flat tyre inspected for repair or replacement. Regular checks of your spare are important for preparedness; learn more at spare tyre maintenance check.
Essential Safety Checklist for a Roadside Tyre Change
- Secure a safe, level location away from active traffic.
- Engage the parking brake and place the vehicle in park (automatic) or first/reverse gear (manual).
- Activate hazard warning lights to alert other drivers.
- Place reflective triangles or flares if available, especially at night or in low visibility.
- Wear high-visibility clothing if performing the change at night or in adverse weather.
- Use wheel chocks on the wheel diagonally opposite the flat tyre to prevent rolling.
- Ensure no one is in the vehicle, especially if children are present; have them wait in a safe location away from the roadside.
- Never place any part of your body under a vehicle supported only by a jack.
- Wear sturdy gloves to protect your hands from dirt, grease, and sharp edges.
- Do not over-tighten lug nuts with your body weight; use only the force required to secure them.
Immediate Actions and Important Considerations Post-Tyre Change
After successfully changing your tyre, your immediate next steps are crucial for continued safety. First, drive slowly and cautiously to the nearest service station. It's imperative to have the tyre pressure of your spare checked, as spare tyres often lose pressure over time. Furthermore, the lug nuts should be re-torqued to your vehicle's specific specifications using a torque wrench. Our guide on lug nut torque specifications highlights why this precise tightening is critical for wheel security and preventing damage.
Many spare tyres, especially 'donut' or temporary spares, are designed for limited use. They have strict speed and distance restrictions, typically 80 km/h (50 mph) and a range of 80-160 km (50-100 miles). Exceeding these limits can be dangerous and lead to further tyre damage or loss of vehicle control. Understanding how long to change a car tyre is often less important than understanding how long you can safely drive on the spare.
Lastly, promptly address the flat tyre. Depending on the damage, it might be repairable, or it may require full replacement. A puncture in the tread area can often be patched, but sidewall damage usually necessitates a new tyre. Our article on tyre repair vs replacement provides detailed guidance on this decision. Do not postpone this, as driving without a proper spare or with an unaddressed flat reduces your vehicle's safety margin considerably.
Proactive Tyre Maintenance: Preventing Flats and Enhancing Readiness
While knowing how to change a tyre is essential, preventing flats in the first place can save you significant time and hassle. Regular tyre maintenance is your best defence. This includes routinely checking your tyre pressure, as under-inflated or over-inflated tyres are more susceptible to punctures and blowouts. Visually inspect your tyres for signs of wear, such as shallow tread depth, cracks, bulges, or embedded objects. Rotating your tyres regularly, as recommended by your vehicle manufacturer, also helps ensure even wear and prolongs tyre life. Learn more about proactive measures in our guide on preventing flat tyres.
Understanding your vehicle's tyre type is also key to preparedness. Some modern vehicles come equipped with what are run-flat tyres, which allow you to drive for a limited distance after a puncture, eliminating the immediate need for a roadside tyre change. While convenient, run-flats require specialized handling and may not be repairable after a puncture. Always refer to your car's manual and tyre manufacturer guidelines for specific instructions.
Beyond tyre care, assembling an emergency kit can significantly enhance your readiness. This kit should include items like a robust flashlight with extra batteries, work gloves, a reflective safety vest, and perhaps even a small piece of wood to place under the jack for stability on soft ground. For comprehensive information on tyre safety and maintenance, the National Highway Traffic Safety Administration (NHTSA) offers valuable resources. Being prepared means you're not just reacting to a flat but are equipped to manage it confidently and safely.
