Changing a tire is a crucial skill for any driver, and using a jack properly is a big part of that process. Here’s a step-by-step guide to ensure you can safely and effectively use a jack when changing a tire.
How to Use a Jack Safely When Changing a Tire
To use a jack properly when changing a tire, first ensure your vehicle is on a flat, stable surface. Secure the vehicle with the parking brake and place wheel wedges under the opposite tires. Locate the jacking point closest to the flat tire, position the jack, and raise the vehicle until the tire is off the ground. Replace the tire, lower the vehicle, and tighten the lug nuts.
What Tools Do You Need to Change a Tire?
Before you start, make sure you have the right tools:
- Jack: A hydraulic or scissor jack suitable for your vehicle.
- Spare tire: Fully inflated and in good condition.
- Lug wrench: To loosen and tighten the lug nuts.
- Wheel wedges: To prevent the vehicle from rolling.
- Gloves and flashlight: For safety and visibility, especially at night.
Where to Position the Jack?
Positioning the jack correctly is crucial for safety. Follow these steps:
- Identify the Jacking Points: Consult your vehicle’s manual to find the recommended jacking points. Typically, these are reinforced areas near each wheel.
- Place the Jack: Align the jack under the jacking point closest to the flat tire. Ensure it’s stable and perpendicular to the ground.
How to Properly Lift the Vehicle?
Once the jack is positioned, follow these steps to lift the vehicle:
- Loosen Lug Nuts: Before lifting, slightly loosen the lug nuts with the lug wrench. Do not remove them completely.
- Raise the Vehicle: Use the jack handle to lift the vehicle until the tire is about 6 inches off the ground. Ensure the jack remains stable throughout the process.
- Remove the Tire: Fully remove the loosened lug nuts and take off the flat tire.
How to Install the Spare Tire?
With the vehicle lifted, you can install the spare tire:
- Align the Spare Tire: Place the spare on the hub, aligning the holes with the lug bolts.
- Hand-Tighten Lug Nuts: Start threading the lug nuts by hand to ensure they don’t cross-thread.
- Tighten with Lug Wrench: Use the wrench to snug the lug nuts in a crisscross pattern.
How to Lower the Vehicle Safely?
Once the spare tire is secure, lower the vehicle:
- Lower the Jack: Slowly turn the jack handle to lower the vehicle until the tire touches the ground.
- Tighten Lug Nuts: Fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
- Remove the Jack: Once tightened, remove the jack and store it properly.
Safety Tips for Using a Jack
- Never work under a vehicle supported only by a jack. Use jack stands if you need to work under the car.
- Check the jack’s condition before use, ensuring it’s free of rust or damage.
- Avoid using a jack on uneven or soft surfaces. This can cause instability and potential accidents.

What Type of Jack Should I Use?
The type of jack you should use depends on your vehicle. Scissor jacks are compact and often come with the car, while hydraulic jacks provide more stability and are easier to use. Always choose a jack that matches your vehicle’s weight capacity.
How Often Should I Check My Spare Tire?
Check your spare tire’s pressure and condition every six months. A flat spare is useless in an emergency, so ensure it’s properly inflated and free of damage.
Can I Change a Tire Without a Jack?
While it’s technically possible to change a tire without a jack, it’s unsafe and not recommended. A jack provides the necessary lift to safely remove and replace a tire.
Why Is It Important to Tighten Lug Nuts in a Crisscross Pattern?
Tightening lug nuts in a crisscross pattern ensures even pressure distribution across the wheel, preventing warping and ensuring the wheel is securely attached.
What Should I Do If My Jack Fails?
If your jack fails, do not attempt to repair it while under load. Secure the vehicle with wheel wedges, and seek professional assistance or use a backup jack if available.
