If your car starts to wobble during a tire change, it’s crucial to prioritize safety and address the issue immediately. A wobbling car can indicate instability, which poses a risk of the vehicle falling off the jack or stands. Here’s what you should do to ensure safety and successfully complete the tire change.
Why Does a Car Wobble During a Tire Change?
Understanding why your car might wobble is the first step to addressing the problem. Several factors can contribute to this issue:
- Improper Jack Placement: The jack may not be positioned correctly under the vehicle’s jacking point.
- Unstable Surface: The ground may be uneven or soft, leading to instability.
- Faulty Equipment: A damaged or low-quality jack or stands might not support the car properly.
- Vehicle Movement: The car may not be in park (automatic) or in gear (manual), or the parking brake might not be engaged.
How to Safely Address a Wobbling Car
- Stop Immediately: If you notice any wobbling, stop what you’re doing to prevent the car from falling.
- Check Jack Placement: Ensure the jack is correctly positioned under the designated jacking point.
- Inspect the Surface: Make sure the ground is solid, flat, and stable. Use a piece of plywood under the jack if necessary.
- Engage the Parking Brake: Ensure the parking brake is fully engaged and the vehicle is in the correct gear.
- Use Wheel Chocks: Place chocks behind the wheels on the ground to prevent any movement.
Practical Steps to Prevent Car Wobbling
How to Properly Use a Car Jack and Stands?
- Select the Right Equipment: Use a jack and stands rated for your vehicle’s weight.

- Test Stability: Gently rock the car to ensure it’s stable before proceeding with the tire change.
What to Do If the Car Is on an Uneven Surface?
