Wheel Nut Sizes & Safe Jacking: What Every Melbourne Driver Should Know Before Working on Their Wheels

Whether you're upgrading your wheels, painting your calipers, or performing basic maintenance, understanding wheel nut sizes and how to safely raise your vehicle is essential.

For drivers searching for brake caliper painting in Melbourne or considering DIY work before booking a brake caliper painting service, safety and preparation should always come first.

This guide breaks down everything you need to know.

Understanding Wheel Nut (Lug) Sizes

Wheel nuts, also known as lug nuts, are what secure your wheels to the vehicle hub. While they may look similar across cars, the size and specifications can vary significantly.

Common Wheel Nut Sizes

Most vehicles use standard hex sizes such as:

• 17mm
• 19mm
• 21mm
• 22mm

However, size alone isn't the full story. You also need to consider:

• Thread size and pitch (e.g. M12x1.5, M14x1.25)
• Seat type (cone, ball, or flat)
• Torque specifications (critical for safety)

Using the wrong size or incorrect seating type can:

• Damage the wheel
• Cause improper tightening
• Lead to wheel vibration or loosening

Pro Tip

Always loosen your wheel nuts before lifting the vehicle. This prevents the wheel from spinning and reduces stress on the jack—something even experienced mechanics follow as standard practice.

How to Safely Jack Up Your Vehicle

Lifting a vehicle is where things can go seriously wrong if done incorrectly. In Australia, injuries and fatalities still occur each year due to improper jack use.

Here's the safest method based on best-practice guidelines.

Step-by-Step: Safe Jacking Procedure

1. Choose the Right Surface

Always work on a flat, hard surface such as concrete.

Soft ground (like grass or gravel) is unsafe because the jack can shift or sink.

2. Secure the Vehicle

Before lifting:

• Put the car in park (or in gear for manual)
• Engage the handbrake
• Use wheel chocks on the opposite wheels

This prevents any movement while lifting.

3. Locate Correct Jacking Points

Every vehicle has designated lifting points—usually along the pinch welds or chassis.

Always check your owner's manual. Lifting from the wrong spot can:

• Damage the car
• Cause the jack to slip
• Lead to serious injury

4. Lift the Vehicle Slowly

Position the jack correctly and raise the car slowly until the wheel is just off the ground.

Make sure:

• The jack is rated for your vehicle's weight
• It is stable and vertical

5. ALWAYS Use Jack Stands

This is the most important rule.

Never get under a vehicle supported only by a jack.

Once lifted:

• Place jack stands under solid support points
• Slowly lower the car onto the stands
• Give the car a gentle shake to confirm stability

Jack stands are designed to hold weight safely—jacks are not.

6. Extra Safety Measures

Professional workshops and experienced DIYers often:

• Leave the jack lightly engaged as backup
• Place a removed wheel under the car as a fail-safe
• Keep clear of the vehicle until stability is confirmed

These small steps can make a big difference.
