Looking for the Pontiac G6 wheel bolt pattern before buying new rims? Understanding this critical specification will save you time, money, and frustration when upgrading your vehicle’s wheels.
The Pontiac G6, manufactured between 2005 and 2010, features a consistent bolt pattern across all model years. This mid-size car became popular for its sleek design and performance, but many owners eventually look to customize their ride with aftermarket wheels. Knowing your G6’s exact bolt pattern is essential for ensuring proper fitment and maintaining safety on the road.
Understanding the Pontiac G6 Wheel Bolt Pattern
The Pontiac G6 wheel bolt pattern is 5x110mm, meaning it has 5 lug nuts arranged in a circle with a diameter of 110mm. This specification remains consistent across all G6 models produced between 2005 and 2010. Knowing this pattern is essential when shopping for replacement or aftermarket wheels for your G6.
Wheel bolt patterns consist of two key numbers. The first number (5) indicates how many lug nuts secure the wheel to the hub. The second number (110) represents the diameter in millimeters of the imaginary circle formed by the lug nuts. This measurement is taken from the center of one lug to the center of the lug directly opposite it.
Compatible vehicles sharing the 5x110mm bolt pattern include other GM models like the Chevrolet Malibu, Saturn Aura, and certain Saab vehicles. This compatibility opens up more wheel options for your Pontiac G6. Our customer Liam Kohn recently discovered this when upgrading his G6 GT, finding wheels from a Saturn Aura that perfectly fit his Pontiac.
Additional wheel specifications for your G6 include a center bore of 65.1mm and lug nuts that require a 12×1.5mm thread size. These measurements are just as important as the bolt pattern when ensuring proper wheel fitment. Many G6 owners overlook these details when purchasing new wheels, leading to fitment issues that could compromise safety and performance.
What Is a Wheel Bolt Pattern?
A wheel bolt pattern describes the exact arrangement of lug holes on a wheel, indicating both the number of bolts and their circular positioning. This crucial measurement consists of two numbers (such as 5×115 mm) where the first number represents the count of lug holes, and the second number indicates the diameter of the imaginary circle connecting all lug centers.
How to Measure Bolt Patterns
Measuring your Pontiac G6’s bolt pattern correctly ensures you’ll purchase compatible wheels that fit properly on your vehicle. Different lug configurations require exact measuring techniques:
For the 5-lug pattern found on Pontiac G6 models:
- Measure from the center of one lug hole to the center of the lug hole that’s two positions away (skipping one hole)
- This distance represents the bolt circle diameter (BCD), which is typically 115 mm for G6 models
- Don’t measure between adjacent holes as this won’t give you the accurate bolt circle diameter
For 4-lug wheels on other vehicles:
- Simply measure from the center of one lug hole straight across to the center of the opposite lug hole
- This direct measurement equals your bolt circle diameter
An alternative technique many mechanics prefer involves measuring from the back edge of one lug hole to the center of the third lug hole across the circle. This method often provides more consistent results, especially when working with worn or damaged wheels.
Taking precise measurements is essential because even small discrepancies can create mounting issues, unsafe driving conditions, and potential damage to both your wheels and vehicle components. The Pontiac G6’s 5×115 mm bolt pattern distinguishes it from some other GM vehicles like the Chevrolet Malibu and Saturn Aura that use a 5×110 mm pattern.

The Pontiac G6 maintained a consistent bolt pattern across all model years from 2004 to 2010. This uniformity makes finding compatible wheels more straightforward for G6 owners looking to replace or upgrade their rims.
5x110mm Bolt Pattern Explained
Pontiac G6 vehicles feature a 5x110mm bolt pattern throughout their production run. The first number (5) refers to the number of lug nuts or bolts on each wheel, while the second number (110) indicates the diameter in millimeters of the circle on which these lugs are positioned. This pattern is somewhat less common than the 5×114.3mm configuration found on many other vehicles, making it essential to verify compatibility when shopping for wheels. OEM wheels for the G6 came in various sizes, including 17-inch and 18-inch options, all featuring this exact 5-lug pattern.
Wheel Offset and Hub Bore Considerations
Wheel offset plays a crucial role in proper G6 wheel fitment beyond just the bolt pattern. The offset represents the distance in millimeters from the wheel’s centerline to its mounting surface, affecting how the wheel sits in relation to the vehicle’s body and suspension. Pontiac G6 models typically use a high positive offset, with 2010 models featuring approximately 4.33 inches (110mm) of offset. Selecting wheels with the correct offset prevents potential clearance issues with suspension components or fender wells. The hub bore (center bore) measurement is equally important for proper wheel installation, as it ensures the wheel centers correctly on the hub. Using wheels with an incorrect center bore can lead to vibration and uneven tire wear. When replacing G6 wheels, always verify the bolt pattern, offset, and hub bore specifications together to ensure proper fitment and maintain safe driving characteristics.
