The 2004 Pontiac Grand Prix features a specific bolt pattern that is essential for selecting compatible wheels. Understanding this specification is crucial for vehicle owners looking to upgrade or replace their rims.

Bolt Pattern Details

The bolt pattern for the 2004 Pontiac Grand Prix is:

  • 5 lug
  • 115 mm diameter (also known as 5x115)

This means that there are five bolt holes arranged in a circle with a diameter of 115 mm.

Compatibility with Other Wheels

While the factory specification is 5x115, some users have successfully mounted wheels with a bolt pattern of 5x114.3. However, using wheels with this slightly different measurement may lead to issues such as vibration or wobbling unless hub-centric rings are used to ensure proper fitment.

Here are some points to consider:

  • Hub Bore Size: Ensure the hub bore of the new wheels matches the Grand Prix's specifications for optimal fit.
  • Stress on Studs: Using wheels with a different bolt pattern can potentially stress the wheel studs, especially under aggressive driving conditions.

Wheel Specifications

For the 2004 Pontiac Grand Prix, the typical wheel specifications include:

  • Width: 6.5 inches
  • Offset: High positive offset (specific values can vary depending on the wheel design)
  • Material: Often aluminum alloy for OEM wheels

These specifications help determine the overall performance and handling characteristics of the vehicle when different wheels are installed.
