Pontiac Wheel Bolt Pattern by Model
What This Guide Covers
This guide identifies wheel bolt patterns for popular Pontiac models, including the G6, Solstice, G8, Fiero and Vibe. Bolt pattern is expressed as the number of wheel studs followed by the diameter of the circle they form, for example 5x110. Where a specification changes by generation, trim, or market, that qualification is stated.
Pontiac G6 Wheel Bolt Pattern
The Pontiac G6 uses a 5x110 bolt pattern for all model years sold in North America. The center bore is 65.1 millimeters. This applies to sedan, coupe and retractable hardtop convertible body styles with stock four-cylinder and V6 powertrains. A 5x110 pattern means the wheel has five studs arranged on a 110-millimeter bolt circle. Because this is a less common pattern than 5x114.3, aftermarket wheel selection is more limited, and hub-centric rings or conversion considerations are sometimes discussed by owners researching wheel fitment.
Pontiac Solstice Wheel Bolt Pattern
The Pontiac Solstice uses a 5x110 bolt pattern for model years sold in North America. The center bore is 65.1 millimeters. This specification covers both the naturally aspirated and GXP turbocharged versions. The shared 5x110 measurement with the G6 reflects common platform hardware rather than an identical wheel design, so offset and width requirements still differ between the two models.
Pontiac G8 Wheel Bolt Pattern
The Pontiac G8 uses a 5x120 bolt pattern for all trim levels sold in North America, including the base V6, GT and GXP V8 variants. The documented center bore is 66.9 millimeters. The 5x120 measurement is widely used by other rear-wheel-drive platforms, which gives G8 owners a large selection of factory and aftermarket wheels. Any wheel chosen for the G8 still needs to match the factory offset range and hub bore to avoid clearance or vibration issues.
Pontiac Fiero Wheel Bolt Pattern
The Pontiac Fiero uses a 5x100 bolt pattern for all model years spanning the 1984 through 1988 production run. The center bore is 57.1 millimeters. This applies to the four-cylinder and V6 engines as well as base, SE and GT trims. Because the Fiero is a mid-engine car with specific front and rear offset requirements, wheels with the correct 5x100 pattern may still require careful measurement before fitment.
Pontiac Vibe Wheel Bolt Pattern
The Pontiac Vibe uses a 5x100 bolt pattern for the first and second generations sold in North America. The documented center bore is 54.1 millimeters. This applies to front-wheel-drive and all-wheel-drive versions, including the base, AWD and GT trims. The Vibe shares its platform hardware with the Toyota Matrix, but wheel specifications should still be confirmed for the specific year and trim because offset can vary.
Summary Table of Common Pontiac Bolt Patterns
Model | Bolt Pattern | Center Bore (approx.); Pontiac G6 | 5x110 | 65.1 mm; Pontiac Solstice | 5x110 | 65.1 mm; Pontiac G8 | 5x120 | 66.9 mm; Pontiac Fiero | 5x100 | 57.1 mm; Pontiac Vibe | 5x100 | 54.1 mm
Other Pontiac Models and Important Notes
Several other Pontiac models share patterns with similar General Motors vehicles. The Grand Prix, Grand Am, Bonneville and Aztek generally use 5x115 for many model years, while the Sunfire generally uses 5x100. Material gaps exist for less common or export-market configurations, so this guide does not extend a single pattern to every Pontiac model without a year and platform qualifier.
Before purchasing wheels, confirm the complete fitment specification for the exact model year and trim. That includes bolt pattern, center bore, wheel diameter, width and offset. A matching bolt pattern alone does not guarantee proper clearance or load rating. If a specification is not documented for a particular variant, treat it as uncertain rather than assuming it matches a similar model.
