What is the bolt pattern on a first generation Dodge?
Most first-generation Dodge passenger cars use a 5-lug pattern on a 4.5-inch bolt circle (114.3 mm). However, there were variations by model and year, especially among trucks and heavier-duty variants. The bolt pattern is defined by the number of lug holes and the diameter of the circle they lie on, and getting it right matters for wheel compatibility and safety.
Understanding bolt patterns
A bolt pattern (also called a lug pattern) specifies how many lug holes a wheel hub has and the diameter of the circle that passes through the centers of those holes. The two most important numbers are the lug count (how many bolts) and the bolt circle diameter (BCD). For most classic Mopar vehicles from the first generation, these figures determine which wheels will mount correctly and safely.
Common bolt patterns in first-generation Dodges
Across the era, two patterns appear most often for Dodge vehicles—from passenger cars to trucks. The list below highlights the patterns you’re most likely to encounter.
- 5 x 4.5 inches (114.3 mm) — The most common pattern on Dodge passenger cars of the 1960s and 1970s.
- 5 x 5 inches (127 mm) — Used on some Dodge trucks and heavier-duty applications in the same general period.
Note: There were exceptions depending on the exact model and year. Always verify with the owner's manual, a factory parts diagram, or a trusted parts supplier for your specific vehicle.
How to confirm your vehicle's bolt pattern
To confirm the exact bolt pattern on your specific vehicle, use these steps:
- Count the lug holes on the wheel hub to confirm lug count (most first-generation Dodges use five).
- Measure the bolt circle diameter by drawing or imagining a line through the centers of two opposite lug holes. For common patterns of this era, you should see about 4.5 inches (114.3 mm) or 5 inches (127 mm).
- Consult the owner's manual, a factory service diagram, or a reputable parts catalog to confirm the exact bolt pattern for your model-year.
Pro tip: When swapping wheels, also check center bore size and offset to ensure proper fit and clearance.
Practical considerations for wheel swaps
Beyond the bolt pattern, ensure center bore compatibility, correct offset, appropriate wheel width, and load rating. If in doubt, consult a dealer or use a wheel compatibility database with your VIN to avoid clearance issues or safety risks.
Summary
In short, the most common bolt pattern on first-generation Dodge passenger cars is 5x4.5 inches (114.3 mm), with 5x5 inches (127 mm) appearing on some trucks and heavy-duty models. Always verify for your specific vehicle by checking manuals, diagrams, or consulting a professional before purchasing wheels or adapters.
