What is the bolt pattern on a 1988 Dodge Ram 50?
The bolt pattern for the 1988 Dodge Ram 50 is a 6-lug setup on a 5.5-inch bolt circle (139.7 mm).
Produced as a Dodge-badged version of Mitsubishi’s Mighty Max, the Ram 50 shared its basic underpinnings with other Mitsubishi pickups of its era. That legacy makes the lug count and bolt circle a familiar reference point for wheel swaps and restoration work.
Context and compatibility
During its late-1980s run, Dodge partnered with Mitsubishi to bring a compact pickup to North American buyers. The Ram 50 and the Mitsubishi Mighty Max were essentially siblings, meaning the wheel hub design and bolt pattern were carried over across markets and trims. For this reason, many wheels marketed for the 6x5.5-inch (6x139.7 mm) pattern fit both vehicles from that period, subject to hub bore and offset considerations.
Key compatibility notes
Use this quick reference when assessing wheels or selecting replacements:
- lug count: 6
- bolt circle diameter: 5.5 inches (139.7 mm)
- typical axle sharing: front and rear axles on most 1988 Ram 50 configurations use the same pattern
For restoration or wheel upgrades, always verify exact specs for your vehicle’s market and build date. Some export variants or late- era changes can influence hub bore or specific clearance, even if the lug count and circle diameter remain 6x5.5.
How to verify on your truck
To avoid incorrect wheel purchases, follow these steps to confirm the pattern on your specific Ram 50:
- Count the lug nuts on one wheel to confirm there are six.
- Measure the distance between opposite lug holes to determine the bolt circle diameter (approximately 5.5 inches/139.7 mm).
- Consult the service manual or factory data plate for definitive wheel specifications and hub bore details if you plan on using different wheels.
If shopping for aftermarket wheels, look for 6x5.5-inch compatibility and verify hub bore and offset requirements; hub-centric rings may be needed for proper fitment on some wheel designs.
Summary
The 1988 Dodge Ram 50 uses a 6-lug pattern on a 5.5-inch circle (139.7 mm), a common standard among Mitsubishi-based pickups of that era. This makes many 6x5.5 aftermarket wheels suitable, though always confirm lug count, circle diameter, and hub bore for your specific vehicle and market.
