Expert Buying Guide for 1994 Dodge Ram Van B350
For your 1994 Dodge Ram Van B350, the 5x139.7 bolt pattern and 77.8mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 78.1mm or 108mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The offset is sensitive: stick to a 10mm range (0 to 20mm) to avoid rubbing or clearance issues. Always use the correct lug nuts: 1/2"-20 thread with a conical (60-degree) or ball seat—never use acorn or flat-seat nuts. Improper seating can cause wheel loss. Re-torque after 50-100 miles.
