Expert Buying Guide for 1993 Dodge Ram Van B350
For your 1993 Dodge Ram Van B350, the 5x139.7 bolt pattern is shared with 1992–1994 models. The 77.8mm center bore is critical: aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure load is on the hub, not the lugs. Offset is sensitive; stick to 10mm ±10mm to avoid rubbing or clearance issues. Always use the correct lug nuts: 1/2"-20 thread with a conical (60-degree) seat. Never use ball-seat or acorn nuts, as they can loosen. Re-torque after 50 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 135 ft-lbs after 50 miles of driving.
- ✅ If using aftermarket wheels, verify hub bore and use hub-centric rings if bore > 77.8mm.
- ✅ Check offset carefully: too much positive offset can cause inner tire rubbing on suspension components.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

What does 10mm offset mean for the 1993 Ram Van B350?
An offset of 10mm means the wheel's mounting surface is 10mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Dodge.
Why is matching the 77.8mm center bore important for the 1993 Ram Van B350?
The 77.8mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
