Expert Buying Guide for 1998 Ford F250 Regular Cab
For your 1998 Ford F250 Regular Cab, the bolt pattern is 8x165.1mm with a center bore of 124.9mm. Aftermarket wheels often have a larger bore, so hub-centric rings (124.9mm ID to 74.1mm or other) are essential to prevent vibration and ensure proper load distribution. The factory offset is 0mm; deviations beyond ±12mm may cause rubbing or clearance issues. Always use the correct lug nuts: 9/16-18 thread with a conical (60-degree) seat. Never use ball-seat lug nuts, as they can loosen. Re-torque after 50-100 miles of driving. Note: 1999+ F250 wheels (8x170) will not fit. Stick to 1992-1998 F250 wheels for direct compatibility.
