Expert Buying Guide for 1998 Chevrolet 2500 Regular Cab
For your 1998 Chevrolet 2500 Regular Cab, the 8x165.1 bolt pattern is shared with 1992-1998 models. The 116.7mm center bore requires hub-centric rings for aftermarket wheels to prevent vibration and hub damage. Offset is critical: stock is 20mm; deviations affect scrub radius and tire clearance. Always use 14x1.5 lug nuts with the correct seat (cone or ball) matching the wheel. Mismatched seats cause loosening and wheel loss. Re-torque after 50-100 miles. Avoid wheels with insufficient load rating for this heavy-duty truck.
