Expert Buying Guide for 1998 Nissan Frontier Regular Cab
For your 1998 Nissan Frontier Regular Cab, the bolt pattern is 6x139.7mm with a center bore of 100.1mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibration and ensure proper load distribution.
