Expert Buying Guide for 2007 MAZDA B-Series Extended Cab
For your 2007 MAZDA B-Series Extended Cab, the bolt pattern is 6x139.7mm with a center bore of 93.1mm. When selecting aftermarket wheels, ensure they have a center bore of at least 93.1mm or use hub-centric rings to prevent vibration and ensure proper load distribution. The factory offset is 25mm; deviations beyond ±10mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.50) and seat type—factory wheels use a conical (60-degree) seat. Avoid ball-seat lug nuts as they can loosen. Re-torque lug nuts after 50-100 miles of driving. Note: 2008+ models use 5x114.3; those wheels will not fit.
