Expert Buying Guide for 2018 Cadillac CTS
For your 2018 Cadillac CTS, the bolt pattern is 5x120.65 with a center bore of 67.1mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibrations and ensure proper load distribution. The factory offset is 24mm; deviations beyond ±5mm may cause clearance issues with suspension or bodywork. Always verify lug nut thread pitch (14x1.50) and seat type—factory uses conical (60-degree) seats. Using incorrect lug nuts can lead to wheel loosening. Cross-compatible wheels from 2009–2019 CTS models fit, but avoid 5x115 pattern wheels from earlier years.
