Expert Buying Guide for 2018 Buick Cascada
For your 2018 Buick Cascada, the bolt pattern is 5x115 with a critical center bore of 70.2mm. Aftermarket wheels often have a larger bore, so hub-centric rings are mandatory to prevent vibration and ensure proper load distribution. The offset range is 35-45mm; deviating can cause rubbing or clearance issues. Always use M12x1.5 lug nuts with the correct seat type—factory wheels use a conical (60-degree) seat. Never use ball-seat or shank-style nuts. Re-torque after 50-100 miles to maintain clamping force. Wheels from 2016-2019 Cascada models are direct fit.

Quick Tips & Safety Warnings

- ✅ Lug nut torque: 100 ft-lbs; re-torque after 50-100 miles and check periodically.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
