Expert Buying Guide for 2009 Acura TSX
For your 2009 Acura TSX, the correct bolt pattern is 5x114.3 with a center bore of 64.1mm. When installing aftermarket wheels, always use hub-centric rings to ensure the wheel is centered on the hub, preventing vibrations. The factory offset is 45mm; staying within ±5mm is recommended to avoid rubbing or clearance issues. Lug nuts must be 12x1.5 thread pitch with a conical (60-degree) seat—never use ball-seat or acorn nuts. Improper lug nut seating can lead to wheel loss. Always torque to 80 ft-lbs and re-torque after 50 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80 ft-lbs after 50 miles of driving to ensure proper seating.
- ✅ Avoid using wheels with a center bore larger than 64.1mm without hub-centric rings to prevent vibration.
- ✅ Check inner clearance for wheels with offset below 40mm, as they may rub on suspension components.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ Confirm bolt pattern carefully. 5x114.3 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
