2011 Buick Lucerne Wheel Interchange
tl;dr
2011 Buick Lucerne stock wheels are 17x7.0 ET46, 5x115 PCD, center bore 70.3mm, M12x1.5 lugs. Use the on-page calculator to test alternate wheel sizes and offsets before buying. Confirm any missing fit details with OEM dealer literature or your vehicle’s VIN.
Recommendation
Start by matching bolt pattern, center bore, and thread size exactly.
Use wheels that keep effective offset within about +/- 10mm of ET46.
Choose tires sized near 235/55R17 to preserve speedometer and clearance.
Impact
| Spec | OEM value |
|---|---|
| Bolt pattern | 5x115 |
| Center bore | 70.3 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 17 in |
| Rim width | 7.0 in |
| Wheel offset (ET) | 46 mm |
| Backspacing | 5.31 in |
| Tire (stock) | 235/55R17 |
Staying close to OEM numbers preserves handling, ABS calibration, and fender clearance.
Risks
- Wrong bolt pattern risks stud damage and wheel loss.
- Incorrect center bore can cause wobble unless hub-centric rings used.
- Wrong thread size will prevent proper lug tightening.
- Large offset shifts can rub suspension or fenders during compression.
- Oversized tires affect speedometer, fuel economy, and ABS/VSC function.
Some details may vary by trim or aftermarket parts. Don’t assume universal fit.
Next actions
Checklist for a safe wheel change:
- Confirm VIN-specific specs with dealer or owner’s manual.
- Use the on-page wheel/tire calculator to simulate changes.
- Match bolt pattern 5x115 and thread M12x1.5 exactly.
- Fit hub-centric rings if center bore larger than 70.3 mm.
- Select lug nuts with correct seat type; verify seat shape first.
- Torque lugs to the OEM spec from factory literature or dealer.
- Check for brake caliper and suspension clearance after test fit.
Gotchas: lug seat shape and torque spec are often omitted online. Confirm both.
How to use the on-page calculator
Enter the donor wheel and your custom wheel sizes. Observe diameter and scrub changes. Adjust offset until hypothetical fit shows no rubbing. The calculator updates tire diameter when you change rim diameter.
Where to buy common parts
Tools and small parts to have ready:
next steps: run the calculator scenarios you need, confirm any missing OEM values, then order wheels and parts. When installing, follow a cross-torque pattern and recheck torque after 50–100 miles. This closes the loop on fitment and safety.
