2022 Buick Encore Wheel Interchange
Tl;dr
2022 Buick Encore uses 5x105 bolt pattern, M12 x 1.5 threads, and a 56.6 mm center bore. Wheels listed as 16x6.5 with ET38 and 4.75 in backspacing. Tire specs show 215/55 but the rim diameter is inconsistent on your sheet. Use the on-page calculator to compare sizes and confirm rim diameter before buying wheels or tires.
Recommendation
As a technician, I recommend a quick confirm and a checklist approach. First verify the actual rim diameter on your vehicle. Then match bolt pattern, thread pitch, and center bore exactly. Use hub-centric rings if wheel bore exceeds 56.6 mm. Choose lug nuts rated for M12 x 1.5 threads and the wheel material. Finally, run the on-page wheel/tire calculator to validate clearance, speedometer error, and rubbing risk.
Impact
Correct fitment preserves handling, braking, and wheel bearing life. Matching offset and backspacing keeps scrub radius and steering feel near OEM. Incorrect center bore or lug type can cause vibration or stripped threads. Tire diameter changes affect speedometer, gearing, and ABS function.
Risks
Here are the key gotchas I see for the Encore lifecycle.
- Rim diameter mismatch. Your sheet lists 16 inch wheels but tires reference 18 inch. Confirm which is correct.
- Using wheels with too-small center bore risks hub-centric misalignment. Use rings if needed.
- Wrong lug nuts or stud engagement can strip threads or loosen wheels.
- Large tire diameter increases speedometer error and may trigger ABS traction warnings.
- Staggered widths or extreme offsets can cause rubbing and suspension interference.
Known OEM fitment (from provided data)
| Spec | Value |
|---|---|
| Bolt pattern | 5x105 |
| Center bore | 56.6 mm |
| Thread size | M12 x 1.5 |
| Wheel rim diameter | 16 in |
| Wheel rim width | 6.5 in |
| Offset (ET) | 38 mm |
| Backspacing | 4.75 in (≈120.7 mm) |
| Tire section width | 215 mm |
| Tire aspect ratio | 55 |
| Tire rim diameter | 18 in (conflict – confirm) |
Note: Backspacing and offset are consistent for the listed wheel width. I calculated backspacing 4.75 in equals about 120.7 mm. Subtracting half the rim width (3.25 in ≈ 82.6 mm) gives ≈38.1 mm offset. That matches ET38 in your data.
Next actions
Follow this minimal checklist to finish fitment safely.
- Physically measure your vehicle wheel diameter. Check tire sidewall or wheel stamp. If either lists 18, your sheet is inconsistent.
- Open the on-page calculator. Compare donor wheel versus installed wheel. Adjust rim diameter, width, and offset until dimensions align.
- Confirm lug torque in the owner manual or dealer documents. Don’t rely on guesswork for torque values.
- If aftermarket wheels have a larger bore, buy hub-centric rings sized to 56.6 mm. Check ring specs match wheel and hub precisely.
- Buy lug nuts rated for M12 x 1.5 with the correct seat type for your wheel (tapered or mag).
- Test-fit one wheel and roll the vehicle to check clearance before final torque.
Checklist for buying: verify rim diameter, bolt pattern, center bore, thread size, and offset. Use the calculator and OEM sources when in doubt.

Next steps: confirm your rim diameter, then use the on-page calculator to finalize sizes. If any specification varies by trim, check the owner manual or dealer documents. That completes the immediate checklist and resolves fitment risk.
