These are vehicle-year records whose recorded OEM ranges overlap this 2017 Buick LaCrosse. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 65 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Approximate position vs the mid OEM package: outer change -2.18 mm, inner change -4.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Recorded vehicle-side thread for the 2017 Buick LaCrosse is M12x1.5. This donor year is recorded as M14x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

Recorded vehicle-side thread differs (M14x1.5 on the donor year vs M12x1.5 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset. Approximate position vs the mid OEM package: outer change 4.18 mm, inner change 2.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionWheel spacer ≈ 10.18 mm – not a verified installation requirement.
A spacer of about 10.18 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 10.18 mm farther inward than the mid OEM package.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.

Recorded vehicle-side thread for the 2017 Buick LaCrosse is M12x1.5. This donor year is recorded as 1/2"-20UNF. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

The values below are confirmed items we have for the 2017 Buick LaCrosse. Trims and option packages can change wheel and tire specs. If a value is not listed, verify it on your door-jamb tire label, owner’s manual, or with the on-page calculator and an OEM source before you buy.
| Spec | Known value | Notes |
|---|---|---|
| Bolt pattern | 5x115 | 5 studs on a 115 mm circle |
| Center bore | 70.3 mm | Use hub-centric wheels or rings that reduce to 70.3 mm |
| Thread size | M12 x 1.5 | Confirm lug seat type for your wheel before purchase |
| Wheel diameter | 19 in | Known OEM wheel option |
| Wheel width | 8.5 in | Known OEM wheel option |
| Wheel offset | ET 40 mm | Known OEM wheel option |
| Backspacing | 5.82 in | Corresponds to 19x8.5 ET40 |
| Tire size | 235/50R18 | Known OEM tire option; other trims may differ |
Important: The LaCrosse was offered with multiple wheel and tire packages. If your car shows a different OEM size on the door sticker or in the manual, use those as your baseline and compare with the calculator before selecting wheels.
The LaCrosse was offered with different OEM packages. Some owners move between 18-inch and 19-inch setups to tune ride and handling. If you plan to change sizes:
If your LaCrosse currently has 235/50R18 and you are considering a 19-inch wheel, compare the new tire’s diameter and width to your OEM baseline and inspect clearances at full lock and over bumps.
Can I use 5x114.3 wheels on a 5x115 Buick LaCrosse?
It is not recommended. The mismatch can stress studs and compromise safety. Use the exact 5x115 pattern.
Do I need hub-centric rings on aftermarket wheels?
If the wheel’s center bore is larger than 70.3 mm, use rings that reduce the bore to 70.3 mm for a hub-centric fit and minimized vibration.
What offset should I choose?
Start with the OEM reference. For a known OEM 19x8.5, ET40 is typical. Keep your new offset close and verify inner and outer clearance with the calculator and a physical test fit.
What tire size can I run without rubbing?
Clearance depends on tire width, overall diameter, wheel width, and offset. Use the calculator to compare against your OEM tire and inspect at full steering lock and over suspension travel. When uncertain, measure and consult service data.
Will changing wheel size affect my speedometer?
Only if the overall tire diameter changes. Keep the new tire’s overall diameter close to OEM to minimize speedometer error. The calculator will show the difference.
Do I need new lug nuts?
Possibly. You must match thread size M12x1.5 and the seat type required by your new wheels. Never mix seat styles.
How do I confirm my car’s original size?
Check the tire label on the driver’s door jamb and the owner’s manual. Use those values as your baseline in the calculator.
If any spec for your exact trim is not listed here, verify it with the calculator, your door-jamb label, the owner’s manual, or an OEM service source before purchasing wheels or tires.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
