Recorded OEM specifications for the 2008 Buick LaCrosse, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.

These are vehicle-year records whose recorded OEM ranges overlap this 2008 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.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -3.18 mm, inner change -3.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Recorded vehicle-side thread for the 2008 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.
Donor width/offset sits outside the known OEM envelope for this vehicle. 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.
Donor width/offset sits outside the known OEM envelope for this vehicle. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope.

The data below reflects known OEM specifications for at least one 2008 Buick LaCrosse factory configuration. Trims and option packages may differ. If your vehicle came with a different factory wheel and tire, use that as your baseline and confirm with the owner manual, door jamb tire label, or a Buick dealer, then validate with the on-page calculator.
| Bolt pattern | 5x115 |
| Center bore | 70.3 mm |
| Thread size | M12 x 1.5 |
| Wheel size | 17 x 7.5 in |
| Offset (ET) | +50 mm |
| Backspacing | 5.72 in |
| Tire size | 225/55R17 |
| Approx. overall tire diameter | 26.7 in (calculated from 225/55R17) |
If any of your OEM values differ, use your actual OEM numbers in the calculator on this page to compare changes accurately.
The OEM reference tire is about 26.7 in in diameter. Many owners explore plus sizes while keeping overall diameter close to maintain speedometer accuracy. The options below are examples only, not guarantees for your specific trim. Always validate with the calculator and a physical test fit.
What is the bolt pattern for the 2008 Buick LaCrosse?
5x115. Always match the wheel bolt pattern exactly for safe mounting.
Can I use 5x114.3 wheels on 5x115 hubs?
This is not recommended. The mismatch can cause improper seating, vibration, and stud stress. Use only 5x115 wheels.
What offset works if I change wheel width?
The OEM reference is +50 mm on a 17x7.5 in wheel. Reducing offset pushes the wheel outward and increases inner clearance by the same amount. Increasing offset pulls the wheel inward. Use the calculator to see inner and outer changes before buying and verify brake and fender clearance.
Do I need hub-centric rings with aftermarket wheels?
If the wheel’s center bore is larger than 70.3 mm, yes. Use rings that have a 70.3 mm inner diameter and an outer diameter that matches your wheel’s bore.
What lug nuts do I need?
Threads are M12 x 1.5. The seat type must match the wheel design. Verify conical vs ball vs mag seat before purchasing. Torque to the factory specification listed in your owner manual.
Will I need new TPMS sensors?
If your LaCrosse is equipped with TPMS and you are adding a second wheel set, you can transfer sensors or use compatible replacements. A relearn or programming procedure may be required. Check your owner manual and tool instructions.
What is the stock tire diameter and why does it matter?
The provided OEM tire 225/55R17 is about 26.7 in in overall diameter. Staying close to this helps keep speedometer and ABS behavior consistent. Always confirm clearance on the vehicle.
Are spacers safe to use?
Quality hub-centric spacers properly installed can be safe, but they change effective offset and may require longer studs or bolts. Recalculate with the on-page calculator and verify hardware engagement and clearances.
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.
