Known OEM Fitment For 2016 Buick LaCrosse

Notes: Other factory wheel and tire sizes may exist depending on trim or options. If your door jamb tire label or owner’s manual shows a different factory size, use that as your baseline and verify it with the on-page calculator and OEM service information.

How To Use The Wheel Interchange Calculator

• Set Installed on - choose 2016 Buick LaCrosse as your vehicle.
• Choose Wheels from - either a donor vehicle you want to compare or leave blank and use Custom wheel and tire size.
• Custom wheel size - enter rim diameter, width, and offset you are considering. The tool shows inner and outer clearance changes compared to your baseline.
• Custom tire size - enter section width and aspect ratio. When you change rim diameter, the calculator updates the comparison with the new tire diameter.
• Target overall tire diameter - keep close to the OEM baseline near 27.2 in to minimize speedometer and ABS impact. Staying within about 2 to 3 percent is a common guideline.
• Check inner clearance - watch the inner sidewall to strut or spring perch change. A positive change means more room, a negative change means less room.
• Check outer poke - ensure the outer sidewall does not protrude excessively past the fender line and will not contact the fender liner at full bump or steering lock.
• Record results - save or print the comparison so you can verify measurements physically on the car before buying.

Fitment Checklist Before You Buy

• Bolt pattern - wheel must be 5x120.
• Center bore - wheel bore must be 66.9 mm or larger. If larger, use hub centric rings sized to 66.9 mm.
• Lug hardware - threads are M14 x 1.5. Verify seat type matches the wheel design conical or ball seat. Do not mix seat types.
• Offset and width - compare to OEM 17x7 ET42. Use the calculator to ensure inner clearance to struts and outer fender clearance are acceptable.
• Tire diameter - keep overall diameter close to the OEM baseline to protect speedometer accuracy and driver assists.
• Brake and suspension clearance - confirm spoke-to-caliper clearance and inner barrel-to-strut clearance with a physical test fit.
• Load rating - wheel and tire load index must meet or exceed the vehicle requirements shown on the door placard.
• TPMS - plan for sensor transfer or new compatible sensors. Perform relearn per OEM procedure.
• Spacers - only if necessary and only hub-centric 5x120 with hub bore 66.9 mm. Ensure proper thread engagement with longer hardware when required.
• Torque - follow the Buick owner’s manual or service information for lug nut torque. Do not lubricate lug threads unless OEM specifies.

Plus Sizing And Common Upgrades

OEM reference diameter is about 27.2 in using 235/55R17. The examples below maintain a similar overall diameter to help with speedometer accuracy. These are examples only. Actual fitment depends on wheel width, offset, brake clearance, and suspension. Always verify with the calculator and a test fit.

• Plus 1 to 18 in - example tire sizes to evaluate:
  • 235/50R18 - approx 27.3 in diameter, very close to OEM.
• Plus 2 to 19 in - example tire sizes to evaluate:
  • 235/45R19 - approx 27.3 in diameter, very close to OEM.

Offset and width example: Stock is 17x7 ET42. If you consider 18x8, the wheel is 1.0 in wider total about 25.4 mm, which is about 12.7 mm wider per side. To keep inner clearance similar, reduce offset by roughly 12 to 13 mm. For example, an offset around ET30 may preserve inner clearance compared to stock. Use the calculator to fine tune and confirm outer poke.

Installation Tips

• Pre-fit - mount one wheel without the tire where possible to confirm spoke and barrel clearance over calipers and suspension.
• Clean mating surfaces - remove rust from the hub face and wheel mounting pad so the wheel seats flush.
• Hub centering - if the wheel bore is larger than 66.9 mm, install proper hub centric rings before mounting.
• Hardware - verify M14 x 1.5 threads and correct seat type for your wheels. Hand start all lugs to avoid cross-threading.
• Torque - snug in a star pattern, lower the vehicle, then torque to the OEM specification from the owner’s manual or service info. Do not use an impact gun for final torque.
• Re-torque - check lug torque after 50 to 100 miles.
• Steering sweep - with the car on the ground, turn lock to lock and drive over a small bump to confirm no rubbing under load.

FAQs

What is the bolt pattern for the 2016 Buick LaCrosse?
5x120.

What center bore do I need?
66.9 mm. If the wheel bore is larger, use hub centric rings to adapt to 66.9 mm.

What lug nuts or bolts does it use?
M14 x 1.5 thread. Verify whether your wheels require conical or ball seat hardware and match accordingly.

Can I run 18 or 19 inch wheels?
Often possible when overall tire diameter remains close to OEM and brake clearance is verified. Use the calculator to model sizes like 235/50R18 or 235/45R19 and then test fit.

What is the stock wheel and tire size?
One known OEM setup is 17x7 ET42 with 235/55R17 tires. Other factory sizes may exist by trim. Confirm your door label and owner’s manual.

Do I need hub centric rings?
If your aftermarket wheel’s center bore is larger than 66.9 mm, yes. Rings help the wheel seat accurately on the hub and reduce vibration.

What torque should I use on the lug nuts?
The exact torque can vary. Refer to the Buick owner’s manual or OEM service information for your trim and wheel size. Do not guess and do not lubricate threads unless the OEM specifies.

Will new wheels affect my speedometer?
They can. Keep the overall tire diameter close to the OEM baseline about 27.2 in. The calculator shows the expected speedometer difference.

Can I use spacers to clear brakes or fenders?
Only if necessary. Use hub-centric spacers that match 5x120 and 66.9 mm hub. Ensure proper thread engagement and hardware length. Re-check torque frequently.

How do I handle TPMS when changing wheels?
You can transfer OEM sensors if compatible with the new wheels or install new compatible sensors. Perform the relearn procedure specified by Buick.
