Known OEM Fitment For 2010 Buick LaCrosse

The values below reflect factory equipment for at least one 2010 Buick LaCrosse trim. Other trims or appearance packages may differ. If a value you need is not listed or you suspect your trim varies, confirm with your VIN-specific OEM documentation and verify with the on-page calculator.

Bolt pattern5x120
Center bore66.9 mm
Thread sizeM14 x 1.5
OEM rim diameter17 in
OEM rim width7.0 in
OEM wheel offsetET 42 mm
OEM backspacing5.15 in
OEM tire size245/50R17

Notes:

  • Always match the bolt pattern exactly. 5x120 is not the same as 5x120.65.
  • Aftermarket wheels often have a larger center bore. Use hub-centric rings to size them down to 66.9 mm if needed.
  • Lug hardware must match M14 x 1.5 threads and the wheel seat type specified by the wheel maker.

How To Use The Wheel Interchange Calculator

  • Set Installed on to 2010 Buick LaCrosse. This locks in your baseline OEM specs shown above.
  • If you are considering wheels from another vehicle, select that in Wheels from. The tool will compare positions, clearances, and tire diameter if sizes are known.
  • To try aftermarket sizes, use Custom wheel size to change rim diameter, width, and offset. The calculator shows inner and outer position changes relative to OEM so you can judge strut, liner, and fender clearance.
  • Use Custom tire size to adjust section width and aspect ratio. The calculator updates overall tire diameter and speedometer change automatically when rim diameter changes.
  • Aim to keep overall tire diameter close to OEM. Many installers target within about 3 percent, but always follow OEM guidance and local regulations.
  • After modeling a setup, physically verify brake caliper clearance and fender clearance before driving.

Fitment Checklist Before You Buy

  • Bolt pattern: Must be 5x120.
  • Center bore: Vehicle hub is 66.9 mm. A wheel with a larger bore can be hub-centered using rings. A smaller bore will not fit.
  • Threads and hardware: M14 x 1.5. Match the seat type to the wheel design. Do not mix conical and ball seats.
  • Offset and width: Use the calculator to see inner clearance to strut and knuckle and outer poke to the fender. Small changes in offset or width can make a big difference. Ensure the tire and wheel do not contact suspension, brake hoses, or liners through full steering and suspension travel.
  • Brake clearance: Test-fit a front wheel to ensure the spokes and barrel clear the caliper. Spin the wheel by hand and look for light contact points.
  • Tire load and speed ratings: Meet or exceed the OEM ratings printed on your driver door placard.
  • Overall diameter: Keep close to OEM to protect ABS, transmission shift points, and speedometer accuracy. Use the calculator to check percent change.
  • TPMS: Plan to transfer your sensors or install compatible new sensors and complete the relearn procedure for your LaCrosse.
  • State inspection and insurance rules: Some regions limit how far tires can extend past the fender or how much the diameter may change. Verify locally.
  • Torque spec: Follow the torque specified in your owner’s manual or GM service information for your exact trim and wheel type. Re-torque after 50 to 100 miles.

Plus Sizing And Common Upgrades

Owners often explore plus sizing for appearance or handling. The 2010 LaCrosse came with 17 inch wheels on at least one trim. Other trims may have different factory sizes. If you are considering 18 inch or 19 inch packages, model them in the calculator first.

  • Choose a tire size that keeps overall diameter close to OEM. The calculator shows diameter and speedometer change.
  • Check inner clearance to struts and spring perches when increasing width. Also check outer poke to prevent fender contact on bumps and during steering.
  • Confirm brake caliper clearance with your intended wheel design. Larger diameters can help barrel clearance but spoke design still matters.
  • Winter setups often favor narrower tires to cut through slush. Keep the overall diameter close to stock and match load index.

Because trim and brake package differences may exist, do not assume another LaCrosse or GM wheel will fit without running the comparison and doing a physical test-fit.

Installation Tips

  • Inspect and clean the hub face. Remove rust and debris so the wheel seats flat.
  • If using hub-centric rings to adapt a larger wheel bore to 66.9 mm, install the rings fully seated and undamaged.
  • Move TPMS sensors carefully and replace service kits as required. Perform the GM relearn after installation.
  • Hand-thread M14 x 1.5 lug nuts to avoid cross-threading. Tighten in a star pattern in stages to the OEM torque spec for your trim and wheel type.
  • After the first drive, re-check for any contact marks and re-torque after 50 to 100 miles.

Tools And Helpful Supplies

FAQs

  • Which other vehicle wheels will fit my 2010 LaCrosse?

    Compatibility depends on multiple factors. A potential donor wheel must match 5x120 bolt pattern, have a center bore of 66.9 mm or larger with rings to 66.9, accept M14 x 1.5 hardware, and provide safe offset, width, and brake clearance. Use the calculator to compare the donor wheel to your LaCrosse and then test-fit.

  • Do I need hub-centric rings?

    Use rings if the aftermarket wheel’s center bore is larger than 66.9 mm. The ring sizes should step from the wheel’s bore down to 66.9 mm so the wheel centers properly on the hub.

  • Can I use spacers?

    Spacers change effective offset and can help spoke or strut clearance, but they add complexity. If used, choose quality hub-centric spacers with proper hub and wheel lips, ensure sufficient thread engagement for M14 x 1.5 hardware, verify local laws, and re-check torque. Model the needed thickness using the calculator before buying.

  • What is the correct lug nut torque for this car?

    The torque can vary by trim and wheel type. Do not guess. Use the 2010 Buick LaCrosse owner’s manual or GM service information for your VIN, torque in a star pattern, and re-torque after 50 to 100 miles.

  • Will 19 inch wheels fit without rubbing?

    It depends on wheel width, offset, tire size, and your brake package. Use the calculator to keep tire diameter near OEM and to check inner and outer clearances. Always test-fit and inspect for contact through full steering lock and suspension travel.

  • What is the difference between offset and backspacing?

    Offset is the distance from wheel centerline to the mounting face, measured in millimeters. Backspacing is the distance from the mounting face to the inner wheel edge, measured in inches. The calculator displays both so you can understand inner clearance and outer poke changes relative to OEM. OEM backspacing listed above is 5.15 in.

  • How close should my new tire diameter be to stock?

    Keep it as close as practical to maintain proper ABS, traction control, and speedometer function. Many installers target within roughly 3 percent, but always follow OEM guidance and local regulations. The calculator shows exact diameter and speedometer change.
