2014 Buick LaCrosse Wheel Fitment Guide

Known OEM Fitment For 2014 Buick LaCrosse

The values below reflect a known factory wheel and tire specification for the 2014 Buick LaCrosse. Trims and option packages can differ. If your vehicle varies, confirm using the on-page calculator and your OEM sources like the owner manual, door-jamb tire placard, or a Buick dealer by VIN.

Bolt pattern5x120
Center bore66.9 mm
Thread sizeM14 x 1.5
Rim diameter17 in
Rim width7.0 in
Wheel offsetET 42 mm
Backspacing5.15 in
Tire size235/50R17

If your factory wheels or tires are different, use those as your baseline in the calculator before comparing alternatives.

How To Use The Wheel Interchange Calculator

  • Set Installed on to your vehicle: 2014 Buick LaCrosse.
  • Enter your baseline specs. If stock, use: 17x7 ET42 wheel with 235/50R17 tire and 5x120 bolt pattern. The hub bore is 66.9 mm and threads are M14x1.5. If your trim differs, input your actual OEM specs from your door placard or manual.
  • Compare donor options. In Wheels from choose a potential donor vehicle or enter a Custom wheel size and Custom tire size.
  • Adjust rim diameter, width, and offset under Custom wheel size. The calculator updates tire diameter when you change rim diameter so you can maintain overall tire height.
  • Watch the clearance readouts. Key checks are:
    • Inner clearance to strut and suspension
    • Outer poke relative to fender edge
    • Overall tire diameter change and speedometer error
  • Target a small overall diameter change. Many owners aim to keep overall tire diameter within about 3 percent of stock to protect ABS, traction control, and speedometer accuracy.
  • If offset changes drive the wheel inboard or outboard too far, try a different offset in the calculator. Only consider spacers if necessary and if they are hub-centric and properly sized.
  • Save or print the comparison, then physically test fit when possible before mounting tires.

Fitment Checklist Before You Buy

  • Bolt pattern must be 5x120.
  • Center bore must seat on a 66.9 mm hub. If the wheel has a larger bore, use hub-centric rings with 66.9 mm inner diameter. If the wheel has a smaller bore, it will not fit.
  • Thread size is M14 x 1.5. Match your lug nuts to the wheel’s seat type and ensure correct thread engagement. As a general safety guideline, aim for at least the diameter of the stud in full thread engagement.
  • Offset and backspacing must clear suspension and fenders. The reference wheel is ET 42 with 5.15 in backspacing. Use the calculator to validate inner clearance and outer poke.
  • Brake and caliper clearance. Some wheel designs sit differently over the brakes even with the same specs. Verify spoke and barrel clearance.
  • Load rating. Wheels and tires must meet or exceed the vehicle axle and GVWR requirements.
  • TPMS. Plan to transfer, clone, or install compatible sensors and perform the relearn for the 2014 Buick LaCrosse.
  • Tire-to-body clearance. Check at full steering lock and over bumps with passengers and cargo.
  • Spare and rotation strategy. If you change overall diameter significantly, confirm spare tire compatibility or be prepared with an alternate plan.
  • Torque spec. Follow the Buick owner manual or service information for lug nut torque. Do not guess. Retorque after 50 to 100 miles.

Plus Sizing And Common Upgrades

Plus sizing changes rim diameter and tire profile to keep overall tire diameter close to stock. The goal is to maintain proper clearance, drivability, and accurate speedometer readings.

  • Start with your baseline 235/50R17 and wheel spec in the calculator.
  • Increase rim diameter in Custom wheel size and then adjust tire section width and aspect ratio in Custom tire size until overall diameter change is small.
  • Balance wheel width and offset to avoid inner rub or excessive poke. A wider wheel usually needs an offset adjustment to maintain inner clearance.
  • Always validate suspension, brake, and fender clearance in the calculator, then verify with a physical test fit.
  • If your trim has different factory sizes, use your exact OEM size as the starting point to keep changes proportional.

Installation Tips

  • Test fit one front and one rear wheel before mounting tires when possible. Verify hub-centric seating and caliper clearance.
  • Clean the hub face and center pilot. Remove rust and debris so the wheel sits flush. Do not apply grease on the friction face.
  • If using hub-centric rings, ensure the 66.9 mm inner diameter ring seats fully on the hub and in the wheel bore. Rings must be flush with no gaps.
  • Hand start all lug nuts. Tighten in a star pattern. Use a torque wrench to the OEM specification from your Buick manual. Avoid impact-only final tightening.
  • Re-torque after 50 to 100 miles and after any significant temperature swings.
  • Perform a TPMS relearn and set cold tire pressures to the values on your door placard, not the tire sidewall maximum.
  • After installation, turn the steering from lock to lock and drive over a gentle bump to check for rub under load.
  • If you made significant size or offset changes, get an alignment to protect handling and tire wear.

Tools And Helpful Supplies

FAQs

  • What were the factory wheel and tire specs for the 2014 Buick LaCrosse

    A known OEM setup is 17x7 ET42 with 235/50R17 tires, 5x120 bolt pattern, 66.9 mm center bore, and M14x1.5 threads. Some trims may use different sizes. Verify your vehicle’s door-jamb placard or owner manual and use those numbers as your calculator baseline.

  • Can I use wheels from another 5x120 vehicle

    Not automatically. Bolt pattern is only one factor. You must also match or adapt center bore to 66.9 mm, ensure correct offset and backspacing for clearance, confirm brake caliper clearance, and verify load rating and lug seat style. Use the calculator and physically test fit.

  • Do I need hub-centric rings

    If your aftermarket wheel has a larger center bore than 66.9 mm, use rings with a 66.9 mm inner diameter and the wheel’s outer diameter to center the wheel on the hub. If the wheel bore is smaller than 66.9 mm, it will not fit.

  • What lug nut torque should I use

    The correct torque depends on wheel design and Buick specifications. Check your owner manual or service information for the exact torque for your 2014 LaCrosse and wheel type. Recheck torque after 50 to 100 miles.

  • How much can I change tire diameter without issues

    Use the calculator to keep overall tire diameter changes small. Many aim for within about 3 percent of stock to minimize impact on ABS, traction control, and speedometer. Always verify clearance at full lock and under load.

  • Will I need new TPMS sensors

    If reusing your stock wheels, you can keep your existing sensors. For new wheels, transfer, clone, or install compatible sensors and complete a relearn for the 2014 LaCrosse following Buick procedures.

  • Can I use spacers to fix offset

    Only if necessary, and only hub-centric spacers that match 5x120 and seat on a 66.9 mm hub. Spacers may require longer wheel studs or appropriate hardware to maintain proper thread engagement. Validate in the calculator and follow local regulations.

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

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.
