2010 Buick Lucerne Wheel Interchange

2010 Buick Lucerne Wheel Fitment And Interchange Guide

Known OEM Fitment For 2010 Buick Lucerne

The following specifications reflect known OEM fitment data for the 2010 Buick Lucerne. Some trims and option packages may use different wheel and tire sizes. Always verify against your door-jamb tire label and the owner’s manual, then confirm with the on-page calculator before purchasing.

Approximate OEM tire diameter: about 27.2 in (calculated from 235/55R17). If your vehicle shows a different factory size on the door label, use that size as your baseline in the calculator.

How To Use The Wheel Interchange Calculator

The calculator on this page lets you compare a donor wheel and tire to your 2010 Buick Lucerne, then fine tune custom wheel and tire sizes to predict clearance changes.

• Set Installed on (your vehicle) to 2010 Buick Lucerne with the OEM size shown on your door label or the known size above.
• Enter Wheels from (donor vehicle) when you are evaluating a takeoff set or an aftermarket wheel. If you only know wheel specs, use the Custom wheel size fields.
• Adjust Custom wheel size: rim diameter, rim width, and offset. The tool shows inner and outer clearance changes versus your baseline to help avoid strut and fender rub.
• Adjust Custom tire size: section width and aspect ratio. The calculator updates overall tire diameter so you can target a similar rolling diameter.
• Review the results for: inner clearance to strut or control arms, outer poke relative to fender, ride height change, and speedometer error.

Tip: Keep overall tire diameter close to stock to protect ABS, traction control, and speedometer accuracy. Many installers aim for within about 1 to 3 percent of OEM diameter.

Fitment Checklist Before You Buy

• Confirm bolt pattern is 5x115. Do not assume 5x114.3 will fit.
• Confirm center bore is 70.3 mm. If aftermarket wheels have a larger bore, plan for hub centric rings to 70.3 mm.
• Confirm thread size is M12 x 1.5 and lug seat style matches the wheel. If unsure, reuse OEM lug nuts with OEM wheels or verify the seat type with the wheel manufacturer.
• Match or properly account for offset and backspacing. Use the calculator to ensure inner clearance to the strut and outer clearance to the fender.
• Check brake caliper clearance. Some designs have thicker spokes or smaller barrel diameters that can contact calipers.
• Keep tire load and speed ratings equal to or higher than OEM.
• Keep overall tire diameter close to the OEM baseline (about 27.2 in for 235/55R17) to maintain vehicle systems.
• Inspect suspension ride height, worn bushings, and alignment. Lowered or sagging suspensions reduce clearance.
• Test fit one wheel, turn lock to lock, compress the suspension, and check for any rubbing before mounting tires.

Plus Sizing And Common Upgrades

Plus sizing can improve appearance and handling if clearances and load ratings are respected. Since actual compatibility can vary by trim and brake package, treat the following as mathematical comparisons only and verify with the calculator and a physical test fit.

• Baseline diameter: 235/55R17 is about 27.2 in.
• 18 inch exploration: sizes near 27.2 in to evaluate in the calculator include 235/50R18 (about 27.3 in) and 245/50R18 (about 27.6 in). Check inner clearance if increasing tire width.
• 19 inch exploration: sizes near 27.2 in include 235/45R19 (about 27.3 in). Wider options may require more offset care.

Wheel width and offset guidance must be verified per wheel design. The OEM reference is 17x7 ET46 with about 5.31 in backspacing. When you change width or offset, the calculator will show how far the wheel moves inboard or outboard. Preserve inner clearance to suspension components and avoid excessive poke past the fender.

Installation Tips

• Test fit first without the tire if possible. Spin the wheel by hand to check for caliper and knuckle clearance.
• Clean the hub face and center pilot with a wire brush so the wheel seats flush. Remove rust scale and debris.
• If using hub centric rings, ensure they are 70.3 mm at the hub side and match the wheel bore on the other side. Rings must seat fully.
• Use the correct lug nuts for your wheel’s seat type. Hand start every lug to avoid cross-threading.
• Tighten in a star pattern in stages using a calibrated torque wrench. Final torque should follow the 2010 Buick Lucerne OEM specification in the owner’s manual. Re-torque after 50 to 100 miles.
• TPMS: Transfer or program compatible sensors. Use new TPMS service kits when reinstalling sensors to prevent leaks.
• After installation, check for rubbing at full steering lock, over bumps, and with passengers or cargo.

FAQs

What is the bolt pattern for the 2010 Buick Lucerne?
5x115.

Can I use wheels with a 5x114.3 pattern?
This is not recommended. The 0.7 mm difference can stress studs and nuts, compromise clamping force, and create vibration. Use only 5x115 wheels for a proper fit.

What center bore do I need and do I need hub rings?
The Lucerne hub is 70.3 mm. OEM wheels match that. Many aftermarket wheels have a larger bore and require hub centric rings to 70.3 mm for proper centering and to reduce vibration.

What is the factory wheel offset?
Known OEM reference is ET 46 mm for a 17x7 wheel. Other trims may differ. Use your door label and the calculator to compare any alternative setup.

What is the stock tire size and overall diameter?
235/55R17 with an approximate overall diameter of about 27.2 in.

What lug nut thread size does it use?
M12 x 1.5. Verify lug seat style before buying aftermarket lug nuts.

What torque should I use on the lug nuts?
Lug torque can vary by trim and wheel material. Do not guess. Use the value in the 2010 Buick Lucerne owner’s manual or an OEM service source, and re-torque after 50 to 100 miles.

Will 18 inch or 19 inch wheels fit?
Fitment depends on wheel width, offset, tire size, and your trim’s brake package. Use the calculator to keep overall diameter close to stock, verify clearances, and perform a test fit before mounting tires.
