2013 Buick LaCrosse Wheel Interchange

2013 Buick LaCrosse Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2013 Buick LaCrosse

The values below reflect known factory specifications for at least one 2013 Buick LaCrosse configuration. Other trims or option packages may differ. If any value on your vehicle is different, use the on-page calculator and confirm against your door-jamb tire label, owner’s manual, or OEM service information before buying parts.

Notes:

• Some LaCrosse trims may use different wheel diameters, widths, offsets, or tire sizes. Verify your exact trim and options.
• Do not confuse 5x120 with similar patterns like 5x115 or 5x120.65. The bolt circle must match exactly.

How To Use The Wheel Interchange Calculator

• Set Installed on (your vehicle) to 2013 Buick LaCrosse. The calculator will load the known spec above as your baseline.
• To compare a donor wheel, pick Wheels from and enter the donor vehicle details. The tool shows inner clearance and outer poke changes versus your LaCrosse.
• Exploring custom wheels: open Custom wheel size and enter the rim diameter, width, and offset you are considering.
• Exploring custom tires: open Custom tire size and enter section width and aspect ratio. The calculator updates total tire diameter and shows the change versus stock.
• Changing rim diameter updates the compared tire diameter in the results. If you increase wheel diameter, select a lower-profile tire to keep overall diameter close to stock.
• Key outputs to review: inner clearance to suspension and brakes, outer position relative to fenders, ride height change from tire diameter, and speedometer error.
• If anything is close, measure on the car. Check strut tube clearance, brake caliper to spoke clearance, and fender clearance at full steering lock and over bumps.

Fitment Checklist Before You Buy

• Bolt pattern must be 5x120. Do not force-fit similar patterns.
• Center bore is 66.9 mm. If the wheel bore is larger, use hub-centric rings sized to your wheel bore down to 66.9 mm. If the bore is smaller, the wheel will not fit.
• Threads are M14 x 1.5. Use lug nuts or bolts that match both thread and seat type specified by the wheel manufacturer. Do not mix conical, ball, or mag seats.
• Offset and width determine inner clearance and outer poke. Start from OEM 17x7 ET42 and use the calculator to verify suspension and fender room.
• Brake clearance: verify spoke-to-caliper and barrel-to-caliper clearance. Templates from the wheel maker help, but always test fit.
• Overall tire diameter: keep close to stock to protect ABS, stability control, and speedometer. A common guideline is within about 3 percent, then confirm with the calculator.
• Load ratings: wheel and tire load index must meet or exceed OEM requirements for your trim.
• TPMS: plan to transfer sensors or install compatible replacements. Perform the GM relearn after installation.
• Hardware: ensure proper lug nut shank depth and thread engagement. Do not use spacers unless they are hub-centric and you maintain correct engagement.
• Documentation: confirm all specs on your door-jamb label and owner’s manual for your exact VIN and trim.

Plus Sizing And Common Upgrades

Plus sizing changes wheel diameter and tire profile while keeping overall tire diameter near stock. The 2013 LaCrosse is known to use 17-inch wheels on at least one trim. Other trims may have larger OEM packages, but sizes vary. Use the calculator and verify with OEM sources before purchasing.

• Plus 1 concept: increase wheel diameter by 1 inch and select a tire with a lower aspect ratio so total diameter stays close to the 235/50R17 baseline.
• Plus 2 concept: same approach with a 2 inch wheel diameter increase. Verify brake clearance, offset, and fender room carefully.
• Offset and width matter more than diameter for clearance. For example-only math: moving from 17x7 ET42 to 18x8 ET42 keeps the wheel centered but reduces inner clearance by about 12.7 mm and pushes the outer lip out by about 12.7 mm due to the extra width. Adjust offset as needed, and confirm with the calculator and a physical test fit.
• Tire selection: the calculator will display total diameter and speedometer change as you try sizes. Aim to keep speedometer error minimal and clearance acceptable.

Installation Tips

• Test fit each front wheel without a tire first if possible to check caliper and hub clearance. Rotate by hand to confirm no contact.
• Clean the hub face and center pilot with a wire brush. Any rust or debris can cause lateral runout or vibration.
• If using hub-centric rings, seat them fully on the wheel. Do not stack rings.
• Install lug nuts by hand to avoid cross-threading. Threads should be clean and dry unless the OEM procedure specifies otherwise.
• Tighten in a star pattern and torque to the OEM specification from your owner’s manual or service manual. Do not rely on an impact gun for final torque.
• Re-torque after 50 to 100 miles of driving.
• Transfer or install TPMS sensors and perform the GM relearn procedure for your LaCrosse after mounting.
• Final checks: at full steering lock in both directions, verify clearance to fender liners, struts, and brake hoses. Recheck under load over bumps if possible.

FAQs

• Can I use wheels with a 5x115 or 5x120.65 pattern?

  No. The 2013 Buick LaCrosse spec listed here is 5x120. Close is not correct. Use only exact 5x120 wheels and verify hub bore and offset.

• Do I need hub-centric rings?

  Use rings if your aftermarket wheel’s center bore is larger than 66.9 mm. Select rings that reduce the wheel’s bore to 66.9 mm. If the wheel bore is smaller than 66.9 mm, the wheel will not seat on the hub.

• What offset should I choose for aftermarket wheels?

  The known OEM reference is ET 42 on a 17x7 wheel. Other offsets can work but must be checked with the calculator and a test fit to confirm inner clearance and outer fender room for your exact tire size and wheel width.

• What is the correct lug nut type?

  Thread size is M14 x 1.5. The seat type depends on the wheel design. Use the seat profile specified by the wheel manufacturer and never mix seat styles.

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

  As a general guideline, keep total diameter within about 3 percent of the OEM size to protect ABS, traction control, and accurate speedometer readings. Confirm with the calculator.

• Will larger diameter wheels fit my LaCrosse?

  Some trims use larger wheels, but sizes vary by package. Use the calculator to model diameter, offset, and width, then verify physically. Check brake clearance and fender room at full lock and over bumps.

• What torque should I use on the lug nuts?

  Follow the torque specification in your owner’s manual or OEM service information for your exact trim. Tighten in a star pattern and re-torque after 50 to 100 miles.
