2007 GMC Acadia Wheel Interchange

2007 GMC Acadia Wheel Fitment and Interchange Guide

Known OEM Fitment For 2007 GMC Acadia

The following wheel and tire specifications are the known OEM fitment data provided for the 2007 GMC Acadia. Specifications can vary by trim, package, market, or replacement wheel, so confirm the details on your vehicle before purchasing.

The supplied data identifies a 6-lug, 6x132 wheel with a 74.5 mm center bore and M12 x 1.5 wheel fasteners. Do not rely on bolt pattern alone. The wheel must also clear the brake components and suspension, use a suitable center bore, provide adequate load capacity, and maintain safe tire clearance.

Confirm the original equipment specification using the tire-information label, owner’s manual, service documentation, or a GMC dealer. Check the markings on the existing wheel as well, because a vehicle may have replacement wheels or a different configuration from the listed reference fitment.

How To Use The Wheel Interchange Calculator

Use the calculator to compare wheels from a donor vehicle with wheels installed on your 2007 GMC Acadia. Start by entering or selecting the donor wheel and tire information, then set the Acadia as the vehicle receiving the wheels.

1. Enter the donor wheel diameter, width, and offset.
2. Enter the donor tire section width and aspect ratio.
3. Review the comparison against the known Acadia reference values: 18 x 7.5 inches, ET50, and 255/65R18.
4. Use the custom wheel size controls to test a different rim diameter, width, or offset.
5. Use the custom tire size controls to compare another section width or aspect ratio.
6. When you change rim diameter, review the updated tire diameter shown by the calculator. A different wheel diameter normally requires a tire with a different sidewall size to maintain a similar overall diameter.

The calculator is a comparison and planning tool, not a substitute for a physical test fit or manufacturer approval. It cannot confirm brake clearance, spoke clearance, hub engagement, wheel load rating, tire load index, or clearance under all steering and suspension positions.

Fitment Checklist Before You Buy

Before ordering wheels or tires, verify each of the following against the vehicle and the wheel manufacturer’s specifications:

• Confirm the 6x132 bolt pattern and measure the wheel’s actual mounting pattern when buying used parts.
• Confirm that the 74.5 mm center bore is compatible. A larger bore may require correctly sized hub-centric rings; a smaller bore will not fit over the hub.
• Check the wheel offset and width. Changes from the known ET50 and 7.5-inch reference can alter inner suspension clearance, outer fender position, steering feel, and tire rubbing risk.
• Verify the wheel’s load rating is suitable for the Acadia and its intended use.
• Confirm tire load index, speed rating, construction, and overall diameter using the tire manufacturer’s data.
• Make sure the tire is approved for the wheel width and does not contact the strut, control arm, fender liner, or bodywork.
• Check clearance with the steering turned fully left and right, and with the suspension compressed if possible.
• Confirm that the wheel fasteners match the wheel seat design. M12 x 1.5 thread size alone does not identify the correct lug nut seat.
• Inspect used wheels for cracks, bends, corrosion around the bead seat, damaged threads, and repaired impact damage.

Plus Sizing And Common Upgrades

Plus sizing changes the wheel diameter while using a lower-profile tire to keep the overall tire diameter reasonably close to the original reference. The known reference for this page is 255/65R18, but no alternate factory-approved sizes have been provided here. Do not treat an unlisted size as compatible without checking the owner’s manual, the vehicle placard, tire manufacturer data, and wheel manufacturer specifications.

The calculator can help compare custom wheel diameter, width, and offset combinations. It also updates the displayed tire diameter when the rim diameter changes. Use the result as an initial comparison only. A similar calculated diameter does not guarantee adequate clearance or correct load capacity.

Wider wheels or tires may improve dry-road contact but can increase the risk of rubbing and may change steering response, road noise, hydroplaning behavior, and fuel economy. Lower-profile tires generally provide less sidewall protection from potholes. Any upgrade should preserve safe load capacity and maintain sufficient clearance throughout steering and suspension travel.

Installation Tips

Have the installer clean the hub face and wheel mounting surface before fitting the wheel. Rust, dirt, paint buildup, or debris between these surfaces can prevent the wheel from seating correctly and may cause vibration or fastener loosening.

Install the correct M12 x 1.5 fasteners only if their seat type and length are approved for the specific wheel. Start every fastener by hand to avoid cross-threading. Tighten in a star pattern, then use a calibrated torque wrench to apply the torque specified by GMC or the wheel manufacturer. Do not guess the torque value.

After installation, check for contact at full steering lock and inspect the inner wheel, tire sidewall, suspension, and fender areas. Recheck fastener torque after the initial driving period specified by the wheel manufacturer or installer. Stop driving if you notice vibration, rubbing, pulling, air loss, or unusual noise.

Tools And Helpful Supplies

Useful equipment for a careful wheel fitment inspection and installation may include:

• A calibrated torque wrench and the correct socket
• A jack and jack stands rated for the vehicle
• A tire-pressure gauge
• A tread-depth gauge
• A straightedge or measuring tool for checking wheel and tire clearance
• A wire brush and suitable cleaner for the hub mounting surface
• Approved hub-centric rings when required by the wheel manufacturer

For compatible options, compare the tool specifications with your vehicle and wheel requirements before purchase: automotive torque wrench and automotive jack stands.

FAQs

What is the bolt pattern for a 2007 GMC Acadia?
The known bolt pattern is 6x132. Confirm the vehicle and wheel specifications before purchase, especially when dealing with used or aftermarket wheels.

What is the center bore of the 2007 GMC Acadia wheel fitment?
The known center bore is 74.5 mm. A wheel with a larger bore may need properly sized hub-centric rings, while a smaller bore will not fit over the vehicle hub.

What is the known original tire size?
The provided reference tire size is 255/65R18, consisting of a 255 mm section width, a 65 percent aspect ratio, and an 18-inch rim diameter. Trim-specific or market-specific differences should be confirmed from the vehicle placard and OEM documentation.

What wheel offset is listed for this Acadia fitment?
The known wheel offset is ET50, with a listed rim size of 18 x 7.5 inches. A different offset can move the wheel inward or outward and may create clearance or rubbing problems.

Can I use wheels from another vehicle?
Possibly, but the donor wheel must match the 6x132 bolt pattern and be compatible with the 74.5 mm hub, fastener requirements, brake clearance, wheel load rating, offset, width, and tire requirements. Use the wheel interchange calculator for an initial comparison, then verify the manufacturer’s specifications and perform a physical clearance check.

Does a larger center bore make a wheel incompatible?
Not necessarily. A larger center bore can sometimes be matched with correctly sized hub-centric rings approved for the wheel. The ring must fit both the vehicle hub and the wheel bore. A center bore smaller than 74.5 mm will not fit over the hub.

Does changing wheel diameter change tire diameter?
Changing wheel diameter requires a different tire sidewall size if you want to keep the overall tire diameter similar. The calculator updates the displayed tire diameter when the rim diameter changes, but the result still requires clearance, load, speed-rating, and manufacturer approval checks.

What lug nuts should I use?
The known thread size is M12 x 1.5, but thread size alone is not enough. The lug nut seat style, shank or tip dimensions where applicable, overall length, and wheel manufacturer requirements must also match. Confirm the correct fasteners before installation.

Where can I confirm the exact fitment for my trim?
Check the tire-information label, owner’s manual, GMC service information, the existing wheel markings, or a GMC dealer. If those sources conflict with a general fitment listing, have the vehicle and wheel specifications professionally verified before driving.
