Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Results are evaluated from bolt pattern, center bore direction, OEM width/offset envelope, and lug hardware – not bolt pattern alone.

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares:
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.
The following wheel and tire measurements are the known reference values provided for the 2016 GMC Terrain. Fitment can vary by trim, brake package, factory equipment, and regional specification, so confirm the information on the vehicle, in the owner documentation, and with a GMC parts source before purchasing.
| Specification | Known value |
|---|---|
| Bolt pattern | 5x120 |
| Center bore | 66.9 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 18 inches |
| Rim width | 7.0 inches |
| Wheel offset | ET46 |
| Backspacing | 5.31 inches |
| Tire size reference | 235/55R18 |
| Tire section width | 235 mm |
| Tire aspect ratio | 55 percent |
| Tire rim diameter | 18 inches |
These values describe the supplied reference configuration, not every possible 2016 GMC Terrain configuration. The bolt pattern, center bore, thread size, wheel offset, brake clearance, tire load rating, and overall tire diameter should all be checked before installation.
Use the calculator to compare a possible donor wheel with the wheel and tire setup on your 2016 GMC Terrain. Select the donor vehicle in the “Wheels from” field and select the Terrain in the “Installed on” field. The comparison is useful for reviewing wheel diameter, width, offset, bolt pattern, center bore, and related dimensions when those values are available.
Calculator results cannot replace a physical test fit or confirmation from GMC documentation and the wheel manufacturer. Always verify that the selected wheel clears the brake caliper, suspension, steering components, fender, and wheel-well liner through the full range of movement.
Do not rely on a seller’s statement that a wheel “fits” without checking the actual specifications. Ask for the wheel’s diameter, width, offset, backspacing, bolt pattern, center bore, load rating, and lug-seat type.
Plus sizing changes the relationship between wheel diameter, wheel width, tire sidewall height, and overall tire diameter. A larger rim does not automatically provide a safe upgrade. The replacement tire must be approved for the new rim width, and the final assembly must retain adequate clearance and load capacity.
The supplied reference tire is 235/55R18. If you test a different tire size in the calculator, compare its calculated diameter and width with this reference. A wider tire can contact the strut, suspension, fender, or liner. A shorter sidewall can reduce ride compliance and increase the risk of wheel or tire damage from potholes.
When changing wheel offset, remember that a lower offset generally moves the wheel farther outward, while a higher offset generally moves it farther inward. The actual result depends on wheel width as well as offset. Use the calculator for the dimensional comparison, then perform a careful clearance check with the vehicle safely supported.
Do not select a replacement solely because it has the same bolt pattern. Brake clearance, hub fit, load rating, tire diameter, lug hardware, and manufacturer approval remain essential.
Useful equipment for a wheel-swap inspection or installation may include a calibrated torque wrench, correct socket, jack and rated jack stands, wheel chocks, a tire-pressure gauge, and a tread-depth gauge. A hub-cleaning brush and a flashlight can help reveal corrosion or contact marks. A clearance check should be performed with the vehicle properly supported, never under a vehicle held only by a jack.
For checking hardware, see M14 x 1.5 lug nuts by wheel seat type. For installation measurement, see automotive calibrated torque wrenches. Confirm product specifications and suitability for your exact wheel before ordering.
What is the known bolt pattern for the 2016 GMC Terrain?
The supplied reference is 5x120. Confirm the vehicle and replacement wheel specifications before purchase because a matching pattern does not prove complete fitment.
What center bore is listed for this Terrain reference?
The supplied center bore is 66.9 mm. Check the actual wheel bore and hub fit. A larger wheel bore may require properly specified hub-centric rings, while a smaller bore may prevent installation.
What is the known factory-style tire reference?
The supplied reference is 235/55R18 on an 18 by 7.0 inch wheel with ET46 offset. This may not represent every trim or equipment package, so verify the tire placard and OEM documentation for the vehicle.
Can any 5x120 wheel be installed?
No. The wheel must also provide suitable center-bore fit, brake clearance, offset, backspacing, width, load rating, lug-seat compatibility, and tire compatibility. Use the calculator for comparison, then verify the physical installation.
Does the calculator confirm that a wheel is safe?
No. It compares available dimensions and lets you test custom wheel and tire sizes. It cannot inspect brake clearance, wheel condition, load ratings, tire approval, or contact during steering and suspension travel.
What happens when I change rim diameter in the calculator?
Changing rim diameter updates the tire diameter in the comparison. Review the resulting overall diameter and tire specifications, then compare them with the vehicle’s tire placard and OEM guidance.
Do I need new lug nuts when changing wheels?
Possibly. The known thread size is M14 x 1.5, but the correct lug nut also depends on the wheel’s seat style, required engagement, and any washer or shank design. Confirm the wheel manufacturer’s hardware requirements.
How can I confirm the exact fitment for my trim?
Check the tire and loading information label, owner documentation, factory parts information, and a GMC dealer or qualified wheel supplier. Compare those details with the calculator and the markings on the replacement wheel.
What should I do if the replacement wheel rubs?
Do not continue driving until the cause is identified. Check inner and outer clearance through steering and suspension movement, then consult the wheel and tire manufacturer or a qualified technician. Do not remove safety components or rely on spacers without proper engineering and approval.
