The following specifications are the known reference values provided for the 2017 GMC Sierra 2500HD. Fitment can vary by trim, drivetrain, package, wheel design, and tire equipment, so confirm the original equipment specification for your specific truck before purchasing.
| Specification | Known value |
|---|---|
| Bolt pattern | 8x180 |
| Center bore | 124.1 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 20 inches |
| Rim width | 8.5 inches |
| Wheel offset | ET40, or 40 mm |
| Backspacing | 5.82 inches |
| Known tire size | 275/55R20 |
| Tire section width | 275 mm |
| Tire aspect ratio | 55 percent |
| Tire rim diameter | 20 inches |
The 8x180 specification describes eight wheel studs on a 180 mm bolt circle. The wheel must also provide adequate clearance for the hub, brake components, suspension, and wheel fasteners. A matching bolt pattern alone does not prove that a wheel is safe or suitable.
The listed 275/55R20 tire has a nominal calculated outside diameter of approximately 31.9 inches. Actual measured diameter varies by tire model, approved rim width, inflation pressure, load, and tread wear. Use the calculator and the tire manufacturer’s documentation when comparing sizes.
Use the calculator to compare a potential donor vehicle or custom wheel with your 2017 GMC Sierra 2500HD. Select the donor vehicle under “Wheels from” and select the Sierra under “Installed on.” The comparison is intended to help identify differences in wheel diameter, width, offset, and tire sizing. It does not replace a physical clearance check or confirmation of load ratings.
For a wheel not represented by a donor vehicle, choose “Custom wheel size” and enter the rim diameter, rim width, and offset. Compare those values with the known reference values above. A change in offset or width can move the inner wheel edge closer to the suspension or move the outer edge closer to the fender.
Use “Custom tire size” to enter the tire section width and aspect ratio. The calculator updates the tire diameter comparison when rim diameter changes. Review the resulting diameter and width difference, then confirm the tire’s approved rim-width range, load index, speed rating, and vehicle application with the tire manufacturer.
Calculator results are screening information, not an approval of a specific wheel and tire combination. Always confirm the wheel’s 8x180 pattern, 124.1 mm hub relationship, fastener requirements, load capacity, brake clearance, and physical clearance on the vehicle.
Start with the vehicle’s exact trim and current equipment. Check the driver-door certification label, owner’s manual, original wheel markings, and a GMC dealer or parts source using the vehicle identification number. These sources are important because the supplied values may not represent every 2017 Sierra 2500HD configuration.
After installation, check clearances with the suspension loaded and unloaded where practical. Inspect for contact during steering, suspension compression, and reversing. Any rubbing, stud interference, loose hardware, or brake contact must be corrected before driving.
Plus sizing changes the wheel diameter while maintaining a similar overall tire diameter by using a lower aspect ratio. It can alter ride quality, wheel protection, steering response, speedometer behavior, braking clearance, and tire load capacity. The calculator can compare custom rim diameter, width, offset, and tire dimensions, but it cannot physically verify clearance or approve a load rating.
When considering a wider wheel or tire, compare the calculated section width and overall diameter with the known 275/55R20 reference. Check both sides of the tire and wheel because a change in offset moves the assembly inward or outward. A wheel with the same diameter and bolt pattern can still fail because of spoke-to-brake clearance, hub interference, insufficient load capacity, or fender contact.
For a heavy-duty pickup, preserve the required axle and tire load capacity for the truck’s placard and intended use. Confirm the replacement tire’s load index and pressure capability with the tire manufacturer. Do not reduce capacity to obtain a particular appearance or a larger wheel.
Inspect the hub face and wheel mounting surface before installation. Remove rust, dirt, paint buildup, and debris that could prevent the wheel from seating flat. Do not use spacers, adapters, or hub rings unless they are specifically engineered and approved for the vehicle, wheel, and load application.
Test-fit one wheel before mounting all four. Rotate the wheel by hand and inspect the brake caliper, suspension, steering components, wheel studs, and inner barrel. With the vehicle safely supported, turn the steering through its range and check for contact. Never rely on a jack alone while working under or near the vehicle.
Install the correct lug nuts by hand first to avoid cross-threading. Tighten them in a star pattern using the vehicle or wheel manufacturer’s specified torque procedure. The exact torque value is not provided here and must be confirmed from the GMC service information, owner’s manual, or wheel manufacturer. Recheck torque after the initial driving period specified by the applicable service instructions.
Set tire pressure according to the vehicle certification label unless a qualified tire professional provides a documented alternative for the installed load and tire combination. After installation, confirm that the tire-pressure monitoring system operates correctly and inspect for leaks, vibration, or pulling.
Useful equipment includes a properly rated floor jack, safety stands, wheel chocks, a compatible lug-nut socket, a calibrated torque wrench, a tire-pressure gauge, and a tread-depth or clearance measuring tool. Select tools that fit the actual fasteners and wheel design.
For a torque wrench and tire-pressure gauge, see automotive torque wrenches on Amazon and digital tire-pressure gauges on Amazon.
Use only wheel-cleaning products that are safe for the wheel’s finish. Avoid lubricating wheel studs or lug seats unless the vehicle or fastener manufacturer specifically directs it, because lubrication can change clamping force.
The known reference bolt pattern provided for this page is 8x180. Confirm the exact vehicle configuration and wheel application before ordering.
The known center bore is 124.1 mm. The replacement wheel must clear the hub. A smaller bore will not fit, while a larger bore requires careful evaluation of hub support and any correctly specified centering ring.
The supplied reference offset is ET40, or 40 mm, for the 20x8.5 wheel specification. Other offsets may change suspension and fender clearance and must be checked with the calculator and by physical test-fit.
The known tire size is 275/55R20. This is a reference value supplied for the page, not a guarantee that every trim uses the same tire. Verify the door-jamb label, owner’s manual, or VIN-specific OEM information.
No. Bolt pattern is only one part of fitment. The wheel must also have suitable hub clearance, offset, width, brake and spoke clearance, load capacity, fastener compatibility, and safe tire compatibility.
A larger bore may be possible when the wheel is correctly specified for the truck and is properly centered. The ring, if used, must match the hub and wheel precisely and be suitable for the application. Never force a wheel with a smaller bore over the hub.
No. The calculator compares donor and installed wheel and tire dimensions and allows custom sizes. It cannot verify structural load rating, brake clearance, lug-seat design, tire approval, or real-world rubbing. Use the results as a screening step followed by OEM, wheel-manufacturer, and tire-manufacturer confirmation.
Review speedometer effects, ground clearance, gearing, fender clearance, and the tire’s approved application. A diameter difference can affect vehicle systems and handling. Confirm the final size with GMC service information and the tire manufacturer before installation.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
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.
