These are vehicle-year records whose recorded OEM ranges overlap this 2019 GMC Sierra 2500HD. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 14 donor years. Listed 14 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -0.67 mm, inner change -5.68 mm. This uses aggregated width/offset ranges, not a specific wheel.
Lug thread is not fully recorded for this comparison. Hardware must match the 2019 GMC Sierra 2500HD studs and the selected wheel’s seat. Unknown hardware is not a match.
Bolt pattern data is incomplete for a full interchange decision.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionHub-centric rings ≈ 154.2 → 124.1 mm – not a verified installation requirement.
Hub-centric rings of about 154.2 → 124.1 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

The following wheel and tire values are the known reference specifications provided for the 2019 GMC Sierra 2500HD. Fitment can vary by trim, package, brake equipment, suspension configuration, and the specific wheel design. Confirm the label on your vehicle, the owner’s manual, and the wheel manufacturer’s specifications 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 |
| Tire size | 275/55R20 |
| Tire section width | 275 mm |
| Tire aspect ratio | 55% |
| Tire rim diameter | 20 inches |
These values do not establish every approved factory configuration or every compatible aftermarket wheel. Wheel load rating, brake clearance, tire load index, speed rating, and actual clearance are not provided here and must be confirmed before installation.
Use the calculator to compare wheels from a donor vehicle with the wheels installed on your 2019 GMC Sierra 2500HD. Enter or select the donor vehicle in the “Wheels from” field and your GMC in the “Installed on” field.
Review the bolt pattern, center bore, wheel width, diameter, offset, and backspacing comparison. A matching bolt pattern alone does not prove that a wheel is safe or will clear the brake components, suspension, fenders, hub, or bodywork.
You can also select “Custom wheel size” to enter a proposed rim diameter, rim width, and offset. Use “Custom tire size” to enter the tire section width and aspect ratio. When you change the rim diameter, the calculator updates the tire diameter in the comparison, helping you evaluate changes in overall size.
Use the calculator as a screening tool, then confirm the final wheel and tire specifications with the wheel manufacturer, tire manufacturer, and GMC OEM documentation. Physically test-fit one complete wheel and tire assembly when possible.
Plus sizing changes the relationship between wheel diameter, tire sidewall height, overall tire diameter, and available clearance. A larger wheel does not automatically provide a suitable upgrade, and a wider tire can increase contact with suspension or body components.
For a custom setup, enter the proposed wheel diameter, width, and offset in the calculator, then enter the proposed tire section width and aspect ratio. Compare the resulting tire diameter and estimated position to the known 275/55R20 reference configuration.
Keep the replacement tire’s load capacity appropriate for a heavy-duty pickup. Do not select a tire solely because its dimensions appear close. Confirm the wheel’s load rating, tire load index, inflation requirements, and manufacturer-approved application.
Because no complete list of approved alternate sizes or trims is provided, treat every plus-size or aftermarket combination as requiring separate confirmation. Check GMC documentation, the tire placard, wheel manufacturer data, and tire manufacturer data before ordering.
Clean the hub mounting surface and the wheel mounting surface before installation. Rust, paint buildup, dirt, or debris can prevent the wheel from seating correctly and can contribute to looseness or vibration.
Use only lug nuts with the correct M14 x 1.5 thread and the correct seat type for the wheel. Thread size alone does not confirm that a lug nut is compatible with a particular wheel.
Install the wheel by hand and tighten the lug nuts in a star or crisscross pattern. Lower the vehicle enough to prevent rotation, then torque the lug nuts to the vehicle or wheel manufacturer’s specified value. A torque value was not provided here, so do not guess.
After installation, check clearance with the steering turned in both directions. Inspect for contact behind the wheel, around the tire shoulder, and inside the wheel well. Recheck lug torque according to the vehicle or wheel manufacturer’s instructions after driving.
Stop driving if you notice vibration, rubbing, loss of pressure, loose hardware, or unusual handling. Have the installation inspected by a qualified technician.
A calibrated torque wrench, properly sized socket, vehicle jack and jack stands rated for the truck, wheel chocks, and a tire pressure gauge are useful for a careful installation. Follow the vehicle owner’s manual for lifting points and support procedures. Never rely on a jack alone while working beneath or beside a raised vehicle.
Confirm tool size and product suitability before purchase. A torque wrench must be used according to its instructions and checked for calibration when required.
What is the bolt pattern for the 2019 GMC Sierra 2500HD?
The known bolt pattern is 8x180. Confirm the specification for your exact vehicle and wheel before purchase.
What is the center bore?
The known center bore is 124.1 mm. A wheel with a smaller center bore will not fit over the hub. A larger bore may require a properly specified hub-centric solution, subject to the wheel manufacturer’s instructions.
What wheel size is listed for this vehicle?
The provided reference configuration uses a 20-inch diameter, 8.5-inch-wide wheel with ET40 offset and 5.82-inch backspacing. This is not a complete list of every factory or aftermarket configuration.
What tire size is listed?
The provided reference tire size is 275/55R20, with a 275 mm section width, 55 percent aspect ratio, and 20-inch rim diameter.
Can I use wheels from another vehicle?
Possibly, but the donor wheel must be checked for bolt pattern, center bore, thread and lug compatibility, diameter, width, offset, backspacing, load rating, brake clearance, and tire compatibility. Use the wheel interchange calculator for an initial comparison and confirm the result with the wheel manufacturer.
Does the calculator confirm that a wheel is safe?
No. The calculator compares the entered dimensions and updates tire diameter when the rim diameter changes. It cannot replace physical clearance checks, load-rating verification, OEM documentation, or manufacturer approval.
Do I need the same offset and backspacing?
Using different offset or backspacing changes the wheel’s position relative to the suspension and fender. Enter the proposed dimensions in the calculator and verify actual clearance. Do not rely on appearance alone.
What lug nuts should I use?
The known thread size is M14 x 1.5, but the correct lug nut also depends on the wheel’s seat design and the vehicle’s hardware requirements. Match the thread, seat type, length, and retention requirements before installation.
Where can I confirm the final specifications?
Check the vehicle door-jamb tire label, owner’s manual, GMC service or parts documentation, the wheel manufacturer’s fitment and load-rating data, and the tire manufacturer’s specifications. If any information conflicts, pause the installation and obtain clarification from a qualified technician or the relevant manufacturer.
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.
