Recorded OEM specifications for the 2020 GMC Yukon, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.

These are vehicle-year records whose recorded OEM ranges overlap this 2020 GMC Yukon. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 66 donor years. Listed 24 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 -1.67 mm, inner change -4.68 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionHub-centric rings ≈ 78.3 → 78.1 mm – not a verified installation requirement.
Hub-centric rings of about 78.3 → 78.1 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.
Lug thread is not fully recorded for this comparison. Hardware must match the 2020 GMC Yukon studs and the selected wheel’s seat. Unknown hardware is not a match.
Bolt pattern data is incomplete for a full interchange decision.

This guide covers the supplied reference specifications for the 2020 GMC Yukon. Equipment can vary by trim, package, suspension, brake configuration, and wheel option, so confirm the exact vehicle details before ordering wheels or tires.
The following values are the known reference fitment data provided for this page. They should not be treated as a complete fitment list for every 2020 GMC Yukon configuration.
| Specification | Known reference value |
|---|---|
| Bolt pattern | 6x139.7, meaning 6 studs on a 139.7 mm pitch circle diameter |
| Center bore | 78.1 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 18 inches |
| Rim width | 8.5 inches |
| Wheel offset | ET24, or 24 mm |
| Backspacing | 5.19 inches |
| Reference tire size | 265/65R18 |
| Tire section width | 265 mm |
| Tire aspect ratio | 65 percent |
Confirm the original equipment tire placard, owner’s manual, wheel markings, and current tire size for your specific Yukon. Also verify load and speed ratings before selecting replacements. The bolt pattern alone does not prove that a wheel will clear the brakes, suspension, hubs, or bodywork.
Use the calculator to compare a donor vehicle’s wheel and tire measurements with the measurements you plan to install on your 2020 GMC Yukon. Select the donor vehicle under “Wheels from” and select the Yukon under “Installed on.”
Use calculator results as a screening tool, not as a substitute for physical verification. The calculator cannot confirm every brake-caliper shape, spoke profile, tire brand variation, suspension condition, or body clearance issue.
OEM parts catalogs, the vehicle door-jamb label, and the wheel manufacturer’s fitment data are the best sources for final confirmation. If those sources disagree, pause the installation until the discrepancy is resolved.
Plus sizing changes the wheel diameter while usually reducing tire sidewall height to maintain a similar overall tire diameter. This can sharpen steering response, but it may also reduce ride comfort and increase the risk of wheel or tire damage from potholes.
There is no single upgrade size that can be confirmed for every 2020 GMC Yukon from the information supplied here. Use the calculator to test a proposed rim diameter, width, and offset, then compare the resulting tire diameter and clearance with the vehicle’s current setup.
Have wheels and tires installed by a qualified technician, especially when changing wheel width, offset, tire diameter, or load rating. Before final tightening, clean the hub and wheel mounting faces and make sure the wheel sits flush against the hub.
Useful equipment includes a calibrated torque wrench, correct socket, jack and properly rated jack stands, wheel chocks, a tire pressure gauge, and a hub or wheel-cleaning brush. A wheel fitment template can help check spoke and brake clearance before purchasing tires.
For tool and supply research, see automotive torque wrenches on Amazon and wheel fitment and brake-clearance templates on Amazon. Product specifications and suitability should be checked before use.
The supplied reference bolt pattern is 6x139.7. Confirm this against the vehicle and wheel documentation before ordering.
The supplied reference center bore is 78.1 mm. A wheel with a larger bore may require an appropriate hub-centric solution, while a smaller bore generally will not fit over the hub without machining. Confirm compatibility with the wheel manufacturer.
The supplied reference tire size is 265/65R18. Tire size can vary by trim or factory wheel package, so check the door-jamb tire label and current vehicle documentation.
No. Bolt pattern is only one part of fitment. Center bore, offset, backspacing, wheel width, brake clearance, lug-seat design, load rating, and tire clearance must also be confirmed.
The supplied reference offset is ET24, or 24 mm, with a listed backspacing of 5.19 inches. A different wheel width can change the effect of the same offset, so compare the complete wheel dimensions in the calculator.
A different rim diameter may be possible, but it must be checked for brake clearance, tire availability, load capacity, overall tire diameter, and body and suspension clearance. Enter the proposed custom wheel and tire sizes in the calculator before purchasing.
No. It compares the supplied dimensions and calculates geometric differences. It cannot guarantee spoke clearance, brake clearance, tire-brand dimensions, lug compatibility, or clearance under all suspension and steering conditions.
Check the driver-door tire and loading label, owner’s manual, vehicle identification number records, OEM parts information, and the wheel manufacturer’s application guide. A qualified tire and wheel technician can also perform a test fit before final 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.
