The confirmed wheel fitment data below is the information currently available for the 2015 GMC Sierra 1500. Factory wheel sizes and tire sizes can vary by trim, package, drivetrain, and equipment, so do not treat unknown values as universal specifications.
| Specification | Known value |
|---|---|
| Bolt pattern, studs x PCD | 6x139.7 |
| Center bore | 78.1 mm |
| Thread size | M14 x 1.5 |
| Factory rim diameter | Unknown and may vary by trim |
| Factory rim width | Unknown and may vary by trim |
| Factory wheel offset | Unknown and may vary by trim |
| Factory backspacing | Unknown and may vary by trim |
| Factory tire section width, aspect ratio, and rim diameter | Unknown and may vary by trim |
A compatible replacement wheel must match the 6x139.7 bolt pattern and provide a center bore that is compatible with the vehicle hub. The wheel also needs suitable offset, width, brake clearance, load capacity, and fastener-seat compatibility. Confirm the original equipment specifications from the vehicle door-jamb label, owner documentation, a GMC dealer, or an OEM parts source before ordering.
Use the calculator on this page to compare wheels from a donor vehicle with the wheels installed on your 2015 GMC Sierra 1500.
Because some factory specifications for this model are not provided here, enter the exact size shown on your vehicle or verify it through an OEM source before relying on the comparison. A result that shows matching bolt pattern alone does not prove that a wheel will safely fit.
Plus sizing changes the wheel diameter while maintaining a similar tire diameter by using a shorter tire sidewall. It can improve steering response and appearance, but it may also reduce ride comfort and increase the risk of wheel or tire damage on poor roads.
No specific factory or upgrade wheel diameter, width, offset, or tire size is provided for this 2015 GMC Sierra 1500. Do not select a plus-size combination based on the vehicle name alone. Enter the proposed custom wheel and tire dimensions in the calculator, then physically verify clearance and confirm the exact trim specifications through GMC or another reliable OEM source.
When comparing tire sizes, review section width, sidewall height, overall diameter, load index, and speed rating. A large change in overall diameter can affect clearance, speedometer accuracy, braking behavior, and electronic vehicle systems. Keep the final tire diameter within the range recommended by the vehicle manufacturer unless a qualified technician has evaluated the change.
Useful equipment includes a calibrated torque wrench, the correct lug nut socket, a jack and jack stands or an approved lift, wheel chocks, a tire pressure gauge, and a tread-safe inspection light. Use jack stands or a lift rated for the vehicle, and never work under a vehicle supported only by a jack.
Use the torque specification supplied by GMC, the wheel manufacturer, or the fastener manufacturer for your exact application. Tool listings are provided for convenience and do not replace the vehicle service information.
What is the bolt pattern for the 2015 GMC Sierra 1500?
The confirmed bolt pattern is 6x139.7, meaning six studs on a 139.7 mm pitch circle diameter. The bolt pattern must match exactly.
What is the center bore for the 2015 GMC Sierra 1500?
The confirmed center bore specification is 78.1 mm. A wheel with a smaller center bore generally cannot pass over the vehicle hub. A larger bore may need correctly sized hub-centric rings, depending on the wheel design and manufacturer guidance.
What lug nut thread size does this truck use?
The known thread size is M14 x 1.5. Thread size alone is not enough to identify the correct lug nut. Verify the nut's seat style, shank or washer requirements, thread engagement, and wheel manufacturer specifications.
What factory wheel size came on a 2015 GMC Sierra 1500?
The factory rim diameter, width, offset, backspacing, and tire dimensions are not provided as universal values here. They may vary by trim and equipment. Check the door-jamb tire label, owner documentation, the original wheel markings, or an OEM parts source, then enter the confirmed values into the calculator.
Can any 6x139.7 wheel fit this Sierra 1500?
No. Matching the bolt pattern does not confirm complete fitment. The wheel must also clear the brakes and suspension, have a suitable center bore, use compatible fasteners, meet load requirements, and provide safe tire and fender clearance.
Can I use a wheel with a larger center bore?
A larger center bore can sometimes be used with properly sized hub-centric rings, but the wheel must still be approved for the application and installed with compatible fasteners. A smaller center bore is generally not suitable because it may not fit over the hub.
Does the calculator guarantee that a custom wheel and tire combination will fit?
No. The calculator helps compare dimensions and shows how custom rim diameter, width, offset, and tire measurements relate to one another. It cannot verify every brake, suspension, fender, steering, load, or tire-clearance condition. Perform a physical inspection and confirm specifications before driving.
What should I do if the replacement wheel rubs?
Do not continue driving with persistent rubbing. Identify whether contact occurs at the brake, suspension, steering, inner liner, or fender, and have the combination inspected by a qualified technician. Changing tire size, wheel width, or offset may alter the clearance, but each change must be recalculated and physically verified.
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.
