Known OEM Fitment For 2014 Chevrolet Suburban 1500

The Suburban 1500 offered multiple factory wheel and tire packages in 2014. The values below are confirmed items from select trims or options. Items not listed may vary by trim or package. Always verify against your door-jamb tire placard, the owner’s manual, and the on-page calculator before purchasing.

Because multiple OEM packages existed, confirm your original equipment size by checking the driver’s door placard and VIN-specific OEM documentation. Use the calculator on this page to compare any donor wheel to your 2014 Suburban 1500.

How To Use The Wheel Interchange Calculator

• Start with your Suburban: Select 2014 Chevrolet Suburban 1500 as “Installed on (your vehicle).”
• Pick a donor: Choose the “Wheels from (donor vehicle).” If unknown, enter specs using Custom wheel size and Custom tire size.
• Enter wheel specs: Set rim diameter, rim width, and offset for the donor wheel. The tool will compute changes in poke and inner clearance.
• Enter tire size: Set section width and aspect ratio. Changing rim diameter updates the compared tire diameter so you can see speedometer and fender clearance impacts.
• Compare results: Watch red or green indicators for inner clearance to the suspension, outer poke vs the fender, brake-caliper clearance flags, and overall tire diameter difference.
• Dial it in: Nudge offset or width until inner clearance is safe and outer poke is within your fender limits. Keep total tire diameter close to OEM to maintain speedometer accuracy unless you plan to recalibrate.

If you do not know your exact OEM tire and wheel, confirm on the door placard and cross-check with the owner’s manual or a GM parts catalog by VIN.

Fitment Checklist Before You Buy

• Bolt pattern: New wheels must be 6x139.7.
• Center bore: Wheel bore must be at least 78.1 mm. Use hub-centric rings to reduce any larger bore to 78.1 mm.
• Lug nuts: Threads must be M14 x 1.5 and the seat type must match the wheel design.
• Brake clearance: Verify spoke and barrel clearance over front calipers. Test-fit when possible.
• Suspension and fender clearance: Use the calculator to check inner clearance to struts, UCA, and sway bar, and outer poke vs fender and mud flaps.
• Load rating: Wheel and tire load index must meet or exceed the GVWR requirements for a Suburban 1500.
• Tire diameter: Keep overall diameter close to your OEM package unless you have gearing and speedometer calibration plans.
• TPMS: Plan to transfer sensors or install compatible replacements and perform a relearn.
• Spare compatibility: Ensure the spare will still fit or plan an alternative.

Plus Sizing And Common Upgrades

The 2014 Suburban 1500 was offered with different OEM packages, including a 20 x 8.5 wheel and at least one 17-inch tire package. If you are moving between 17, 18, 20, or other diameters, use the calculator to keep overall tire diameter similar to your original package while adjusting width and aspect ratio. This helps maintain speedometer accuracy and reduces rubbing risk.

• Width changes: Increasing wheel width pushes the inner and outer lips outward by half the width change. Use offset adjustments to re-center if needed.
• Offset changes: Higher ET pulls the wheel inward. Lower ET pushes it outward. Balance inner clearance to suspension with outer fender clearance.
• Tire sidewalls: Shorter sidewalls improve steering response but can ride firmer and reduce pothole protection.
• Hub-centric fit: If using aftermarket wheels with a larger bore than 78.1 mm, install properly sized hub-centric rings for smoother highway ride.

Because OEM sizes varied by trim, do not assume another owner’s setup will fit yours. Confirm against your placard and with the calculator.

Installation Tips

• Test-fit first: Mount one front wheel without a tire to check caliper and suspension clearance. Rotate lock-to-lock.
• Clean mating surfaces: Remove rust from hubs and rotor hats. Wheels should sit fully flush on the hub.
• Dry torque hardware: Install clean, dry M14 x 1.5 lug nuts unless your OEM service info specifies otherwise.
• Proper torque and sequence: Hand-start all lugs, snug in a star pattern, then torque to the factory spec in a star pattern. Re-check after 50 to 100 miles.
• TPMS: Transfer sensors or install new ones. Perform a relearn per GM procedure after mounting.
• Check clearances loaded: After install, lower the vehicle, bounce the suspension, turn lock-to-lock, and inspect for contact.

Tools And Helpful Supplies

FAQs

• What is the bolt pattern on the 2014 Suburban 1500?

  6x139.7. Any replacement wheel must match this pattern.

• What center bore do I need?

  78.1 mm. If an aftermarket wheel has a larger bore, use hub-centric rings to reduce it to 78.1 mm.

• What is the lug thread size?

  M14 x 1.5. Use lug nuts that match both the thread and the wheel’s seat style.

• Were 17-inch wheels offered from the factory?

  A 265/70R17 tire size is a known OEM fitment on some trims. Brake and suspension clearances can vary by package, so verify with your door placard and the calculator.

• Is 20 x 8.5 ET31 an OEM spec?

  Yes, that wheel size and offset appeared on some factory packages, with approximately 5.47 in backspacing. Confirm your original package before matching.

• How do I ensure new tires keep my speedometer accurate?

  Use the calculator to keep overall diameter close to your OEM package. Large changes will affect speedometer and gearing.

• Do I need new TPMS sensors?

  You can transfer OEM sensors if compatible or install new compatible sensors. A relearn is required after installation.

• What torque should I use on the lug nuts?

  The required torque can vary. Use the value in your owner’s manual or GM service information for the 2014 Suburban 1500, and torque in a star pattern.
