2011 Chevrolet Suburban 1500 Wheel Interchange

2011 Chevrolet Suburban 1500 Wheel Fitment Guide

Known OEM Fitment For 2011 Chevrolet Suburban 1500

The values below reflect fitment data provided for at least one OEM configuration of the 2011 Chevrolet Suburban 1500. Factory packages can vary by trim and option package. If a value is not listed for your specific wheel and tire size, use the on-page calculator and verify against your owner’s manual and the driver door jamb tire placard.

Note: The presence of a 20x8.5 ET31 wheel and a 265/70R17 tire indicates multiple factory packages existed in 2011. Confirm your vehicle’s original size on the door sticker and compare in the calculator before purchasing different wheels or tires.

How To Use The Wheel Interchange Calculator

• Set Installed on (your vehicle) to 2011 Chevrolet Suburban 1500. This establishes your baseline hub, brake, and body clearances.
• Pick Wheels from (donor vehicle) if you are considering a take-off wheel set. The tool will auto-calculate differences in inner clearance and outer poke.
• Use Custom wheel size to test rim diameter, width, and offset. Small changes in offset can significantly affect inner clearance to the suspension and outer fender coverage.
• Use Custom tire size to set section width and aspect ratio. The calculator will update overall tire diameter automatically when you change rim diameter.
• Aim to keep overall tire diameter within about 3 percent of your OEM tire size to help maintain speedometer accuracy and reduce rub risk. Always verify brake caliper clearance and suspension clearance.
• Review results for:
  • Inner clearance change vs. strut, control arm, and frame
  • Outer poke change vs. fender and splash liner
  • Overall diameter change vs. potential rub on compression or at full steering lock
• Finalize by cross-checking with your door jamb placard and owner’s manual for the correct tire load index, speed rating, and pressure.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 6x139.7. Do not use wheels that require wobble bolts or adapters without professional evaluation.
• Center bore: Vehicle hub is 78.1 mm. Aftermarket wheels with a larger bore should use hub-centric rings with 78.1 mm inner diameter.
• Thread size and seat type: Studs are M14 x 1.5. Confirm the lug nut seat style matches the wheel design, typically conical or mag-seat depending on the wheel.
• Offset and backspacing: OEM reference includes ET 31 mm and 5.47 in backspacing on an 8.5 in wheel. If you change offset or width, use the calculator to ensure inner and outer clearance remain safe.
• Brake and suspension clearance: Visually verify spoke-to-caliper and barrel-to-caliper clearance. Calculator values help, but a physical test fit is recommended.
• Tire load and speed rating: Match or exceed the OEM ratings from the door placard.
• TPMS compatibility: 2011 models use tire pressure monitoring. Plan to transfer or replace sensors and perform relearn as required.
• Overall diameter: Keep within a conservative tolerance around OEM to limit rub and speedometer error.

Plus Sizing And Common Upgrades

Many owners explore different wheel and tire combinations for appearance or performance. Because OEM sizes vary by trim, do not assume your vehicle came with the same size as the data listed above. Follow the steps below for safe plus sizing.

• Choose a target rim diameter and width, then set those values in the Custom wheel size fields.
• Adjust tire section width and aspect ratio in Custom tire size until overall diameter change is within about 3 percent of your OEM tire size.
• Watch inner clearance and outer poke. Larger width or lower offset can push the tire into fenders or out past the body. Higher offset can move the tire into suspension components.
• Confirm that tire load index meets or exceeds the truck’s requirements. Heavier wheels and tires can affect braking distance and ride quality.
• When moving to shorter sidewalls, expect firmer ride and increased impact sensitivity. Inspect wheels after pothole impacts.

Installation Tips

• Test fit every wheel on the hub to confirm center bore fit, brake clearance, and stud engagement before mounting tires.
• Clean the hub face and wheel mounting pad. Remove rust and debris to ensure true mounting. A small amount of anti-seize on the hub pilot can help prevent future sticking. Do not lubricate lug studs unless the vehicle manufacturer specifies.
• If using aftermarket wheels with a larger center bore, install hub-centric rings sized to 78.1 mm inner diameter and the wheel’s outer bore.
• Use new lug nuts that match M14 x 1.5 thread and the correct seat type for the wheel. Hand start all lugs.
• Tighten in a star pattern and torque to the factory specification from your owner’s manual. Re-torque after 50 to 100 miles.
• After installation, turn the steering from lock to lock and compress the suspension over a bump to check for rubbing.
• Relearn or program TPMS sensors and set tire pressures to the door placard values.
• Schedule an alignment after significant changes to wheel width, offset, or tire size.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14 x 1.5 lug nuts
• 78.1 mm hub-centric rings
• TPMS sensors compatible with GM

FAQs

• What is the bolt pattern for the 2011 Chevrolet Suburban 1500?

  6x139.7.

• What is the center bore size?

  78.1 mm.

• What lug nut thread size does it use?

  M14 x 1.5. Use lug nuts with the correct seat type for your wheels.

• Why do I see both a 20 inch wheel and a 17 inch tire listed?

  Different OEM packages existed in 2011. The values shown reflect known configurations. Check your door jamb placard and compare with the calculator to match your exact setup.

• What offset should I use with aftermarket wheels?

  Offset depends on wheel width and brake or fender clearance. One OEM reference is ET 31 mm on an 8.5 inch wheel. Use the calculator to test your width and offset, then verify clearances physically.

• Do I need hub-centric rings?

  Only if your aftermarket wheel’s center bore is larger than 78.1 mm. Choose rings with 78.1 mm inner diameter and your wheel’s outer bore.

• Will 17 inch wheels clear my brakes?

  Brake packages can vary. The calculator helps with overall diameter, but you must physically confirm barrel and spoke clearance over the calipers with a test fit.

• What tire pressure and lug torque should I use?

  Use the tire pressures and torque specification from the driver door placard and your owner’s manual. Do not guess values.

• Can I keep my factory TPMS with new wheels?

  Yes. Transfer your sensors or use compatible replacements and complete the TPMS relearn procedure for your vehicle.
