2008 Chevrolet Suburban 1500 Wheel Interchange

2008 Chevrolet Suburban 1500 Wheel Fitment Guide

Known OEM Fitment For 2008 Chevrolet Suburban 1500

These specifications are reported for the 2008 Chevrolet Suburban 1500. Packages varied by trim. If a value on your vehicle differs, verify it on your tire placard, the owner manual, or with a GM dealer using your VIN, then confirm with the calculator on this page.

Notes:

• Multiple OEM wheel and tire packages existed in 2008. The values above may come from different trims. Confirm what your Suburban 1500 actually has before comparing new wheels.
• Use your door jamb tire placard to confirm the factory size and load rating, then match the calculator inputs to your vehicle.

How To Use The Wheel Interchange Calculator

• Open the calculator on this page and select a donor vehicle or enter a custom wheel size for the Wheels from side.
• Set Installed on to 2008 Chevrolet Suburban 1500 so the tool uses the specs for your SUV.
• To try an aftermarket setup, use Custom wheel size to enter rim diameter, width, and offset. Use Custom tire size to set section width and aspect ratio.
• Review inner clearance and outer poke changes. Inner clearance tells you how close the wheel and tire move toward the strut, upper control arm, and inner fender. Outer poke shows how far they move toward the fender lip.
• Changing rim diameter updates tire diameter in the comparison. Keep overall tire diameter close to stock to protect ride, ABS, and speedometer accuracy.
• If your current vehicle does not match the reported values above, enter your actual factory size from the tire placard, then compare options against that baseline.

Fitment Checklist Before You Buy

• Bolt pattern: Wheel must be 6x139.7.
• Center bore: Hub bore is 78.1 mm. If an aftermarket wheel has a larger bore, plan for hub-centric rings sized to 78.1 mm.
• Thread size: Lug nuts must match M14 x 1.5 studs. Confirm seat type matches the wheel design.
• Offset and width: Use the calculator to keep inner clearance safe and avoid excessive poke. Physically measure brake caliper and suspension clearance on your vehicle.
• Brake clearance: Spoke shape and barrel design matter. Test fit a front wheel to ensure caliper clearance.
• Tire diameter and load index: Match or exceed the OEM load rating. Keep overall diameter close to stock to limit speedometer error.
• TPMS: 2008 models use TPMS. Verify sensor compatibility for your VIN and that the new wheels accept the sensors.
• Spare and towing: Make sure the spare strategy still works and that any changes do not reduce tow or payload limits.

Plus Sizing And Common Upgrades

The calculator supports plus sizing. A common goal is to keep overall tire diameter close to stock while changing rim diameter. For reference, a 265/70R17 tire is approximately 31.6 inches in overall diameter. If you choose a larger rim, select a tire size that stays near this diameter to protect drivability and gearing feel.

• Plus 1 or Plus 2: Increase rim diameter and choose a lower-profile tire so overall diameter remains near 31.6 inches. Use the calculator to confirm.
• Wider stance: Small increases in width can improve grip. Use the calculator to check both inner clearance and outer poke, and inspect fender and liner clearance at full lock and full bump.
• Off-road setups: Taller sidewalls help off-road, but confirm clearance at full suspension compression and with chains if you use them.
• Do not assume any size fits. Use the calculator and a test fit before buying a full set.

Installation Tips

• Work on a cool vehicle parked on level ground. Support with jack stands at the frame and chock the wheels.
• Remove wheels, then clean hub faces and rotor hats with a wire brush. Any rust or debris can cause vibration.
• If aftermarket wheels have a larger center bore, install hub-centric rings to 78.1 mm. Dry fit the ring and wheel and check for flush mounting.
• Transfer or install TPMS sensors per the wheel manufacturer instructions. Perform the GM TPMS relearn after installation following your owner manual.
• Hand start all lug nuts on the M14 x 1.5 studs. Snug in a star pattern, then torque to the value in your owner manual in 2 to 3 stages.
• After a short test drive, recheck torque. Re-torque again after 50 to 100 miles.
• If you changed overall tire diameter, use the calculator to estimate speedometer error and consider calibration if needed.

Tools And Helpful Supplies

• 1/2 inch torque wrench
• M14 x 1.5 lug nuts
• 78.1 mm hub-centric rings
• Heavy duty jack stands

FAQs

• What is the bolt pattern on a 2008 Chevrolet Suburban 1500

  6x139.7.

• What center bore do I need

  78.1 mm. If a wheel has a larger bore, use hub-centric rings sized to 78.1 mm. If it is smaller, it will not fit without machining.

• What is the thread size for the lug nuts

  M14 x 1.5. Verify the seat style that matches your wheel design before purchasing lug nuts.

• Were 20 inch wheels available on 2008 Suburban 1500

  A 20 x 8.5 wheel with ET 31 mm and 5.47 in backspacing is reported for some trims. Packages varied. Confirm your original equipment with the tire placard or a GM dealer, then compare in the calculator.

• Is 265/70R17 an OEM tire size

  265/70R17 is reported for some trims. Verify against your door jamb placard. Use the calculator to compare other sizes to your actual OEM baseline.

• What offset should I choose if I go wider

  Offset needs depend on wheel width, brake clearance, and bodywork. Use the calculator to see inner clearance and outer poke changes, then test fit to confirm there is no rubbing at full lock and full compression.

• Do I need new TPMS sensors

  2008 models use TPMS. You can transfer compatible sensors or buy new ones that match your VIN and wheel type. Perform the TPMS relearn after installation per the owner manual.

• What is the correct lug nut torque

  Consult your owner manual or OEM service information for the exact torque. Do not guess. Torque in a star pattern and re-torque after 50 to 100 miles.
