Known OEM Fitment For 2012 Chevrolet Silverado 1500

The Silverado 1500 had multiple factory wheel and tire packages in 2012. The values below are confirmed OEM specs for at least one configuration. They may not be paired together and may vary by trim, option package, and brake size. Always verify your exact truck’s specs with the on-page calculator and OEM sources before purchasing.

Notes:

• The 20x8.5 ET31 wheel and the 245/70R17 tire reflect different stock packages that existed in 2012. Do not assume they came together.
• Other OEM sizes may exist. Confirm your trim’s original size using your owner’s manual, door jamb tire label, or by checking with a Chevrolet dealer.

How To Use The Wheel Interchange Calculator

The calculator on this page compares “Wheels from (donor vehicle)” to “Installed on (your vehicle)” and lets you try custom sizes safely. Here is the quick process:

• Select your 2012 Chevrolet Silverado 1500 as “Installed on”.
• Choose a “Wheels from” donor vehicle if you are considering a direct swap, or leave it blank if you are testing aftermarket sizes.
• Use “Custom wheel size” to change rim diameter, width, and offset. The tool shows inner clearance to suspension/brakes and outer poke vs your known OEM baseline.
• Use “Custom tire size” to set section width and aspect ratio. Changing rim diameter updates overall tire diameter in the comparison.
• Keep overall tire diameter close to stock to protect speedometer and ABS logic. The tool highlights changes so you can aim for minimal variance.
• Print or save the results and measure your truck for clearance where the tool shows the largest changes.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 6x139.7 to match the Silverado 1500 hubs.
• Center bore: The truck’s hub is 78.1 mm. Wheels must have a 78.1 mm bore or larger. If larger, use quality hub-centric rings sized to 78.1 mm.
• Thread size and nuts: M14 x 1.5 studs. Use compatible lug nuts that match both the thread and the wheel’s seat style per the wheel manufacturer. Do not mix seat types.
• Offset and backspacing: Use the calculator to compare your new wheel’s offset and width to the known OEM baseline of 20x8.5 ET31 and 5.47 in backspacing. Verify inner clearance to the knuckle, UCA, sway bar, and brake caliper, and check outer fender clearance.
• Brake clearance: Test-fit one front wheel to ensure spoke and barrel clear the calipers.
• Tire diameter and width: Use the calculator to keep overall diameter near stock and to avoid rubbing at full lock and compression.
• Load rating: Ensure wheel and tire load ratings meet or exceed your truck’s GAWR and intended use, especially for towing or hauling.
• TPMS: 2012 models use TPMS. Make sure sensors are compatible and be prepared to perform a relearn after installation.
• Spacers: If using spacers, choose hub-centric designs that match 78.1 mm and ensure adequate stud engagement. Follow local regulations.

Plus Sizing And Common Upgrades

General guidance for safe upsizing using the calculator:

• Overall diameter: Based on the known OEM tire 245/70R17, overall diameter is about 30.5 in. Aim to keep new tire diameter within a small percent of this to maintain speedometer accuracy. The calculator will show the difference.
• Width vs offset: If you go wider than the known OEM 8.5 in wheel, reduce positive offset to keep inner clearance similar. If you go narrower, more positive offset can maintain inner clearance. Use the calculator to visualize inner and outer changes.
• 20 in wheels: A 20x8.5 ET31 wheel exists as an OEM configuration for this truck. If you choose a different width or offset in 20 in, verify clearances in the tool.
• Ride and handling: Larger diameter wheels generally require lower profile tires. Expect firmer ride and increased impact sensitivity. Confirm load index and speed rating meet your needs.

Because trims and brake packages vary, do not assume another Silverado’s setup will fit yours. Always confirm with measurements and the calculator, and verify against OEM documentation.

Installation Tips

• Park on level ground, chock rear wheels, set parking brake. Use rated jack stands at approved frame points.
• Clean hub faces and wheel mounting pads until bare metal to prevent runout. Lightly wire-brush rusty studs.
• Dry-fit one front wheel and rotate to check caliper, knuckle, and fender liner clearance at full lock.
• If using hub-centric rings for aftermarket wheels, install them fully seated in the wheel bore before mounting.
• Hand-thread M14x1.5 lug nuts to avoid cross-threading. Confirm correct seat style for your wheels.
• Tighten in a star pattern. Use a calibrated torque wrench to finish tightening to the specification in your owner’s manual. Do not rely solely on an impact gun.
• Re-torque after the first short drive and again after a few heat cycles. Recheck torque any time the wheel is removed.
• Perform TPMS relearn if sensors were changed or moved. Follow the procedure in your owner’s manual.
• Get a professional alignment after changing wheel or tire sizes to protect tire wear and handling.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• 1/2 inch breaker bar
• Metric impact socket set
• Anti-seize compound

FAQs

What is the bolt pattern on the 2012 Silverado 1500?
6x139.7.

What center bore does my truck use?
78.1 mm. If your aftermarket wheel has a larger bore, use hub-centric rings sized to 78.1 mm.

Do 20 inch wheels fit a 2012 Silverado 1500?
A 20x8.5 wheel with ET 31 mm is a known OEM configuration for this model year. If you choose a different width or offset, use the calculator to confirm inner and outer clearance.

What is the stock lug nut thread size?
M14 x 1.5. Verify the correct seat style for your specific wheels and follow the torque spec in the owner’s manual.

Will wheels from another 6x139.7 vehicle fit?
Matching bolt pattern is only the first step. You must also match or accommodate center bore, verify offset and backspacing clearances, ensure proper lug nut seat style, and confirm brake and hub contact. Use the calculator and test-fit to be sure.

What is the stock backspacing?
5.47 in on the known OEM 20x8.5 ET31 wheel. Use this as a baseline in the calculator when comparing new wheels.

How close should my new tire’s overall diameter be to stock?
Keep it close to your baseline to protect speedometer and ABS function. Using the provided 245/70R17 as a reference, overall diameter is about 30.5 in. The calculator will show the variance for any size you try.

Do I need new TPMS sensors?
If reusing your original sensors and the new wheels accept them, you may not need new ones. If you install new sensors, ensure compatibility with a 2012 Silverado 1500 and perform a relearn per the owner’s manual.
