2009 Chevrolet Silverado 1500 Wheel Interchange

2009 Chevrolet Silverado 1500 Wheel Fitment Guide

This page compiles verified wheel and tire specs observed on select 2009 Chevrolet Silverado 1500 factory packages. Because Silverado 1500 trims and option codes vary, treat the values below as known data points rather than a complete list. Always confirm your exact OEM sizes from the driver door placard and the on-page calculator before purchasing wheels or tires.

Known OEM Fitment For 2009 Chevrolet Silverado 1500

Note: The wheel and tire examples above come from different factory packages. Your truck may have 17, 18, or 20 inch OEM equipment depending on trim and options. Verify your exact stock sizes on your tire placard and enter them into the calculator for precise comparisons.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor setup to your Silverado and also test custom wheel and tire sizes.

• Set Installed on to 2009 Chevrolet Silverado 1500, then enter the exact OEM wheel and tire sizes from your door placard. If you only know one of the examples above, you can start with that and refine as needed.
• For donor wheels, either select a donor vehicle or choose Custom wheel size to enter rim diameter, width, and offset. If you change rim diameter, also set a matching tire size so overall tire diameter is realistic.
• Review the comparison outputs. Focus on inner clearance to the suspension and brakes, outer poke relative to the fender, and tire diameter change. Caliper shape is not modeled, so always test fit for brake clearance before mounting tires.
• Speedometer and gearing are affected by tire diameter. Many owners target a small diameter change for street use. Use the calculator’s tire diameter readout to fine tune.
• If you run spacers or hub-centric rings, include their effect. Spacers effectively reduce offset, which increases outer poke and reduces inner clearance.

Fitment Checklist Before You Buy

• Bolt pattern must match exactly: 6x139.7.
• Center bore must be 78.1 mm or larger. If the wheel bore is larger, use quality hub-centric rings sized 78.1 mm to your wheel bore.
• Thread size is M14 x 1.5. Match lug nuts to the wheel’s seat type and ensure proper thread engagement. Do not force mismatched threads.
• Offset and backspacing: Compare your current wheel to the new wheel in the calculator. The known OEM example is 20x8.5 ET 31 mm with 5.47 in backspacing. Large changes can cause fender contact or inner interference.
• Brake clearance: Spoke design and barrel shape vary. Test fit the bare wheel to confirm caliper clearance before mounting tires.
• Tire diameter and width: Check full-lock steering and suspension compression. Watch the upper control arm, sway bar, pinch weld, fender liner, and mud flaps.
• Load rating: Wheel and tire load ratings must meet or exceed your truck’s axle weight ratings.
• TPMS: Plan for compatible sensors or sensor swaps. Relearn procedure is required after changes.
• Stud length and lug engagement: Aim for full nut engagement at least equal to the stud diameter. If using spacers, verify you still have adequate thread engagement.
• Spacers: Use hub-centric, high quality spacers only. Add spacer thickness into your offset calculation.
• Chains and winter use: Verify inner and outer clearances with your intended chain size if applicable.

Plus Sizing And Common Upgrades

Plus sizing trades sidewall height for larger rim diameter while keeping overall tire diameter close to stock to maintain speedometer accuracy and clearance. For example, a 245/70R17 tire has an overall diameter of about 30.5 in. If you move to a larger wheel, use the calculator to choose a tire size that keeps the diameter near your stock target, then compare inner and outer clearances by adjusting wheel width and offset.

• Starting from a 17 inch package like 245/70R17, try 18 or 20 inch options in the calculator and tune tire aspect ratio until overall diameter remains near stock.
• If your truck already has the OEM 20 x 8.5 ET 31 mm wheels, you can use the calculator to evaluate alternative tire widths while watching for fender and UCA clearance.
• Leveling kits and lift kits change clearance. Recheck fitment after any suspension change.

Installation Tips

• Test fit a bare wheel on the front and rear hubs to confirm center bore fit and brake clearance.
• Remove rotor retention clips if present and not compatible with the new wheel’s mounting face.
• Clean the hub face and center pilot with a wire brush. A thin film of anti-seize on the hub face can help prevent future corrosion. Do not apply lubricant to studs or lug nut seats.
• If using hub-centric rings, seat them fully on the hub before installing the wheel.
• Hand start all lug nuts, then snug in a star pattern. Final torque to the OEM specification for your trim using a calibrated torque wrench.
• Re-torque after 50 to 100 miles of driving.
• Perform a TPMS relearn and set tire pressures to the door placard unless your tire load index requires a different pressure. Road test and check for rubbing at full lock and over bumps.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• GM TPMS relearn tool
• Wire brush or hub cleaning tool
• M14 x 1.5 thread chaser

FAQs

What is the bolt pattern on the 2009 Silverado 1500?
6x139.7.

What center bore do I need?
78.1 mm hub bore. If your aftermarket wheel has a larger bore, use hub-centric rings sized 78.1 mm to the wheel bore.

What is the lug nut thread size?
M14 x 1.5. Match the lug nut seat to your wheel design and do not mix thread pitches.

Did some 2009 Silverado 1500 trucks come with 20 inch wheels?
Yes. A known OEM example is 20 x 8.5 in with ET 31 mm and 5.47 in backspacing. Other trims used smaller diameters. Verify your truck’s exact package on the door placard.

I see 245/70R17 listed. Will that fit my truck?
245/70R17 is a known factory tire size example for certain packages and is about 30.5 in in overall diameter. Check your placard and use the calculator to confirm against your specific suspension and wheel setup.

What offset should I choose for aftermarket wheels?
Start by entering your current wheel size and the new wheel’s width into the calculator. Compare inner clearance and outer poke. The known OEM example offset is ET 31 mm on an 8.5 in wheel. Stay close to stock geometry for easiest fitment and confirm with a test fit.

Do I need hub-centric rings?
If the aftermarket wheel’s center bore is larger than 78.1 mm, use rings to center the wheel on the hub. If the bore is exactly 78.1 mm, rings are not used.

What torque should I use on the lug nuts?
Follow the OEM torque spec for your exact trim. Refer to the owner’s manual or a dealer service source. Torque in a star pattern and re-torque after 50 to 100 miles.

Will a leveling kit change what fits?
Yes. Ride height and suspension geometry affect inner and outer clearance. Recheck all measurements in the calculator and perform a physical test fit after any suspension change.
