2020 Audi Q7 Wheel Interchange

2020 Audi Q7 Wheel Fitment Guide

Known OEM Fitment For 2020 Audi Q7

The following factory specifications are provided for at least one OEM wheel and tire package on the 2020 Audi Q7. Trims and brake packages can vary, so always verify your exact vehicle configuration with the on‑page calculator and OEM documentation.

If your Q7 was delivered with different wheel or tire sizes from the factory, use your door jamb sticker, owner’s manual, or dealer build sheet to confirm specs, then set those as the baseline in the calculator before comparing any upgrades.

How To Use The Wheel Interchange Calculator

• Set Installed on (your vehicle) to 2020 Audi Q7 and confirm the OEM baseline matches your vehicle. If it does not, enter your actual stock sizes from the tire sidewall and wheel markings.
• Choose Wheels from (donor vehicle) to compare a different vehicle or wheel, or use Custom wheel size to try an aftermarket configuration. You can adjust rim diameter, width, and offset. Use Custom tire size to change section width and aspect ratio. The tool updates the total tire diameter automatically when rim diameter changes.
• Check inner clearance. The calculator shows how much closer the inner wheel edge moves toward the strut and suspension. Positive values increase clearance, negative values reduce it. You must maintain adequate clearance under full lock and compression.
• Check outer poke. The tool shows how far the outer edge will move toward the fender. Excess poke risks rubbing the fender or liners. Consider alignment settings and suspension travel.
• Verify overall tire diameter change. Keep total tire diameter close to stock to protect ABS, speedometer accuracy, and driveline components. As a general guideline, limit total diameter change to about plus or minus 3 percent unless you have confirmed calibration options.
• Confirm load index and speed rating. Any replacement tire must meet or exceed the OEM load index and speed rating shown on your vehicle’s tire placard.
• Record final specs. Before ordering, note the exact wheel width, diameter, offset, bolt pattern 5x112, center bore 66.5 mm or larger with hub rings, and thread size M14 x 1.5 with the correct seat type specified by Audi for your fasteners.

Fitment Checklist Before You Buy

• Bolt pattern 5x112 matches exactly.
• Center bore is 66.5 mm. If the wheel bore is larger, plan for hub-centric rings sized to 66.5 mm at the hub and the wheel’s larger bore on the outer side. Do not use a wheel with a smaller bore than 66.5 mm.
• Thread size is M14 x 1.5. Verify fastener seat type for your application cone or ball seat and correct length, especially if using spacers. Do not assume seat type.
• Offset and width clear suspension and fenders. Use the calculator to confirm inner clearance and outer poke. Consider brake caliper shape and size. Physical test-fit is recommended.
• Tire load index and speed rating meet or exceed the door placard. Never downrate load capacity on a heavy SUV.
• TPMS compatibility. Reuse or program sensors that are compatible with the 2020 Audi Q7 system.
• Spacer use. If spacers are required, use hub-centric spacers with appropriate extended M14 x 1.5 hardware and verify thread engagement per OEM guidance.
• Overall diameter within target. Keep overall tire diameter close to stock unless you have confirmed calibration and clearance.

Plus Sizing And Common Upgrades

The calculator lets you explore plus sizes like larger diameter wheels with lower-profile tires while keeping overall diameter close to stock. The values below are not guaranteed to fit all trims or brake packages on the 2020 Q7. Treat them as examples to test in the calculator, then verify clearances and ratings.

• Example plus-1 concept: Move from 19x8.5 ET28 to a 20 inch wheel of appropriate width and offset. Use the calculator to pair a lower-profile tire so overall diameter stays near stock and check inner and outer clearance changes.
• Example wider fitment concept: Keep 19 inch diameter but increase width. Use offsets that maintain inner clearance to the strut while avoiding excessive poke. Confirm fender liner clearance at full lock and compression.
• Staggered setups are generally not recommended for all-wheel drive unless diameter and rolling circumference remain equal front to rear within tight tolerance. Always verify with OEM guidance.
• If you plan winter wheels, a narrower tire can improve snow traction. Use the calculator to confirm diameter, brake clearance, and load index.

Because the Q7 may have different brake packages by trim or option, do not finalize any upgrade without a physical test-fit or a verified brake template match from the wheel manufacturer.

Installation Tips

• Work on a cool vehicle parked on level ground. Chock wheels and use jack stands at the proper lift points. Do not rely on a jack alone.
• Clean hub faces and wheel mounting pads. Remove rust and debris so the wheel seats flush. A thin film of anti-seize on the hub center can help prevent sticking. Keep threads clean and dry unless the OEM specifies otherwise.
• If using hub-centric rings, install them snugly in the wheel bore so the wheel centers on the Q7’s 66.5 mm hub.
• Hand start all fasteners to avoid cross-threading. Tighten in a star pattern in stages with a calibrated torque wrench to the specification in your owner’s manual. Do not use an impact gun to final torque.
• Re-torque after 50 to 100 miles of driving.
• Verify tire rotation direction and that TPMS sensors are installed and programmed as required.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• Wheel hanger guide pin M14x1.5 to help center heavy SUV wheels
• Hub-centric rings 66.5 mm to your wheel bore if the aftermarket wheel bore is larger than 66.5 mm
• TPMS programming tool compatible with your sensors

FAQs

• What is the bolt pattern on the 2020 Audi Q7?

  The known bolt pattern is 5x112. Verify any wheel is drilled for 5x112 before purchase.

• What center bore do I need?

  The hub bore is 66.5 mm. Wheels with a larger bore can be made hub-centric with rings sized to 66.5 mm on the hub side. Do not use a wheel with a bore smaller than 66.5 mm.

• What is the thread size and do I need special lug hardware?

  The thread size is M14 x 1.5. You must also match the correct seat type cone or ball and length for your application. Check your owner’s manual or OEM parts information.

• Will 20 inch or larger wheels fit my Q7?

  Fitment can vary by trim, suspension, and brake package. Use the calculator to compare inner clearance, poke, and overall diameter against your exact OEM setup, then confirm with a test-fit or wheel maker brake template.

• What offset should I use with wider wheels?

  There is no single offset that works for all widths and brake packages. Use the calculator to see how changes in width and offset affect inner clearance and outer poke relative to the OEM baseline listed above.

• Do I need spacers?

  Only if required to clear brakes or suspension. If used, choose hub-centric spacers and the correct extended M14 x 1.5 hardware with proper seat type and thread engagement per OEM guidance.

• Will my TPMS work with new wheels?

  Yes, if you transfer compatible sensors or install new sensors that can be programmed to the 2020 Q7. Follow the sensor and vehicle programming procedure in the service information.

• What tire load index do I need?

  Use the tire placard on your driver door jamb to find the required load index and speed rating. Any replacement tire must meet or exceed those ratings.

• How close should overall tire diameter be to stock?

  Keep it close to stock to protect ABS and speedometer function. As a general guideline, limit changes to about plus or minus 3 percent unless the vehicle can be recalibrated and physical clearances have been confirmed.

Always verify final fitment with the calculator on wheelinterchange.com and confirm clearances with a physical test-fit. If a specification is not listed here for your exact trim, consult the Audi owner’s manual, service information, or your dealer.
