OEM wheel and tire fitment specs for the 2015 Audi SQ5, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2015 Audi SQ5, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 66.6 mm vs trim range 66.5–66.5 mm. Interchange below does not treat this as an unqualified match.

Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2015 Audi SQ5. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 188 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Center-bore records disagree (target year-level hub 66.6 mm vs trim range 66.5–66.5 mm; donor year-level hub 66.6 mm vs trim range 66.5–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved.
Dataset suggestionWheel spacer ≈ 13.85 mm – not a verified installation requirement.
A spacer of about 13.85 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 13.85 mm farther inward than the mid OEM package.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Center-bore records disagree (target year-level hub 66.6 mm vs trim range 66.5–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -5.5 mm, inner change 5.5 mm. This uses aggregated width/offset ranges, not a specific wheel.

How To Use The Wheel Interchange Calculator
Open the calculator on this page. In Wheels from set your donor wheel and tire or a known package you want to compare. In Installed on select 2015 Audi SQ5.
Use Custom wheel size to change rim diameter, width, and offset. Use Custom tire size to change section width and aspect ratio.
When you change rim diameter, the tool updates tire diameter in the comparison so you can track total height and speedometer impact.
Review inner clearance vs strut and brake, and outer poke vs fender. The calculator shows how far the new setup moves inward or outward relative to the OEM baseline above.
Aim to keep total tire diameter close to stock to protect ABS, stability control, gearing, and speedometer. Many installers try to stay within about 3 percent, but follow manufacturer guidance and your local regulations.
Check brake caliper clearance. Visualize spoke and barrel room with the calculator and physically test-fit when possible.
If center bore on the new wheel is larger than 66.6 mm, plan on hub-centric rings to keep the wheel centered. If it is smaller than 66.6 mm, the wheel will not seat.
Save your comparison and measurements before ordering. If any value is unclear for your trim, verify with the VIN-specific parts catalog or an Audi dealer.
Fitment Checklist Before You Buy
Bolt pattern: Must be 5x112.
Center bore: Wheel must be 66.6 mm or larger with proper hub-centric rings to 66.6 mm. Smaller bores will not fit.
Thread size and hardware: M14 x 1.5. Hardware seat style and length vary by wheel manufacturer. Match the seat type and shank length to the wheel maker’s instructions. Do not assume OEM hardware fits every aftermarket wheel.
Offset and backspacing: Compare to the OEM baseline 8.5Jx20 ET33 and 5.55 in backspacing. Use the calculator to ensure inner clearance to strut and brake and to control outer poke under the fender.
Brake clearance: The SQ5 uses larger performance brakes. Confirm spoke-to-caliper and barrel clearance. Template checks and test fits are recommended.
Tire diameter and load rating: Keep total diameter close to stock and ensure tire and wheel load ratings meet or exceed the vehicle’s GAWR specifications.
TPMS: Follow the owner’s manual for TPMS type and reset or relearn procedure for your market and trim.
Speedometer variance: Review the calculator’s delta and confirm it is acceptable for your use and local laws.
Return policy: If buying online, confirm you can return or exchange if the test fit is not acceptable.
Plus Sizing And Common Upgrades
Plus sizing increases wheel diameter or width to change appearance and handling. On the 2015 Audi SQ5, success depends on brake clearance, offset, and tire diameter. Use the calculator to model these common scenarios:
Wider same-diameter setup: Keep 20 in diameter but adjust width and offset. Check inner clearance and fender poke.
+1 diameter: Move to a larger rim size. Choose a tire with a lower aspect ratio that keeps overall diameter near stock.
-1 diameter or winter setup: Smaller diameter wheels may improve ride and winter tire availability, but must clear the front brakes. Always verify caliper and barrel clearance.
Tire diameter formula used by the calculator: total diameter = wheel diameter in mm plus 2 times section width times aspect ratio. Use this to sanity check your choices, then rely on the calculator for exact differences against OEM.
Installation Tips
Clean the hub face and the wheel mounting pad to bare metal. Remove rust and debris to prevent runout.
Dry-fit one front and one rear before mounting tires when possible. Verify caliper and suspension clearance throughout steering lock and suspension travel.
If your vehicle uses lug bolts rather than studs and nuts, use a wheel hanger guide pin to support the wheel during installation.
Use only hardware that matches the wheel’s seat type and required length. Do not mix cone seat and ball seat hardware.
Tighten in a star pattern by hand first, then torque to the factory specification from the owner’s manual. Re-torque after 50 to 100 miles.
Do not lubricate fastener threads unless the manufacturer explicitly instructs it. A thin film of anti-seize on the hub pilot can help future removal, but keep it off the brake rotor and friction surfaces.
Set tire pressures to the label in the driver door jamb unless your tire professional specifies otherwise for the new size and load rating.
5x112. The wheel must have 5 lug holes on a 112 mm circle.
What center bore do I need
66.6 mm. Wheels with a larger bore can be used with 66.6 mm hub-centric rings. Wheels with a smaller bore will not fit.
Can I reuse my factory wheel bolts with aftermarket wheels
Only if the seat type, length, and thread match the wheel maker’s requirements. Many aftermarket wheels require different seat geometry. Confirm with the wheel manufacturer and your installer.
What offset should I choose
The known OEM reference is ET33 on an 8.5 in wide 20 in wheel. Use the calculator to model inner clearance to the strut and brakes and outer poke relative to the fender for your chosen width. Do not assume a single offset works for every width.
Will a different diameter tire affect my speedometer
Yes. Changing overall tire diameter changes indicated speed and can affect ABS and stability systems. Use the calculator to compare total diameter to stock and keep variance minimal as allowed by your local regulations and Audi guidance.
Do I need spacers
Only if they are required to clear brakes or suspension after verifying with the calculator and a test-fit. Spacers must be high quality, hub-centric to 66.6 mm, and used with the correct extended hardware. Improper spacers can cause vibration and fastener failure.
What is the correct torque for the wheel fasteners
Torque values can vary by model and market. Do not guess. Use the torque specification in your owner’s manual or Audi service documentation for your VIN.
Will smaller diameter winter wheels fit over the SQ5 brakes
It depends on your brake package. The calculator can help model barrel and spoke clearance, but you must also confirm physically with a test-fit or a brake template from the wheel manufacturer.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
