2020 Audi SQ5 Wheel Interchange

Goal

You want to know which donor wheels and tires will safely fit a 2020 Audi SQ5. The common stumbling blocks are bolt pattern, center bore, offset, width, and tire diameter. A small mismatch can cause vibration, rubbing, or brake interference. The goal here is to use the on-page calculator and a few OEM checkpoints to make a confident, safe choice under real-world constraints.

Prerequisites

Known OEM fitment for the 2020 Audi SQ5, as provided on this page:

Assumption: Actual factory equipment can differ by package. The mix of 19 inch rim and 255/45R20 tire in the feed suggests multiple trims. Treat the table as a starting point, not a single spec for all 2020 SQ5s.

How to confirm your baseline:

• Door-jamb tire placard lists the OEM tire size for your VIN.
• Wheel back face usually shows size and offset stamps, for example 20x8.5 ET34.
• OEM parts catalog or dealer can validate by VIN.

Helpful tools for installation and checks:

• 1/2 inch drive torque wrench
• Wheel hanger guide pin M14x1.5
• Hub-centric rings 66.5 mm to your wheel bore

Step by step

1) Set your baseline in the calculator

In the Installed on field, choose 2020 Audi SQ5. If your vehicle shows multiple OEM sizes, begin with the tire size on your door placard. If your wheel stamps do not match the table above, adjust the Custom wheel size to your verified OEM dimensions so the comparison starts from your true baseline.

2) Enter the donor wheel

In the Wheels from field, select the donor vehicle to pull its specs. If you do not see it listed, use Custom wheel size to enter rim diameter, width, and offset, then set Custom tire size if you plan to move the donor tires as well.

3) Check core fitment rules

• Bolt pattern must be 5x112. No adapter is recommended unless you model its thickness as a spacer and source proper hardware.
• Center bore on the SQ5 hub is 66.5 mm. A wheel with a larger bore can fit with hub-centric rings. A smaller bore will not fit the hub.
• Thread size is M14x1.5. Confirm the seat type that your wheel requires. Audi OEM commonly uses ball seat. Many aftermarket wheels use cone seat. Match the bolt seat to the wheel.

4) Manage diameter and gearing effects

Use the calculator’s tire comparison to keep overall diameter close to stock. Recommended: target within about 1 to 2 percent. Try to avoid beyond roughly 3 percent to limit speedometer error and gearing load. When you change rim diameter, set a tire size that maintains overall diameter.

5) Control clearance with width and offset

Use the inner clearance and outer poke readouts:

• Inner clearance: keep several millimeters away from strut, spring perch, and liner. I look for at least 3 to 5 mm as a working minimum, more if bushings are soft.
• Outer poke: ensure fender coverage through compression and steering. The calculator shows how far the new setup moves outward.

If you widen the rim, offset often needs to increase numerically to pull the wheel inward and preserve fender clearance. The calculator will also show backspacing. Backspacing is derived from width and offset. Validation is easier there than relying on a static figure.

6) Account for brakes and hardware

• Brake caliper clearance: face design matters. Even with the same offset, spoke shape can change clearance. If uncertain, test fit with no tire first, or measure using a straightedge from hub face across the caliper and compare to the wheel’s spoke drop.
• Spacers: if you add a spacer to clear brakes, reduce effective offset by the spacer thickness in the calculator and plan for longer bolts with the correct seat.
• Hub-centric rings: if the wheel bore is larger than 66.5 mm, add rings sized to the wheel bore to prevent vibration.

Validation

Before driving distance, validate physically:

• Hand-spin the wheel on the hub. It should rotate freely without liner contact.
• Lower the vehicle and check fender clearance at straight ahead and full lock both directions.
• Load the suspension. A curb ramp or careful jack under the control arm compresses the corner to simulate bumps.
• Verify thread engagement. For M14x1.5, I look for a solid number of turns that equals the bolt diameter in threads. Count actual turns during install.
• Road test at 30 to
