2014 Audi SQ5 Wheel Fitment and Interchange Guide | wheelinterchange.com

tl;dr

• Known OEM: 5x112 bolt pattern, 66.6 mm center bore, M14 x 1.5 threads.
• OEM wheel: 20 x 8.5 ET33, backspacing 5.55 in.
• OEM tire: 255/45R20. Overall diameter is about 29.0 in.
• Use the on-page calculator to compare donor wheels to your SQ5.
• Match bolt pattern, keep offset changes small, verify hub bore and brake clearance.
• Use hubcentric rings if the wheel bore is larger than 66.6 mm.

Recommendation

I recommend you start from the OEM baseline above, then use the calculator on this page to compare any donor wheel and tire. Keep bolt pattern identical, hub bore equal to or larger than 66.6 mm, and offset close to OEM. If the donor wheel bore is larger, plan on hubcentric rings. Verify spoke and barrel clearance over the front brakes with a test fit. Keep overall tire diameter close to stock to avoid speedometer and ABS issues. Confirm hardware seat type before installing bolts.

How to use the calculator effectively

• Set Installed on to 2014 Audi SQ5 with the OEM values listed.
• Set Wheels from to your donor vehicle or aftermarket size.
• Adjust Custom wheel size and Custom tire size as needed. The tool updates tire diameter when rim diameter changes.
• Review inner clearance, outer poke, ride height change, and speedometer error. Keep changes modest for predictable handling.

Impact

• Handling and steering: Small offset changes alter scrub radius and steering weight. Closer to ET33 keeps the feel familiar.
• Bearing and suspension load: Larger poke or heavy spacers can increase stress. Keep track width changes conservative.
• Fender and liner clearance: Wider wheels or lower offsets can rub on compression or full lock. Check both front and rear.
• Brakes: The SQ5 uses large front brakes. The wheel’s barrel and spoke shape must clear the caliper. Test fit before mounting tires.
• Speedometer and ABS: Overall diameter changes affect speed reading and systems that rely on wheel speed. Keep diameter close to stock.
• Ride quality: Lower profile tires ride firmer and may increase impact harshness.

Risks

• Incorrect bolt pattern or hardware can cause vibration or loss of clamping force.
• Wrong hub bore without rings can cause vibration at highway speeds.
• Overly aggressive offset or width can cause rubbing and wheel bearing wear.
• Insufficient brake clearance can damage calipers or wheels.
• Mismatched bolt seat type can loosen under load. Verify ball vs cone seat.
• Insufficient tire load index can lead to overheating and failure.

Next actions

1. Baseline your car
   • Confirm your current wheel size and offset markings on the inside of the wheel.
   • Note OEM specs above for the Installed on side of the calculator.
2. Pre-screen donor wheels
   • Bolt pattern must be 5x112.
   • Center bore must be 66.6 mm or larger. Plan hubcentric rings if larger.
   • Offset near ET33 is easiest to fit. Use the calculator to quantify changes.
   • Check the wheel’s load rating meets or exceeds the SQ5’s requirements.
3. Use the calculator
   • Enter donor wheel and tire. Review inner clearance, outer poke, and diameter change.
   • Aim for minimal diameter change to keep speedometer and ABS happy.
4. Test fit for brakes and fenders
   • Front axle first. Spin the wheel by hand and check spoke and barrel clearance to the caliper.
   • Cycle steering lock to lock. Inspect liner and suspension arm clearance.
5. Prepare install hardware
   • Use the correct seat type bolts that match the wheel. Threads are M14 x 1.5.
   • Add hubcentric rings if the wheel bore is larger than 66.6 mm.
   • Spacers only if needed for clearance, with proper extended hardware. Recheck the calculator with spacers added.
6. Install and torque
   • Hand start bolts, snug in a star pattern, then torque to the value in your owner’s manual.
   • Re-torque after 50 to 100 miles. Monitor for vibration.
7. Final checks
   • Verify no rubbing over bumps or at full lock.
   • Check tire load index and pressure. Adjust TPMS or perform relearn per the manual.
   • Schedule an alignment if you changed width or offset.

Gotchas checklist

• Seat type mismatch. Audi OEM wheels often use ball seat. Many aftermarket use cone seat. Match the wheel.
• TPMS type can vary by market. You may need sensors or a relearn. Check your manual.
• Winter setups need clearance for chains and slush. Verify inner clearance margin.
• Do not rely on backspacing alone when changing width. Always evaluate offset with width in the calculator.

If any value on your SQ5 differs by trim or region, confirm it against your owner’s manual and the on-page calculator results. When in doubt, test fit before mounting tires.
