2016 Audi A5 Wheel Fitment - Specs, swaps, and safe upgrades

You are looking at wheel and tire data specific to the 2016 Audi A5. The aim is clean, safe installs with no rubbing, vibration, or hardware issues.

tl;dr

  • Core specs: 5x112 bolt pattern, 66.6 mm hub, M14x1.5 wheel bolts.
  • Factory sizes vary by trim and package. Confirm yours before buying.
  • This page shows an OEM wheel example and an OEM tire example that do not match each other, which indicates multiple factory setups.
  • Use the calculator to compare donor wheels to your A5. Adjust width, offset, and tire to check clearances.

Recommendation

Work from verified baseline data, then preview changes with the calculator before you buy.

  • Confirm your exact factory size from the door placard and owner info. Trims differ.
  • Log the hard points: 5x112, hub 66.6 mm, M14x1.5 bolts. These must match.
  • Use hub-centric wheels at 66.6 mm, or quality rings if the wheel bore is larger.
  • Keep wheel offset changes modest, and check inner and outer clearance in the calculator.
  • Keep overall tire diameter close to stock to protect ABS, speedometer, and drivetrain.
  • Test-fit on the car before mounting tires when possible, especially with big brake packages.

Impact

Here is how each change affects the 2016 A5 in practice.

  • Diameter - Alters speedometer and gearing feel. The calculator updates tire diameter when you change rim diameter so you can see the delta.
  • Width - Adds inner or outer clearance load. Wider wheels push closer to fenders or suspension depending on offset.
  • Offset - Shifts scrub and bearing load. Small changes matter at the fender lip and strut.
  • Tire profile - Sidewall height changes ride, rim protection, and rub risk on compression.
  • Hub fit - 66.6 mm keeps the wheel centered. Larger bores need rings. Smaller bores will not fit.
  • Hardware - M14x1.5 bolts must seat correctly and achieve full thread engagement.

Risks

  • Brake clearance - Spoke design and barrel shape can foul calipers. Do a visual and template check if unsure.
  • Offset extremes - Too low can poke and rub fenders. Too high can hit struts or control arms.
  • Hub mismatch - Running off-center without rings can cause vibration and stud or bolt stress.
  • Hardware mismatch - Wrong bolt seat type or length can loosen or damage hubs. Verify with the wheel maker.
  • Undersized tires - Stretch and curb damage risk go up. Sidewalls protect rims and absorb impact.
  • AWD concerns - Many 2016 A5 models are Quattro. Keep rolling diameters matched across all four tires.

Using the calculator on this page

The calculator compares Wheels from a donor vehicle against Installed on your vehicle. It also lets you try Custom wheel size and Custom tire size.

  • Start by selecting a donor vehicle with wheels you are considering.
  • Set Installed on to 2016 Audi A5.
  • Enter your custom wheel width, diameter, and offset if you are not using stock sizes.
  • Enter your custom tire width and aspect ratio if needed. When you change rim diameter, the calculator updates the compared tire diameter so you can track the overall change.
  • Review inner clearance, outer poke, and diameter change outputs. Aim for small, manageable changes.

Next actions

Checklist and gotchas for a clean install.

  • Confirm your factory size from the driver door placard and owner information.
  • Record 5x112, 66.6 mm hub, and M14x1.5 hardware for all purchases.
  • Run your candidate wheels and tires through the calculator. Check both inner and outer clearance.
  • If the wheel bore is larger than 66.6 mm, add hub-centric rings sized to 66.6 mm.
  • Verify bolt seat style and length with the wheel manufacturer before buying hardware.
  • Test-fit a bare wheel on the car to confirm hub, brake, and spoke clearance.
  • Torque fasteners to the Audi spec from your manual, in a star pattern, on clean threads.
  • Re-torque after 50-100 miles. Listen and feel for any vibration.
