Goal
You want wheels that fit your 2014 Audi R8 safely, without rubbing or vibration. The challenge is that fitment can vary by trim and brake package. This guide shows how to verify the key measurements, use the wheelinterchange.com calculator with confidence, and validate the result on the car.
Prerequisites
Assumptions and constraints
Vehicle: 2014 Audi R8, all trims possible. Some trims may run staggered front and rear sizing.
You will confirm any unknown values using the on-page calculator and OEM sources.
Safety first. Support the car with quality stands on solid ground.
Known 2014 Audi R8 OEM baseline
These values are provided as a reference starting point. Audi offered multiple setups. Rear wheel and tire sizes can differ by trim. Confirm your exact setup before ordering.

Tools and references
Owner’s manual and door-jamb tire label for OEM sizes.
A flashlight to read wheel markings. Offset is usually cast as ETxx inside the wheel.
Check the door-jamb label for front and rear tire sizes. Many R8s are staggered. If the rear tire size differs, your rear wheel width and offset will likely differ too.
If wheels are off the car, read the inside barrel. Look for size (example 19x8.5J) and offset marking (example ET42). Record front and rear separately.
Keep the baseline above in mind. Treat it as a reference, not a guarantee for every trim.
2) Use the calculator on wheelinterchange.com
Set Installed on to Audi R8, 2014.
To compare an aftermarket fit, use Custom wheel size and Custom tire size. Adjust rim diameter, width, and offset. The tool updates tire diameter as you change rim diameter.
If comparing to a donor vehicle, set Wheels from accordingly. This shows inner clearance and poke changes against your R8 baseline.
If your car is staggered, run the calculator twice. Once with front values, then again with rear values.
3) Confirm bolt pattern, hub, and fasteners
Bolt pattern must match 5x112. A different pattern is not compatible.
Center bore on the R8 is 57.1 mm. A donor wheel with a larger bore needs 57.1 mm hub-centric rings. A smaller bore is not recommended, as machining weakens the wheel.
Thread size is M14 x 1.5. Verify fastener seat type matches the wheel manufacturer’s spec before driving.
4) Check inner and outer clearance in the tool
Offset controls where the wheel sits. Higher ET pulls the wheel inward. Lower ET pushes it outward.
Use the calculator’s inner clearance and poke numbers to anticipate fender and suspension proximity.
Big brake packages need spoke clearance. Visualize with the tool, then test-fit to confirm there is safe space between caliper and spokes.
5) Keep overall tire diameter close to OEM
Large diameter changes can affect ABS, traction control, and speedometer.
Watch the calculator’s tire diameter comparison. Stay as close as practical to the OEM diameter for each axle.
6) Prepare for mounting
Clean the hub face and wheel mounting pad. Remove corrosion.
If using hub-centric rings, seat them fully on the wheel before mounting.
Hand start M14x1.5 bolts and use a guide pin to support the wheel. Tighten in a star pattern. Torque to the specification in your owner’s manual. Re-torque after a short drive.
Validation
With the car on the ground, turn the steering from lock to lock. Listen for contact.
Drive slowly over a speed bump while steering. Check for fender or liner rub.
Perform a short road test. Verify no vibration, no pulling, and normal steering return.
After the test, inspect for witness marks inside the wheel well and near brake lines.
Recheck torque once the wheels have cooled.
Troubleshooting
Vibration at speed
Confirm the wheel is hub-centric to 57.1 mm using proper rings.
Have the wheels road-force balanced. Inspect for bent rims or flat spots.
Verify bolt torque and correct fastener seat type.
Rubbing on fender or liner
Use the calculator to reduce width or adjust offset toward OEM.
Select a tire with a narrower section width or slightly different profile within OEM diameter constraints.
If rubbing is inner, a small spacer can move the wheel outward. Confirm thread engagement and fender clearance before
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.
