2012 Audi R8 Wheel Interchange
2012 Audi R8 Wheel Fitment Guide
If you’re eyeing a wheel swap on your 2012 Audi R8, think of this page as a calm, practical walkthrough. We’ll clear up what matters, show the verified specs we have, and point you to the on-page calculator on wheelinterchange.com for precise comparisons.
1. Misconception
If a wheel is 5x112 from another Audi, it will fit the R8 without issue.
2. Why it seems true
Lots of Audis share a 5x112 bolt pattern and a 57.1 mm center bore. Listings often highlight those two numbers, so it feels like a simple match. The car may even look like it has room at a glance.
3. What is true
The R8’s brakes, offset needs, and spoke clearance can be more demanding than other Audi models. Bolt pattern and center bore are only the starting points. Offset, width, and tire diameter changes drive inner clearance and fender poke. Here’s the verified OEM fitment we have for the 2012 R8 on this page:
| Bolt pattern | 5x112 |
| Center bore | 57.1 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 19 in |
| Rim width | 8.5 in |
| Wheel offset (ET) | 42 mm |
| Backspacing | 5.9 in |
| Tire size | 235/35R19 |
This is one documented OEM configuration for the 2012 R8. Some trims use staggered setups with different rear sizes. If your car differs, use the on-page calculator and your owner’s documentation to confirm your exact factory setup before comparing.
Helpful mental model:
- Offset shifts the wheel inboard or outboard. Higher ET tucks the wheel in; lower ET pushes it out.
- Width changes split roughly half inward and half outward from the hub face.
- Backspacing ties offset and width together, showing how close the inner barrel sits to suspension and brakes.
- Keeping overall tire diameter close to stock helps speedometer accuracy and clearance.
4. Implications
What this means in practice is straightforward with a few rules of thumb and checks:
- Brake and spoke clearance: The R8’s calipers are large. Even with correct bolt pattern, a wheel’s spoke shape and pad height need enough room. Ask the wheel maker for a brake template or pad height spec and compare against your measured caliper protrusion.
- Hub-centric fit: The R8 hub is 57.1 mm. If your wheel’s center bore is larger, plan for hub-centric rings sized to 57.1 mm to keep vibration in check.
- Hardware: Thread size is M14 x 1.5. Match seat type to the wheel design and confirm proper thread engagement length. When in doubt, check the wheel manufacturer’s guidance.
- Tire diameter and gearing feel: Bigger diameters can reduce fender and liner clearance and can change acceleration feel. The calculator will show diameter deltas so you can judge impact.
- Staggered possibility: Many R8 setups are staggered. If your rear wheels or tires differ from front, compare front-to-front and rear-to-rear separately in the calculator.
- Load and speed ratings: Use tires that meet or exceed the OEM ratings for safety and performance margins.
5. Quick tests
- Caliper clearance mock-up: Hold a straightedge across the hub face and measure to the furthest caliper point. Compare that number to the wheel’s pad height and spoke drop from the manufacturer.
- Inner clearance sanity check: In the calculator, try a small offset change and watch “inner clearance” vs “poke” change. If inner clearance shrinks too much, consider a slightly lower width or offset adjustment.
- Diameter check: Use the calculator to keep total tire diameter close to the OEM value shown. Even a small change will display as a percentage for easy comparison.
- Mounting feel: With hub-centric rings (if needed), the wheel should center smoothly on the hub. Any wobble during hand tightening hints at a centering issue.
- Steering and compression test: After installation, turn lock-to-lock at low speed on level ground and drive over a gentle bump. Listen and feel for rubbing under load.
Using the wheelinterchange.com calculator effectively
Think of the calculator as a before-and-after overlay of your setup. Quick recap of how to use it for a 2012 R8:
- Set “Installed on (your vehicle)” to 2012 Audi R8.
- For “Wheels from (donor vehicle),” choose the car you’re borrowing specs from, or enter the custom wheel size directly.
- Adjust “Custom wheel size” to test different rim width, diameter, and offset. The tool shows inner clearance and poke changes against your R8’s baseline.
- Adjust “Custom tire size” to see how section width and aspect ratio affect overall diameter. Changing rim diameter will update the tire diameter comparison, so you can keep things balanced.
- If your R8 uses a staggered setup, run the calculator twice: once for front, once for rear, matching each end’s OEM tire and wheel specs.
Tools and helper items
- 1/2 inch torque wrench for even, accurate fastening.
- M14x1.5 lug bolts matched to your wheel’s seat type.
- Wheel hanger guide pin M14x1.5 to line up heavy wheels on the hub.
- 57.1 hub-centric rings if your wheel bore is larger than 57.1 mm.
How to double-check with OEM sources
- Owner’s manual and door-jamb label for tire sizing, load, and speed ratings.
- OEM wheel part numbers and specifications from an Audi dealer or parts catalog.
- Wheel manufacturer data sheets for pad height, spoke profile, and brake template PDFs.
