2010 Audi A5 Wheel Interchange
2010 Audi A5 Wheel Interchange Guide
You want to know which wheels from other vehicles will safely fit your 2010 Audi A5. The problem is clear: dimensions must match under real-world constraints, or you risk rubbing, vibration, or hardware failure. I’ll walk you through the fitment basics, how to use the on-page calculator, and how to validate before you buy or install.
1) Goal
Select and verify interchangeable wheels for a 2010 Audi A5 using the OEM baseline, the wheelinterchange.com calculator, and physical checks. The aim is safe clearance, correct centering, proper hardware engagement, and a tire diameter that stays within a reasonable range of stock.
2) Prerequisites
Known 2010 Audi A5 OEM fitment baseline. Some items can vary by trim or package, so validate with your owner’s manual, the driver’s door jamb label, or a dealer by VIN.
| Bolt pattern | 5x112 |
| Center bore (mm) | 66.6 |
| Thread size | M14 x 1.5 |
| Rim diameter (in) | 17 |
| Rim width (in) | 7.5 |
| Wheel offset (ET, mm) | 28 |
| Backspacing (in) | 4.85 (reported; validate with the calculator or a physical check) |
| Tire size | 225/50R17 |
Assumptions and constraints:
- Seat type of the lug hardware is not provided. Confirm the seat profile on your wheels and hardware.
- Brake package and trim can affect spoke and barrel clearance. Visual inspection is recommended.
- If your car shipped with a different OEM wheel option, use that as the baseline in the calculator.

3) Step by step
Step 1: Set your OEM baseline in the calculator
Open the wheelinterchange.com calculator on this page. Under “Installed on (your vehicle),” set the OEM wheel and tire to the values above. If your door label or manual shows a different OEM size, use that instead. This gives you an accurate baseline for clearance and tire diameter.
Step 2: Enter the donor wheel or a custom size
Under “Wheels from (donor vehicle),” enter the wheel size and offset from the wheels you want to fit. You can also use “Custom wheel size” to try different rim width, diameter, and offset values. Set “Custom tire size” if you plan a different tire. The calculator will update inner clearance, outer poke, and tire diameter change.
Step 3: Check bolt pattern and center bore first
- Bolt pattern must be 5x112. If it is not, the wheel is incompatible.
- Center bore on the Audi hub is 66.6 mm. A wheel with a smaller bore will not seat. A larger bore can work only with hub-centric rings sized to 66.6 mm on the inner side and the wheel’s bore on the outer side.
Step 4: Verify thread size and hardware
- Thread size is M14 x 1.5. Confirm the fasteners match the thread and seat profile of the wheel.
- Many Audis use lug bolts instead of lug nuts. Hardware type and seat shape can vary by wheel. Use hardware that matches the wheel seat, thread, and length requirements.
Step 5: Evaluate offset and width changes
Offset affects where the wheel sits relative to the hub. Lower ET pushes the wheel outward. Higher ET pulls it inward. Width changes split to inner and outer by half the difference. The calculator shows:
- Inner clearance change: impact to strut, spring perch, and inner liner.
- Outer poke change: impact to fender and bumper cover.
Trade-off: pushing wheels outward can clear inner parts but may hit the fender. Pulling them inward can clear the fender but may hit the strut. Use the calculator to balance these constraints.
Step 6: Keep overall tire diameter in a reasonable range
The calculator shows tire diameter and speedometer change. A common recommended target is to keep overall diameter within about ±3% of OEM. This helps protect ABS and stability control assumptions, and keeps gearing and speed readings reasonable. Always maintain equal or higher tire load index than stock.
Step 7: Confirm brake and spoke clearance
Spoke shape can interfere with calipers even when diameter and width look fine. Use a straightedge across the hub face and measure to the nearest caliper point. Compare with the wheel’s backpad-to-spoke clearance. When in doubt, test fit a bare wheel to confirm spoke clearance before mounting tires.
Step 8: Physical measurement for backspacing validation
Backspacing is the distance from the wheel mounting pad to the inner rim lip. The reported value above is 4.85 in. If this seems inconsistent with your wheel markings, measure it:
- Lay a straightedge across the inner rim lip.
- Measure from the mounting pad to the straightedge.
- Compare with the calculator’s computed backspacing for your size and ET.
Step 9: Test fit and clearance check
- Mount one front wheel and one rear wheel.
