2014 Audi A5 Wheel Interchange

2014 Audi A5 wheel fitment guide

This page tackles the common problem first. You want different wheels or need to cross-fit from another vehicle, but you are not sure what actually fits your 2014 Audi A5 without rubbing, vibration, or hardware issues. I will walk you through a safe, technician-grade process using the on-page calculator and verified baseline specs.

1. Goal

Make confident wheel and tire choices for a 2014 Audi A5, within real-world constraints. Use the calculator to compare donor wheels, validate clearance, and keep ride quality and safety intact.

2. Prerequisites

• Know your baseline. Check the driver door placard and owner’s manual, then compare to the specs table below.
• Use the WheelInterchange calculator on this page to compare donor setups against your A5.
• Have basic tools for measuring and install.

• 1/2 inch torque wrench: Amazon search
• Digital caliper for hub and bolt checks: Amazon search
• Hub-centric rings sized to your wheel bore and 66.6 mm hub: Amazon search
• M14x1.5 wheel bolts, verify seat type before purchase: Amazon search

3. Step by step

3.1 Confirm your baseline fitment

These values are documented for the 2014 Audi A5. Some values can vary by trim or package. If something differs on your door placard, treat that as your baseline and use the calculator to validate.

Note the mixed entries for wheel and tire. That indicates multiple factory configurations. Verify your actual stock wheel and tire sizes on the car, then proceed with comparisons.

3.2 Use the calculator to compare donor wheels

• Set Installed on to 2014 Audi A5.
• Set Wheels from to the donor vehicle you are considering.
• If you have exact hardware, use Custom wheel size and Custom tire size to enter rim diameter, width, offset, and tire section width and aspect ratio.
• Assumption: a larger rim with a lower-profile tire can keep overall diameter close. The calculator updates tire diameter when you change rim diameter, so you can manage rolling diameter and speedometer impact.

3.3 Read the clearance changes

Watch these outputs in the comparison.

• Inner clearance: decreases when backspacing increases or offset increases with the same width. Risk is contact with strut, spring, or liner.
• Outer poke: increases when offset is lower or width is higher. Risk is fender rub.
• Overall tire diameter: keep within a modest variance from your baseline. A commonly recommended target is within about 2 to 3 percent, but confirm drivability and local inspection rules.

3.4 Validate hub and brake fit

• Center bore: your hub is 66.6 mm. A wheel with a larger bore can be made hub-centric using rings sized to 66.6 mm. A wheel with a smaller bore will not fit.
• Brake caliper clearance: use a template if available, or test-fit with the wheel torqued. Spin the wheel and listen for contact.

3.5 Fastener checks

• Thread size is M14x1.5. Do not force mismatched threads.
• Bolt or nut seat style must match the wheel seat, for example ball or cone. Seat type can vary by wheel, so confirm before purchase.
• If spacers are used, longer bolts may be required. Only use hub-centric spacers that match 66.6 mm hub and ensure proper bolt engagement. This is a trade-off and adds another variable to validate.
• Torque to the OEM spec listed in your owner’s manual, then re-torque after short mileage.

3.6 Tire selection

• Enter the tire’s section width and aspect ratio in the calculator to see diameter and clearance changes.
• Check load index and speed rating meet or exceed OEM requirements for your trim.

4. Validation

• With the car on the ground, turn lock-to-lock and check inner fender liners and control arm clearance.
• Drive over a speed bump at low speed and listen for contact at the rear arch and front fender lip.
• Highway test at 55 to 70 mph. If there is vibration, stop and diagnose before continued use.
• Re-torque fasteners after 50 to 100 miles, in a star pattern, to the OEM torque spec.
• After a week, inspect for witness marks inside the wheel barrel and on plastic liners.

5. Troubleshooting

• Vibration above 55 mph: likely non-hub-centric fit, improper torque, or balance. Use 66.6 mm hub rings if the wheel bore is larger. Re-balance and verify no bent wheel.
• Rubbing at full lock: offset may be too low or width too high. In the calculator, reduce width or increase offset and observe inner and outer changes to find a safer combination.
• Rubbing on bumps: overall tire diameter or outer poke is excessive. Choose a tire with a slightly lower aspect ratio or a wheel with a slightly higher offset, then re-validate.
• Bolts bottoming out or not engaging enough threads: confirm M14x1.5, correct length, and correct seat type for the wheel. Never mix seat styles.
• TPMS warning: system type can vary by market and trim. Some vehicles use sensors in the wheel, others use indirect ABS-based monitoring. Check the owner’s manual and carry over or program sensors as required.
• Speedometer error: if the calculator shows a notable diameter change, select a tire size that brings the percentage difference closer to baseline.

6. Wrap up

You now have a clear path from uncertainty to a validated setup. Start with your 2014 Audi A5 baseline, use the calculator for donor comparisons, and pay close attention to offset, width, and diameter trade-offs. When a spec is unknown or varies by trim, confirm it on your door placard, owner’s manual, and through the calculator. This approach keeps your fitment safe, hub-centric, and free of rubbing.

For more options, repeat the comparison with different donor vehicles and custom sizes until the calculator shows acceptable inner clearance, outer poke, and tire diameter. Then validate physically before committing to tires.
