2013 Audi A5 Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2013 Audi A5.

Goal

You need to confirm safe wheel and tire fitment for a 2013 Audi A5. This guide explains the checks and adjustments I recommend. Follow steps to avoid rubbing, improper fasteners, or unsafe clearances.

Prerequisites

  • Known OEM fitment for 2013 Audi A5 supplied here: bolt pattern 5x112, center bore 66.6 mm, thread M14 x 1.5, rim 17x7.5, offset ET28, backspacing 4.85 in, tire 225/50R17.
  • Access to the on-page wheel/tire calculator to compare donor wheels and adjust custom sizes. The calculator updates tire diameter when rim diameter changes.
  • Basic tools: torque wrench, jack and stands, caliper or ruler for clearance checks, test drive route.
  • Access to your vehicle's owner manual or dealer resources to validate torque and brake options. Some values vary by trim; do not assume they are identical across models.

Step by step

1. Verify OEM baseline

Record the provided OEM values into the calculator or your notes. Use this as the reference fitment. Do not replace these values with guesses.

2. Compare donor or custom wheel with the calculator

Enter the donor wheel sizes in the on-page calculator to compare track width, overall diameter, and clearance. Adjust custom rim diameter, width, offset, and tire sizes to see the numeric differences. Remember that changing rim diameter updates the tire diameter automatically.

3. Check center bore and fastening

Confirm center bore 66.6 mm matches the wheel. If the wheel bore is larger, plan to use hub-centric rings sized for 66.6 mm. If the bore is smaller, the wheel will not fit. The thread size M14 x 1.5 is the fastener thread specification. Confirm whether your car uses studs or lug bolts and the correct lug type before installation.

4. Measure physical clearances

Measure brake caliper clearance, suspension components, and inner fender clearance. Some Audi A5 trims have larger brakes than others. If brake size is unknown, measure clearance on the car or compare caliper dimensions to the wheel inner barrel before final selection.

5. Consider spacers and adapters carefully

Spacers change effective offset and track width. They can solve minor clearance issues but introduce trade-offs such as added load on studs and altered scrub radius. Use hub-centric spacers that match 66.6 mm bore if possible. Validate stud length and thread engagement when adding spacers.

6. Install, torque, and validate

Mount the wheel, torque fasteners to OEM specified values, and re-torque after 50 to 100 miles. If you do not have the OEM torque value, obtain it from the owner manual or dealer before proceeding. Perform a slow test drive and check for vibration or rubbing.

Validation

Use these validation checks before calling the job complete.

  • On-page calculator: confirm no more than a few percent change in overall tire diameter to avoid large speedometer error.
  • Physical check: spin the wheel and watch for rub at full lock and full suspension compression.
  • Fastener check: confirm thread engagement of at least the stud's threaded length or consult fastener supplier recommendations.
  • Centering: wheel should seat flush on the hub. If there is wobble, use appropriate hub-centric rings sized to 66.6 mm.
  • TPMS and valve clearance: ensure sensor clearance and recommended tire pressure settings are compatible.

Troubleshooting

Problem: Wheel does not clear brake caliper

Solution: Check wheel inner barrel and spoke clearance. Reduce wheel width or choose higher offset to move the wheel outward or inward as needed. Confirm caliper size variation by trim before changing wheels.

Problem: Wheel wobbles or is not centered

Solution: Use hub-centric rings sized for 66.6 mm. Verify hub face is clean and free of corrosion. Re-seat the wheel and tighten in a star pattern.

Problem: Fastener threads do not match

Solution: Confirm thread size M14 x 1.5 on your car. If the wheel requires different threads, replace fasteners with the correct type. Do not force mismatched bolts or studs.

Problem: Excessive steering feedback or vibration after spacers

Solution: Check spacer quality and wheel runout. Consider reducing spacer thickness or using a single-piece hub-centric spacer to minimize trade-offs. Re-balance the wheel and tire assembly.

Wrap up

You now have a clear checklist to confirm fitment for a 2013 Audi A5. Use the on-page calculator to quantify changes and validate clearances physically. When in doubt, confirm torque, brake options, and fastener types with OEM documentation or dealer support. These steps reduce risk and give you confidence to implement the final wheel choice safely.
