2011 Audi A5 Wheel Interchange

2011 Audi A5 wheel fitment, bolt pattern, and swap guide

This page summarizes the known OEM wheel and tire specs for the 2011 Audi A5 and explains how to use the on-page calculator to compare donor wheels and tires before you buy. Values can vary by trim and market. If anything on your car differs from the table, defer to your owner’s manual and the physical markings on your wheels, tires, and hardware.

Known OEM wheel and tire specifications

Notes: Backspacing is sometimes reported differently depending on how rim width is measured. If you are mixing OEM and aftermarket wheels, measure backspacing directly as described below and verify using the calculator.

Approximate OEM tire diameter

With a 225/50R17, the overall tire diameter is about 25.86 inches. This is an estimate that can vary by tire model and tread depth. When exploring size changes, a common rule of thumb is to keep overall diameter within about 3 percent of stock to help maintain speedometer accuracy and ride/handling balance.

How to use the wheel and tire comparison calculator

The calculator on this page compares “Wheels from” a donor vehicle to what will be “Installed on” your 2011 Audi A5. You can also enter a custom wheel and tire size. Follow these steps:

• Select the donor vehicle or enter a custom rim diameter, rim width, and offset for the wheels you’re considering.
• Enter the custom tire size if it differs from the donor. Changing rim diameter updates the compared tire diameter automatically so you can see how overall size changes.
• Review inner clearance (suspension/brakes) and outer poke (fender) changes. Aim to avoid reducing inner clearance to the point of contact and avoid excessive outer poke that could contact the fender or liner.
• Check speedometer change versus stock diameter and keep the percentage change small unless you also plan to recalibrate.

Always confirm physically on the car. The calculator is a planning tool and does not replace test-fitting.

Critical fit checks before you buy or install

Every wheel and tire swap should be verified on the vehicle. Use this checklist:

• Bolt pattern: Must be 5x112. Pattern adapters introduce extra variables; avoid unless you fully understand the implications and hardware requirements.
• Center bore: The Audi A5 hub is 66.6 mm. If your wheel bore is larger, use quality hub-centric rings sized to 66.6 mm at the hub and to your wheel’s bore on the outer side. Do not use a wheel with a bore smaller than the hub unless it is professionally machined.
• Thread size: Hardware must be M14 x 1.5. Seat type (ball vs cone) can vary by wheel. Match the seat type to the wheel exactly and confirm head size/length. If using spacers, ensure longer hardware with proper engagement.
• Brake and suspension clearance: With wheels installed hand-tight, spin the wheel to confirm caliper and knuckle clearance. Inspect at full lock left/right and through suspension travel if possible.
• Fender and liner clearance: Check clearance at the outer edge under compression and steering lock. Consider added clearance needed for snow chains where applicable.
• Tire overall diameter: Keep within a small percentage of stock to minimize ABS, traction control, and gearing effects.
• Load rating: Wheels and tires must meet or exceed the vehicle’s GAWR/axle loads. Check the markings on the wheel and tire.

Measuring offset and backspacing

Offset (ET) is the distance from the wheel centerline to the mounting pad, expressed in millimeters. Positive ET moves the wheel inward; lower ET moves it outward. Backspacing is the distance from the mounting pad to the inner wheel lip, in inches. Because rim width can be specified as measured bead-to-bead and lips add extra width, calculated backspacing and measured backspacing can differ. If you are comparing a wheel to the value listed above, measure with a straightedge across the inboard rim and a ruler to the mounting pad, and verify with the calculator.

Hardware, torque, and TPMS

Hardware: The thread size is M14 x 1.5. Verify whether your vehicle uses wheel bolts or studs/nuts and match seat type and length to the wheel and any spacer used. If spacers are added, hardware must be longer to maintain safe thread engagement and the setup should remain hub-centric.

Torque: Wheel fastener torque can vary by trim and hardware. Refer to the owner’s manual or OEM service information and use a torque wrench to tighten in a star pattern on clean, dry threads unless otherwise specified by the manufacturer. Recheck torque after 50–100 miles of driving.

TPMS: Sensor type and relearn procedures vary by market and equipment. If your vehicle uses direct sensors, either transfer your sensors to the new wheels or install compatible sensors and perform the relearn per OEM instructions.

If you need to deviate from stock sizing

Use the calculator to simulate changes in rim width and offset and watch how inner clearance and outer poke change. Small increases in width combined with thoughtful offset adjustments can maintain inner clearance while avoiding excessive poke. Always verify brake caliper clearance and consider that tire section width varies by brand and by the exact wheel width used.

Useful tools and parts

• 1/2 inch torque wrench
• 17 mm thin-wall wheel socket
• M14 x 1.5 wheel bolts (confirm seat type and length for your wheels)
• 66.6 mm hub-centric rings (match the outer size to your wheel bore)

Final safety notes

Do not rely on a single spec when swapping wheels. Confirm bolt pattern, center bore, offset, brake clearance, tire diameter, and hardware details as a complete system. If any dimension is unknown for your specific trim, use the on-page calculator with your measured values and cross-check against your owner’s manual and OEM service sources before driving.
