2011 Audi S4 Wheel Interchange

2011 Audi S4 Wheel Interchange, Specs, and Fitment Guide

Known OEM Fitment For 2011 Audi S4

The following factory specifications are confirmed for the 2011 Audi S4. If your vehicle has a special package or non-stock wheels, verify on your car and with OEM sources before ordering.

Notes:

• Wheel bolt seat style can vary by wheel. Verify whether your wheel bolts use ball seat or cone seat and only use the matching seats with your wheels.
• If your car is not on its original suspension or brakes, clearances can change. Always measure on the vehicle.

How To Use The Wheel Interchange Calculator

Use the calculator on this page to compare a potential donor wheel and tire to your 2011 Audi S4. It shows inner and outer clearance changes, ride height differences, and speedometer impact.

• Choose Wheels from to represent the donor wheel and tire. This could be another Audi or a custom size you want to try.
• Choose Installed on to represent your 2011 Audi S4. The OEM values above are a good starting point.
• To try aftermarket setups, open Custom wheel size and enter rim diameter, rim width, and offset. Then set Custom tire size for section width and aspect ratio.
• As you change rim diameter, the tool updates the compared tire diameter so you can see total height change.
• Focus on clearance deltas: inner clearance to the strut or control arm, and outer poke relative to the fender. Aim to avoid inner contact and outer rubbing under compression and steering.

Confirm fitment by combining the calculator results with physical measurements on your car and by checking OEM documentation or a dealer. If any spec on your vehicle differs from the table above, update the calculator inputs to match what you have.

Fitment Checklist Before You Buy

• Bolt pattern: Wheel must be 5x112.
• Center bore: Hub bore on the car is 66.6 mm. If the wheel bore is larger, plan for hub-centric rings sized to 66.6 mm inner diameter. If the wheel bore is smaller, the wheel will not seat.
• Offset and width: Use the calculator to confirm inner clearance to suspension and outer fender coverage. Check at full steering lock and with suspension compressed.
• Brake caliper clearance: Test spoke and barrel clearance over your front and rear calipers. Paper or clay gauge checks are helpful.
• Tire diameter: Keep overall tire diameter close to stock to protect ABS, speedometer accuracy, and gearing. The calculator shows the percentage difference.
• Load rating: Wheel and tire load indexes must meet or exceed the vehicle requirements listed in your owner manual or door jamb placard.
• TPMS: Verify sensor compatibility and frequency for your market. Relearn may be required after installation.
• Wheel fasteners: Thread size is M14 x 1.5. Verify bolt length and seat type match the wheels. Never mix seat types.
• Spacers: If spacers are used, ensure hub-centric design, proper center bore, and appropriate longer bolts to achieve OEM-specified thread engagement.

Plus Sizing And Common Upgrades

Plus sizing changes rim diameter and tire dimensions to maintain similar overall tire height while altering handling and appearance. The correct fit will depend on your exact wheel width, offset, suspension, brake package, and fender clearance. Use the calculator to validate every change and measure on your vehicle before purchase.

Example tire diameter strategies you can test in the calculator:

• Plus 1 from 18 inch: Many owners explore 19 inch options with tire sizes that keep overall diameter near stock, such as 245/35R19 or 255/35R19. Verify width and offset for clearance.
• Minus sizing for winter: Some choose a narrower section width to improve snow traction, keeping overall diameter close to stock. Confirm brake clearance with any smaller wheel diameter.

These are example sizes to evaluate, not guaranteed fitments. Always confirm offset, width, brake clearance, and fender room on your specific 2011 Audi S4 using the calculator and physical checks.

Installation Tips

• Preparation: Park on level ground, use wheel chocks, and support the car with properly rated jack stands. Do not work under a car supported only by a jack.
• Hub cleaning: Clean the hub face and center pilot with a wire brush. A very light film of anti-seize on the hub pilot can help prevent future sticking. Do not apply lubricants to wheel bolt threads or seats unless the OEM procedure specifies it.
• Test fit dry: Mount one front and one rear without tires when possible to check caliper and spoke clearance. Spin by hand to ensure no contact.
• Fasteners: Verify seat type and length. Hand start bolts to avoid cross-threading. Tighten in a star pattern.
• Torque: Use the torque specification in the Audi service manual for M14 x 1.5 wheel bolts on this vehicle. Re-torque after 50 to 100 miles of driving.
• TPMS: Install compatible sensors and perform relearn if required. Check for leaks at the valve seats.

FAQs

What is the bolt pattern on the 2011 Audi S4?
5x112. The wheel must have 5 lugs on a 112 mm circle.

What is the center bore on the 2011 Audi S4?
66.6 mm. If the wheel bore is larger, use hub-centric rings with a 66.6 mm inner diameter to keep the wheel centered.

What is the OEM tire size and wheel size?
The provided OEM setup is 18x8.0 ET47 with 245/40R18 tires. If your car shows something different, enter your actual values in the calculator and verify against OEM documentation.

Will 19 inch wheels fit?
Many owners evaluate 19 inch packages. Fitment depends on wheel width, offset, and brake clearance. Use the calculator to keep total tire diameter close to stock and measure inner and outer clearances on the car.

Do I need hub-centric rings?
If your new wheel has a center bore larger than 66.6 mm, yes. Order rings sized for your wheel’s outer bore to 66.6 mm inner bore. If the wheel bore is 66.6 mm, rings are not required.

Can I use spacers on the 2011 S4?
Spacers reduce offset and push the wheel outward. Only use hub-centric spacers that match 66.6 mm hub bore and ensure you have appropriately longer M14 x 1.5 bolts with OEM-specified thread engagement. Recheck fender clearance.

What torque should I use on the wheel bolts?
Follow the Audi service manual torque for M14 x 1.5 wheel bolts for your S4. If you do not have the manual, contact a dealer for the exact value. Re-torque after initial miles.

Are my OEM bolts ball seat or cone seat?
Seat style can vary by wheel. Inspect the bolt seats on your current wheels and match them exactly on any new wheel. Never mix bolt seat types.

Will staggered setups work?
Staggered width can be evaluated with the calculator, but confirm that tire rolling diameters remain close front to rear and that stability control and AWD systems are not adversely affected. When in doubt, keep square sizing.

How accurate is the calculator?
The calculator models geometry changes for diameter, width, and offset. Final confirmation still requires physical measurement on your vehicle, test fitting over brakes, and verification against OEM sources.
