2013 Audi A4 Wheel Interchange

2013 Audi A4 Wheel Interchange, Fitment, and Upgrade Guide | wheelinterchange.com

Known OEM Fitment For 2013 Audi A4

The following specifications reflect the known factory fitment data available for the 2013 Audi A4. Trims and option packages can vary. Always confirm against your door-jamb label, owner manual, or an Audi dealer before buying wheels or tires.

If your A4 has a different wheel or tire size shown on the door-jamb label, use that as your baseline and compare it in the on-page calculator.

How To Use The Wheel Interchange Calculator

The calculator on this page lets you compare donor wheels to your 2013 Audi A4 and test custom sizes. Follow these steps:

• Set Installed on to 2013 Audi A4 so your baseline is correct.
• Use Wheels from to pick a donor vehicle if you have a candidate set in mind. If you do not know the donor, leave it blank and use Custom wheel size.
• Adjust Custom wheel size to test different rim diameter, width, and offset. The tool updates inner clearance and outer poke so you can spot rubbing risks.
• Adjust Custom tire size for section width and aspect ratio. When you change rim diameter, the calculator updates overall tire diameter in the comparison.
• Keep overall tire diameter change within about plus or minus 3 percent to limit speedometer, ABS, and traction control impact.
• Watch inner clearance to struts and control arms and outer poke to the fender lip. Aim for a few millimeters of margin for suspension flex and tire growth.

After modeling in the calculator, verify physically. Measure current clearances, check brake caliper shape, and test fit whenever possible.

Fitment Checklist Before You Buy

• Bolt pattern match: Your A4 uses 5x112. Do not force 5x114.3 or use wobble solutions.
• Center bore: The hub is 66.6 mm. A wheel with a larger bore can fit with hub-centric rings. A wheel with a smaller bore will not fit.
• Fasteners: Thread is M14 x 1.5 and the A4 uses wheel bolts. Match bolt seat type to the wheel design and confirm required bolt length, especially with spacers.
• Offset and width: Compare inner and outer positions in the calculator to avoid strut and fender contact. Do not assume a range. Measure your car.
• Brake clearance: Confirm spoke and barrel clearance over your front and rear calipers. Some trim or brake packages differ.
• Tire diameter: Keep overall diameter close to stock to protect speedometer accuracy and driver assist systems.
• Load and speed ratings: Meet or exceed the OEM load index and speed rating shown on your door-jamb tire label.
• TPMS: Sensor type and reset procedure can vary by market or trim. Confirm your car’s system before buying wheels or tires.
• Spacers or adapters: If required, use hub-centric parts and extended wheel bolts. Recheck that the hub lip still centers the wheel.

Plus Sizing And Common Upgrades

The sizes below are commonly explored by A4 owners. They are not a guarantee of fit. Use the calculator and verify clearances on your specific car, especially if lowered or running big brakes.

• Plus 1 to 18 in: Tires such as 235/45R18 or 245/40R18 can keep diameter near stock. Compare inner and outer positions against your chosen wheel width and offset.
• Plus 2 to 19 in: Tires such as 245/35R19 or 255/35R19 are typical targets. These require careful offset selection and brake clearance checks.
• Winter setups: Many owners prefer a 17 in package with a narrower 225 section for snow clearance and ride quality. Confirm load index.

Important: Offset, width, and tire profile must be chosen together. Small offset changes can move the wheel several millimeters and cause rubbing. Always model your exact combination in the calculator, then test fit.

Installation Tips

• Clean and inspect hubs. Remove rust and debris so wheels seat flat. Lightly brush the hub face and the center pilot.
• Dry fit first. Spin the wheel by hand to confirm caliper and strut clearance before mounting a tire or lowering the car.
• Use a wheel hanger guide pin for bolt-on hubs. It centers the wheel and protects threads.
• Hand start all bolts. Tighten in a star pattern in two to three stages.
• Torque to the value in your owner manual and recheck after 50 to 100 miles.
• Hub rings. If your wheel bore is larger than 66.6 mm, install appropriate rings so the wheel is hub-centric.
• Spacers. Only use hub-centric spacers that maintain a center lip. Install extended bolts with proper thread engagement. Recheck clearance and torque.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• Wheel hanger guide pin M14x1.5
• 66.6 mm hub-centric rings
• Digital tire pressure gauge

Before purchasing fasteners or rings, match seat type, lengths, and diameters to your specific wheels. When in doubt, consult the wheel manufacturer or an Audi dealer.

FAQs

What is the bolt pattern for the 2013 Audi A4?
5x112.

What center bore do I need?
66.6 mm at the hub. Wheels with a larger bore can use hub-centric rings. Wheels with a smaller bore will not fit.

What wheel fasteners does the A4 use?
M14 x 1.5 wheel bolts. Seat type and bolt length depend on the wheel and any spacers. Confirm with the wheel supplier.

Will wheels from another make or model fit my A4?
Only if the bolt pattern is 5x112 and the offset, center bore, brake clearance, and tire diameter all work on your car. Use the calculator and test fit. Do not rely on bolt pattern alone.

Can I run 18 or 19 inch wheels?
Often possible, but not guaranteed. Keep overall tire diameter close to stock, check inner and outer clearances in the calculator, and verify brake clearance.

Do I need hub-centric rings?
If your wheel’s center bore is larger than 66.6 mm, yes. Choose rings that match 66.6 mm to your wheel’s bore size and a material suitable for street use.

Can I use spacers?
Yes if needed for clearance, but they reduce effective offset. Use hub-centric spacers and extended bolts with proper thread engagement. Recheck torque after driving.

What is the correct torque for the wheel bolts?
This can vary by trim and market. Refer to your owner manual or an Audi dealer. Always torque in a star pattern and recheck after 50 to 100 miles.

What about TPMS on the 2013 A4?
Sensor type and reset procedures can vary by trim and region. Check your owner manual or consult a dealer before purchasing sensors or wheels.
