The B9 A4 sits on one of the most mod-friendly platforms Audi's built. With 5x112mm bolt pattern compatibility across the entire VAG lineup, you've got endless wheel options — from OEM+ Audi Sport wheels to aggressive three-piece builds. The stock 17x7.5 +38 setup leaves plenty of room to go wider and lower without major fender work.

Most B9 owners start conservative with 19x8.5 +35 square setups for that subtle OEM+ look. But this platform can handle way more aggressive fitment. We've put together 12 different wheel setups that show exactly what fits — from tucked track builds running -3° camber to daily-friendly flush setups on 20x10s. The B9's got decent fender clearance from the factory, so you can push offset limits without rolling if you dial in the ride height correctly.

Want new wheels for your Audi A4?

The B9 A4 rides on that sweet 5x112 bolt pattern, opening up the entire VAG catalog plus tons of aftermarket options. Stock 17x7.5 +38s are fine for commuting, but they're leaving serious style points on the table. Most owners jump straight to 19s or 20s — the B9's wheel wells can handle the diameter without looking overdone.

The A4 community splits into two camps: the subtle OEM+ crowd running Audi Rotor or Y-spoke designs from the S4/S5, and the aggressive stance guys pushing VMR V710s or TSW Bathursts in 19x8.5 +35. Both approaches work because the B9's clean lines complement everything from classic mesh to modern split-spokes. Just remember you've got about 25mm of strut clearance to work with up front.

Basic A4 fitment info

• Bolt pattern: 5x112mm
• Bolt thread: M14 x 1.5
• Center bore: 66.5mm
• Bolt torque: 89 ft lbs

The stock A4 rolls on 17x7.5 +38 wheels wrapped in 225/50R17 tires.

Brake clearance

The B9 A4 runs different brake setups depending on trim. Base Premium models get 338mm fronts with single-piston floating calipers — these clear most 18" wheels without drama. S line Sport Package cars step up to 354mm rotors with larger calipers that demand careful wheel selection. The real fitment killer? S4 models pack 354mm six-piston fronts that won't clear anything under 19" diameter.

Running aggressive offsets like +25 or lower? You'll need 5-10mm spacers to push past those S line calipers. Even some +35 wheels rub the caliper face depending on spoke design. Pro tip: Rohana RFX series wheels have excellent brake clearance thanks to their stepped spoke profile.

Conservative OEM+ Fitments

These builds keep it clean with minimal suspension work — think 1" drop on coilovers or springs, wheels sitting just inside the fenders with proper tire sizing. Perfect daily setups that won't scrape on driveways or require rolled fenders, running proven sizes like 19x8.5 +35 with 235/35 or 18x9 +42 with 245/40.

Final Thoughts on Audi A4 Fitment

The B9 A4 platform proves incredibly versatile for wheel fitment, with 19x8.5 to 19x9.5 in the +35 to +45 offset range delivering that perfect flush look without major modifications. These Audis handle aggressive setups surprisingly well — you can push 20x10 with proper offset and still maintain daily drivability. The 5x112 bolt pattern opens up endless options from OEM+ refinement to full show car builds.

For those shopping right now, I'd start with 19x9 +40 as your baseline fitment. It's aggressive enough to transform the stance but conservative enough to avoid rubbing issues with stock suspension. Want more poke? Drop to +35 or go 9.5" wide. Planning to lower it on coils? Factor in 5-10mm more positive offset to maintain clearance. The beauty of this platform is how well it responds to thoughtful wheel choices — even subtle changes make a huge visual impact.
