Audi RS 6 Avant & RS 7 C8 (2021-2026) Wheel Fitment Guide

Q: What wheels come stock on the Audi RS 6 Avant and RS 7 C8?

Every US car came standard on 21x10.5 ET19 wheels with 275/35R21 summer tires. Optional 22s, including the lighter performance-model wheel from 2024, are 22x10.5 ET19 on 285/30R22. All factory summer wheels are square at ET19, so the RS 6 and RS 7 share the same figures throughout this guide.

Q: What are the RS 6 and RS 7's bolt pattern, center bore and lug specs?

Both use a 5x112 pattern, a 66.5mm bore and M14x1.5 ball-seat lug bolts, torqued to 120 Nm (89 lb-ft) per Audi's owner's manual. FMB machines RS 6 and RS 7 wheels for 60-degree conical-seat bolts by default, so a new set runs conical bolts of the correct length. If you want to keep your factory ball-seat bolts, tell us when you order; otherwise the wheels are machined for conical.

Q: What size wheels fit an RS 6 or RS 7 at stock ride height?

Documented at factory height: 22x10.5 ET10 on 285/30R22, 22x11 ET16/ET12 on 315/30R22, 22x11.5 ET25 on 285/30R22, and 21x10.5 ET8–ET14 on 295/35R21. Many 22x10.5 builds at ET7–ET11 run the air suspension's lowering module, and builds at ET5 and below are mostly lowered.

Q: What winter wheels fit the RS 6 and RS 7?

Audi's winter fitment is 21x8.5 ET19 on 245/40R21. Owners commonly run 21x10.5 at ET5–ET8 on 285/35R21 or 295/35R21 winter tires instead, including over carbon-ceramic brakes. No 20-inch winter set is documented without removing the front brake dust shields, so 21 inches is the practical minimum.

The Audi RS 6 Avant and RS 7 C8 share a 5×112 bolt pattern, a 66.5mm center bore, M14×1.5 ball-seat lug bolts and square factory wheels at ET19 in 21 or 22 inches. This guide covers US-market 2021–2026 cars, including performance models: factory wheels, documented 21- to 23-inch builds, and how far each setup sits outside stock.

About this guide: Fitment data is compiled from owner builds on Audizine and owner-submitted build galleries, plus customer cars in wheel-maker fitment galleries, cross-checked against vendor fitment documentation. Use it as research for your build; ride height, tires, and alignment are still your installer's call.

Factory Wheel & Tire Configurations

The RS 6 Avant and RS 7 share the hub hardware below, their wide fenders and every factory wheel size, so one guide covers both. Every factory summer wheel is square at 10.5J ET19: 21-inch on 275/35R21 as standard, 22-inch on 285/30R22 as an option. Those wheels are the reference for every "mm out" figure below.

Audi's narrower 21-inch winter fitment for the C8 RS 6 and RS 7, listed by sellers as 4K0601025AA, 21×8.5 ET19 on 245/40R21. At the same offset but two inches narrower, its outer lip sits about 25mm inside the standard 21. Many owners run a 21×10.5 aftermarket set on winter tires instead.

Aftermarket Options

Aftermarket Wheel & Tire Configurations

Each card below is one aftermarket wheel size and each row on its ladder is one documented build at its effective offset. The Front and Rear figures show how far that build's outer lip sits outside the factory 10.5J ET19 wheel: the 21-inch for 21s, the 22-inch for 22s and 23s. Every factory wheel is square, and so is every carded build.

⚠️ Platform-specific fitment notes — Audi RS 6 Avant & RS 7 C8

Tire size and the front wheel well.

An owner who test-fitted a 295/35R22 found it rubbed the top of the front spindle arm and sat 1–2mm from the fender liner, so documented 22-inch builds stay on 285/30R22 to 315/30R22. Builds at ET0 and below are lowered with camber correction, and the most aggressive one also has rolled front arches.

Brakes and wheel diameter.

Owners know of no 20-inch wheel that fits without removing the front brake dust shields, and one 21×11 build needed smaller Audi shields. Deep-concave faces are documented over both steel and carbon-ceramic brakes, but spoke shape at the caliper varies, so tell us your brake package when you order.

Lug bolts.

The factory bolts are M14×1.5 with a ball (radius) seat. FMB machines RS 6 and RS 7 wheels for 60° conical-seat bolts by default, so a new set runs conical bolts of the correct length. If you want to keep your factory ball-seat bolts, tell us when you order; otherwise the wheels are machined for conical.

Square Setup

What happens when you build with FMB

Built to the exact spec, not the closest one on a shelf. The setups above come from real RS 6 Avant and RS 7 builds, and we CNC-machine every wheel to them directly. If a build needs a spacer to reach its offset, we machine that offset into the wheel instead.

Choose your setup.
This guide is built to give you what you need to pick a spec with confidence: documented RS 6 and RS 7 builds, tire sizes, and how each one fits. If you still have questions, we're happy to help before you order.
Engineering verification.
Our manufacturing partner confirms wheel specs, including bolt pattern, center bore, brake caliper clearance, backspacing and load rating.
Render approval.
You approve the design and final specs before we move forward with production.

Our fitment guarantee

Every set is guaranteed to mount on your RS 6 Avant or RS 7: 5×112 bolt pattern, bored to the 66.5mm hub, machined for 60° conical lug bolts (or your factory ball-seat bolts if you request it when ordering), and made to the exact width and offset you approved.

How a setup sits on your car also depends on ride height, tires and alignment, so choose with your plans in mind.

Common Questions

FAQ — Frequently Asked Questions

What wheels come stock on the Audi RS 6 Avant and RS 7 C8?

Every US car came standard on 21×10.5 ET19 wheels with 275/35R21 summer tires. Optional 22s, including the lighter performance-model wheel from 2024, are 22×10.5 ET19 on 285/30R22. All factory summer wheels are square at ET19, so the RS 6 and RS 7 share the same figures throughout this guide.

What are the RS 6 and RS 7's bolt pattern, center bore and lug specs?

Both use a 5×112 pattern, a 66.5mm bore and M14×1.5 ball-seat lug bolts, torqued to 120 Nm (89 lb-ft) per Audi's owner's manual. FMB machines RS 6 and RS 7 wheels for 60° conical-seat bolts by default, so a new set runs conical bolts of the correct length. If you want to keep your factory ball-seat bolts, tell us when you order; otherwise the wheels are machined for conical.

What size wheels fit an RS 6 or RS 7 at stock ride height?

Documented at factory height: 22×10.5 ET10 on 285/30R22, 22×11 ET16/ET12 on 315/30R22, 22×11.5 ET25 on 285/30R22, and 21×10.5 ET8–ET14 on 295/35R21. Many 22×10.5 builds at ET7–ET11 run the air suspension's lowering module, and builds at ET5 and below are mostly lowered.

What's the difference between flush and aggressive, and how do I read the ladder?

Each card is one wheel size and each row is one documented build at its effective offset. The Front and Rear figures show how far the outer lip sits outside the factory 10.5J ET19 wheel. Most builds sit 8–14mm out; a 22×10.5 at ET-2 front and ET-4 rear sits 21–23mm out, the aggressive end.

Do aftermarket wheels clear the RS 6 and RS 7 brakes?

The steel brakes use 10-piston front calipers, and carbon-ceramics with 440mm front rotors are optional. Owners know of no 20-inch wheel that fits without removing the front dust shields. 21- and 22-inch builds clear both packages, including deep-concave faces, but spoke shape varies. Tell us your brake package before production.

Should I run a square or staggered setup on the RS 6 or RS 7?

Audi fits square wheels on every C8 RS 6 and RS 7, and we found only one staggered build, too few to list. Square sets let you rotate tires and keep quattro on one rolling diameter. Owners who want more presence usually run 22×10.5 or 22×11 on all four corners instead.

Does tire size matter for the RS 6 and RS 7's quattro drive?

Yes. Keep front and rear tires at the same rolling diameter, and replace them as a set where possible. Staggered configurations can produce front-to-rear rolling diameter mismatches that may stress the quattro system over time. The math should be checked against your owner manual before committing — we document tire dimensions on every card; verifying compatibility is your responsibility.

Can I use wheel spacers on an RS 6 or RS 7?

Many owners run 5–17.5mm spacers on the factory 22s or on high-offset aftermarket wheels. Any spacer needs hub-centric rings and lug bolts longer by its thickness. Spacer builds appear here at their effective offset, and FMB machines that offset into the wheel, so a new set needs no spacer.

What winter wheels fit the RS 6 and RS 7?

Audi's winter fitment is 21×8.5 ET19 on 245/40R21. Owners commonly run 21×10.5 at ET5–ET8 on 285/35R21 or 295/35R21 winter tires instead, including over carbon-ceramic brakes. No 20-inch winter set is documented without removing the front brake dust shields, so 21 inches is the practical minimum.

Which RS 6 and RS 7 model years does this guide cover?

US-market C8 RS 6 Avant and RS 7 from 2021 through 2026, including the performance models added for 2024 and the limited 2025 RS 6 Avant GT. Every year shares the hub, brakes and ET19 wheel offset. The C7 RS 7 sold through 2018 is a different car on different offsets and isn't covered here.

Can I swap wheels between the RS 6 Avant, RS 7, A7 and S7?

RS 6 and RS 7 wheels interchange directly: same fenders, 10.5J ET19 sizes and hardware. A7 and S7 wheels bolt on but are narrower at much higher offsets, so they sit well inside the RS fenders. An A7-family wheel at ET35 sits far further in than the factory RS wheel at ET19.
