Audi RS5 B9 (2018-2025) Wheel Fitment Guide
The Audi RS5 B9 uses a 5×112 bolt pattern, a 66.5mm center bore and M14×1.5 ball-seat lug bolts, with square factory wheels at ET24 on the 19-inch and ET22 or ET26 on the 20-inch. This guide covers US-market 2018–2025 RS5 Coupe and Sportback models: factory wheels, documented 19- and 20-inch builds, fender clearance, and how far each setup sits outside stock.
About this guide: Fitment data is compiled from RS5 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.

Audi of America lists this 20-inch wheel as forged, in bi-color anthracite (8W0601025DT) or silver (8W0601025DR). Both are 20×9 ET22, the same position as the Competition wheel, which makes it the reference for the 20-inch cards below. Owners on 2021-and-later Sportbacks report ET22 on their factory 20s.

That is why 2018–2019 owners often add 12–15mm spacers to their factory 20s, and why every figure below reads 4mm higher for them.

The milled forged 20-inch option on early cars, listed as 8W0601025CS, 20×9 ET26. Owners describe it as the lightest of the factory 20s. Like the trapezoid wheel it sits at ET26, so a 2019 Sportback on these wheels with 10mm spacers lands at an effective ET16, a documented build in the 20×9 card below.
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 wheel: 9J ET24 for 19-inch cards, 9J ET22 for 20-inch cards. Every factory RS5 wheel is square, and so is every documented build.
Tap a setup to jump to its full card. Fit: Bolt-on = documented at stock ride height with no fender work reported · Lowered = documented on lowering springs or coilovers · Not reported = owners didn't say. Sources = owner builds (including customer cars in vendor galleries) and vendor fitment-guide setups documented on that card.
On 20×10.5 wheels with 285 or 295 tires, owners report contact with the screws or clips at the top-center of the front fender liners, and remove them to run rub-free. A vendor flags the same screws for 285s on 10-inch wheels. Cars on 20×10 at about ET20 with 275s or 285s report no rubbing at stock height.
Brakes and spoke profile.
The RS5 has 375mm six-piston front brakes, with 400mm carbon-ceramics optional, and Audi's smallest factory wheel is 19 inches. Very deep front spoke profiles can sit close to the calipers: one owner measured under a millimeter on a 5mm spacer. Tell us your brakes when you order so caliper clearance is checked.
Lug bolts.
The factory bolts are M14×1.5 with a ball (radius) seat. FMB machines RS5 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.

The RS5's most-documented size and the one vendors point owners to first. ET20 on 275/30R20 or 285/30R20 is the near-flush spec at stock height; ET25–ET26 sits a few millimeters further in for a more conservative look. Go lower than ET20 only on a lowered car, and plan for 285s if you want a square sidewall on a 10-inch rim.

The factory 20-inch width, so the factory 275/30R20 tire carries over. Owners use it to move the face out without a wider tire: from about stock position at ET25 to roughly 8–11mm out on factory wheels with 12–15mm spacers. The vendor-suggested ET10 is the outer limit at stock height on the factory tire.

Half an inch narrower than the factory 19, used by one owner as a winter set. At ET20 the face sits about 2mm inside the factory 19-inch wheel, so it looks like stock while giving a narrower winter tire more sidewall. Check caliper clearance by design, since 19 inches is the smallest factory wheel.

A 19-inch setup for owners who want more sidewall than the 20s without giving up width. It runs 265/35R19 or 275/35R19 and sits 5–13mm outside the factory 19. Both owner builds reach their offset with 5–8mm spacers on ET23–ET25 wheels; a vendor test fit at ET25 is listed as possibly needing modifications.

A half-inch-wider 20 that keeps the factory 275/30R20 tire in its recommended rim range. The one documented build, a 2022 Sportback at ET18, sits about 10mm outside the current factory 20. It's the middle ground owners weigh against a 10-inch rim, which suits a 285 better.

The widest 20 documented on the RS5, usually on 285/30R20 with a deeper-profile rear for the look. ET25 is the common spec and sits about 16mm out. Owners on 285s and 295s report removing the top front fender-liner screws or clips, and most of these cars are lowered; start at ET25–ET27 unless you plan to drop the car.

The track-leaning 19: an inch wider than the factory wheel for a 275/35R19 or 285/35R19 tire with more sidewall than the 20s. One owner runs ET25 on 285s and calls it dead flush; a vendor lists ET20 on 275s without modifications and warns 285s may need the front fender screw removed.

Was this guide helpful?
Let us know how we did on Google.
Your feedback helps other owners find these free fitment guides. It takes about 30 seconds.
Built to the exact spec, not the closest one on a shelf. The setups above come from real RS5 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 RS5 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 RS5: 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.
Every B9 RS5 runs square wheels. The standard wheel is a forged 19×9 ET24 10-spoke-star on 265/35R19. Optional 20×9 wheels on 275/30R20 came at ET26 on 2018–2019 designs and ET22 on the 5-arm-flag, 5-segment-spoke and Competition 5-Y-spoke wheels from 2019 onward. Check the stamp on a spoke if you're unsure which you have.
What are the RS5's bolt pattern, center bore and lug specs?
The RS5 uses 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 A5-family owner's manual. FMB machines RS5 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 RS5 at stock ride height?
Owners most often run 20×10 at ET20–ET26 on 275/30R20 or 285/30R20, and several stock-height cars at ET20 report a near-flush fit with no rubbing. 20×9 keeps the factory 275s, and 19×9.5 or 19×10 on 275/35R19 suits owners who want more sidewall. 20×10.5 works too, but most documented cars are lowered or removed fender-liner screws.
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 wheel: 9J ET24 for 19s and 9J ET22 for 20s. Most RS5 builds sit within 18mm of stock; a lowered 20×10.5 build on spacers sits 31mm out, the aggressive end.
Do aftermarket wheels clear the RS5's brakes?
The RS5 has 375mm six-piston front brakes, with 400mm carbon-ceramics optional, and Audi's smallest factory wheel is 19 inches. Documented 19- and 20-inch builds clear both systems, including a 20×10 ET20 on factory carbon-ceramics. Very deep front spoke profiles can sit within a millimeter of the calipers, so tell us your brakes before production.
Should I run a square or staggered setup on the RS5?
Audi fits square wheels on every RS5, and every build documented here is square, so no staggered card is listed. Square sets let you rotate tires and keep the quattro system on one rolling diameter. Owners who want a staggered look usually run the same size all round with a deeper spoke profile on the rear wheels.
Does tire size matter for the RS5'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 RS5?
Many RS5 owners run 10–15mm spacers on factory 20s to close the gap, especially on 2018–2019 ET26 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 RS5?
Owners commonly fit winter tires on the factory 19×9 ET24 wheels in 265/35R19. Audi's own 19-inch winter set is reported by an owner as 8J ET26, and Audi sells the 20-inch 5-segment-spoke wheel as a complete winter wheel. A 19×8.5 ET20 winter set is documented, sitting about 2mm inside the factory 19.
Which RS5 model years does this guide cover?
US-market B9 RS5 Coupes for 2018–2019 and 2021–2024, and RS5 Sportbacks for 2019 and 2021–2025. Audi skipped the 2020 model year in the US, the 2021 facelift kept the same hub and wheel sizes, and the Coupe ended after 2024. The plug-in hybrid RS5 revealed in 2026 is a new generation and isn't covered here.
Can I put S5 wheels on an RS5, or RS5 wheels on an S5?
They bolt on, with the same 5×112 pattern, 66.5mm bore and lug bolts. The RS5's fenders are wider, so S5 factory 20×9 ET34 wheels sit 12mm further in than the RS5's ET22 wheels and look tucked. RS5 20s on an S5 sit 8–12mm further out than its own wheels; owners ask about it, so check fender clearance before you commit.
