Audi R8 Gen 1 (2008-2015) Wheel Fitment Guide
The first-generation Audi R8 uses a 5×112 bolt pattern, a 57.1mm center bore front and rear and M14×1.5 ball-seat lug bolts, with staggered factory 19s at ET42 front and ET50 rear. This guide covers US-market 2008–2015 V8, V10, V10 plus and GT coupes and Spyders: factory wheels, documented 19- to 21-inch builds and how far each sits outside stock.
About this guide: Fitment data is compiled from owner builds on R8Talk 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.

Applies ToR8 Gen 1, all years (Audi winter-approved set)
Audi lists this Avus silver set as approved for winter tires, with a narrower 10.5-inch rear at ET55 (420601025AC front, AJ rear). Its rear lip sits about 11mm inside the factory 11-inch wheel, which leaves extra room for winter tires and chains. The front matches the factory size.
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 8.5J ET42 front and 11J ET50 rear wheels, including on 20- and 21-inch cards. Every factory Gen 1 wheel is staggered, and so is every carded build.

Platform-specific fitment notes — Audi R8 Gen 1
Rear 57.1mm hub and Gen 2 wheels.
Gen 1 rear hubs are 57.1mm, while the 2017-and-later R8 uses a larger rear bore, so Gen 2 wheels and some R8-specific aftermarket rears need centering rings on a Gen 1. FMB bores every set to your car's hub, front and rear.
Front tire size and the wheel well.
An owner on 20×9 ET35 with taller 245/35R20 front tires reports light front rubbing at stock height, while 245/30R20 fronts are documented without it. Builds well outside the factory lips, such as 20×9 ET25, were fitted with camber plates and lower tie rods.
Lug bolts.
The factory bolts are M14×1.5 with a ball (radius) seat. FMB machines R8 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 Gen 1's most-asked-about 20-inch setup and the size owners most often point new buyers to. ET35 front with ET42–ET48 rear fills both arches, usually on 245/30R20 and 325/25R20. One stock-height owner on taller 245/35R20 fronts reports light front rubbing, so 245/30 is the safer front tire.

Stays on 19s but adds an inch of rear rim for a 325/30R19, the setup Gen 1 owners use when they want more tire without 20s. Near-factory offsets keep everything tucked inside the arch, while ET35 front with ET47 rear brings both lips out to flush.

Factory widths moved to 20 inches, the most conservative 20-inch setup documented. At ET38 / ET40 the lips sit only a few millimeters outside the factory 19s. The documented car runs 295/30R20 rears, a larger rolling diameter gap than stock, on a car converted to rear drive, so check the math on an all-wheel-drive car.

Half an inch wider up front with the factory rear width, built around 245/35R19 and 305/30R19 for more grip. A vendor guide lists it as fitting with street tires, and the documented car runs it on coilovers with a little negative camber. Gen 1 rear hubs are 57.1mm, so the rear wheel is bored to match.

The factory sizes with the faces moved out. ET29–ET30 front and ET32–ET35 rear bring the lips 12–18mm outside the factory wheels, on factory tire sizes or 245/305s. Both documented cars are on coilovers, so plan on a modest drop for this look.

Factory front width with a 12-inch rear in 20 inches, on 245/30R20 and 325/25R20. The front sits close to the factory position while the rear fills the arch. Only one car is documented, so treat the rear offset as a starting point to check against your ride height.

A 20-inch front with a 21-inch rear, the stagger more common on the later R8. One 2015 car runs it on lowering springs with no rubbing and a flush stance. The rear figure is measured against the factory 19-inch rear wheel, since the Gen 1 never had a 21.

A half-inch-wider rear than factory in 20 inches. The documented car runs on air suspension and lists a tucked stance, so the offsets suit a car that sits low. At stock height the same offsets would sit slightly outside the factory lips front and rear.

A wider 19-inch setup at ET35 on both axles. Two owners describe it as a good or near-perfect fit, one on a 2008 V8 with 5mm rear spacers on ET40 wheels. The rear lip sits about 21mm outside the factory wheel, the most outboard 19-inch setup in the guide.

A narrower-than-factory rear in 20 inches. With a 305 rear tire on a 10-inch rim, the documented car keeps close to the factory rolling diameter. The low front offset puts the front lip about 21mm outside the factory wheel, while the rear sits closer to stock.

Our Process
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 Gen 1 R8 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 Gen 1 R8 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 R8: 5×112 bolt pattern, bored to the 57.1mm 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.

FAQ — Frequently Asked Questions
What wheels come stock on the first-generation Audi R8?
Every US Gen 1 R8 from 2008 to 2015 came on staggered 19s: 19×8.5 ET42 front and 19×11 ET50 rear, on 235/35R19 and 295/30R19 tires. The design changes by trim, from the V8's 5-double-spoke to the V10's 10-Y-spoke and the V10 plus and GT wheels, but the sizes and offsets stay the same.
What are the Gen 1 R8's bolt pattern, center bore and lug specs?
The Gen 1 uses a 5×112 pattern, a 57.1mm center bore front and rear and M14×1.5 ball-seat lug bolts, torqued to 120 Nm (89 lb-ft) per Audi's wheel-bolt table. FMB machines R8 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 a Gen 1 R8 at stock ride height?
Documented at stock height: 20×9 ET35 front with 20×11 ET38 rear on 245/30R20 and 305/30R20, 20×8.5 ET38 / 20×11 ET40, and 20×9 ET35 / 20×12 ET45, where taller 245/35 fronts rubbed lightly. A vendor guide lists 19×9 ET34 / 19×11 ET38 with street tires. Most other builds are on coilovers or springs.
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 8.5J ET42 front and 11J ET50 rear. Most builds sit 10–18mm out; 20×9 ET25 front and rear sits 23–25mm out, the aggressive end.
Do aftermarket wheels clear the Gen 1 R8's brakes?
Steel brakes use 365mm front rotors with eight-piston calipers; carbon-ceramics, standard on the V10 plus and GT, use 380mm rotors with six-piston calipers. Every documented build here is 19 inches or larger, and a vendor lists its 19-inch R8 sizes as clearing the factory brakes. Spoke shape still matters, so tell us your brake package.
Should I run a square or staggered setup on a Gen 1 R8?
Audi fitted staggered wheels to every Gen 1 R8, and every documented build keeps a wider rear. A square setup would mean a much narrower rear tire or a wide front that crowds the front arch, and we found no owner running one. Staggered setups also keep the factory front-to-rear tire balance.
Does tire size matter for the Gen 1 R8's quattro drive?
Yes. 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. One documented 20-inch car runs a 4% gap, but it was converted to rear drive.
Can I use wheel spacers on a Gen 1 R8?
Many owners run 10–15mm spacers on factory 19s, and one V8 owner used 5mm rear spacers on ET40 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 Gen 1 R8?
Audi approved a winter set with a 19×8.5 ET42 front and a narrower 19×10.5 ET55 rear, sold as the 5-double-spoke design in Avus silver. Owners also fit winter tires on the factory 19s. The narrower rear sits about 11mm inside the factory wheel, which gives winter tires more room in the rear arch.
Which Gen 1 R8 model years does this guide cover?
US-market Type 42 R8s from 2008 through 2015: V8 coupe from 2008, V10 from 2010, Spyders from 2011, the 2012–2013 GT and the 2014–2015 V10 plus. The 2014 facelift kept the same hubs and wheel sizes. The second-generation R8, sold in the US from 2017, has its own guide.
Can I put Gen 2 R8 wheels on a Gen 1, or Gen 1 wheels on a Gen 2?
They share the 5×112 pattern, M14×1.5 bolts and similar factory offsets, so wheels swap between generations with the right hub rings. Gen 2 rear wheels have a larger center bore than the Gen 1's 57.1mm rear hub, so they need centering rings on a Gen 1. Our R8 Gen 2 guide covers the later car.
