Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |

How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
On a performance-oriented coupe, the wheel is one of the few components where shaving weight has a compounding effect — less rotational mass means less work for the brakes, the drivetrain, and the chassis on every input. A forged wheel gets there without compromising the strength margin the factory engineered in.
The Audi S5 runs a 5x112 bolt pattern, 66.5mm center bore, and a 19x8.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET25, which tucks the tire under the fender lip on a stock-height Audi S5. Our Maximum Aggressive reference is 20x9.5J ET20 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Audi S5 OE Wheel Specs
The 2012 Audi S5 (Coupe) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are 19x8.5J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
Flush Fitment
For a flush look with minimal rubbing, F/R 20x9.0J ET25 is the recommended starting point on a stock or mildly lowered Audi S5.
Maximum Aggressive Fitment
F/R 20x9.5J ET20 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 19x8.5J ET35 → ~6.13″ backspacing
- Flush: 20x9.0J ET25 → ~5.98″ backspacing
- Max: 20x9.5J ET20 → ~6.04″ backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Audi spec, or want a wheel built to a custom offset for your Audi S5? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, ball-seat lug bolt (13mm radius).
Factory Torque Spec: 120 Nm (89 ft-lb). Shared VW/Audi Group ball-seat bolt spec used across most 5x112 Audi models.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
