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
A minivan's wheel spec has to work across a wide load range — empty commute or full family trip. Forged construction preserves the factory's load-rating margin while cutting rotational weight, which keeps ride quality consistent across that range.
The Mercedes-Benz R500 runs a 5x112 bolt pattern, 66.6mm center bore, and a 18x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 19x9.0J ET35, which tucks the tire under the fender lip on a stock-height Mercedes-Benz R500. Our Maximum Aggressive reference is 20x9.5J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz R500 OE Wheel Specs
The 2006 Mercedes-Benz R500 (Luxury MPV) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are 18x8.0J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
Flush Fitment
For a flush look with minimal rubbing, F/R 19x9.0J ET35 is the recommended starting point on a stock or mildly lowered Mercedes-Benz R500.
Maximum Aggressive Fitment
F/R 20x9.5J ET30 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: 18x8.0J ET45
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: 19x9.0J ET35
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: 20x9.5J ET30
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x8.0J ET45 → ~6.27″ backspacing
- Flush: 19x9.0J ET35 → ~6.38″ backspacing
- Max: 20x9.5J ET30 → ~6.43″ 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 Mercedes-Benz spec, or want a wheel built to a custom offset for your Mercedes-Benz R500? 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.
Factory Torque Spec: 130 Nm (96 ft-lb). Sedan/coupe platforms (E-Class, CLS, SL and similar) generally use the shorter 27mm bolt at this spec.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
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.
