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
Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Mercedes-Benz ML350 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 ML350. 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 ML350 OE Wheel Specs
The 2006 Mercedes-Benz ML350 (Luxury SUV) 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:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
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 ML350.
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.

Real-World Reference Cases
The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
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 ML350? 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: 150 Nm (110 ft-lb). SUV/crossover platforms (GLC/ML/GLE/GL/GLS and similar) generally use the longer 45mm 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.
