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
The Mercedes-Benz G-Class's factory suspension tuning already accounts for a specific unsprung mass target. Forged construction lets ANKUSI match the factory strength spec while keeping rotational weight down, which is where the real handling benefit comes from on a taller, heavier SUV platform.
The Mercedes-Benz G-Class runs a 5x130 bolt pattern, 84.1mm center bore, and a 18x7.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET30, which tucks the tire under the fender lip on a stock-height Mercedes-Benz G-Class. Our Maximum Aggressive reference is 22x9.5J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz G-Class OE Wheel Specs
The 2009 Mercedes-Benz G-Class (Off-Road SUV) uses a 5x130 bolt pattern with a 84.1mm center bore. Factory wheels are 18x7.5J 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
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Mercedes-Benz G-Class (2009) we drill the 5x130 pattern and cut the centre bore to 84.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x7.5J ET35 → ~5.63″ backspacing
- Flush: 20x9.0J ET30 → ~6.18″ backspacing
- Max: 22x9.5J ET25 → ~6.23″ 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 G-Class? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Mercedes-Benz G-Class use?
The 2009 Mercedes-Benz G-Class uses a 5x130 bolt pattern.
How many lug bolts does the Mercedes-Benz G-Class use?
The Mercedes-Benz G-Class uses a 5-lug bolt pattern (5x130), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Mercedes-Benz G-Class?
The Mercedes-Benz G-Class's center bore is 84.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Mercedes-Benz G-Class?
Factory wheels on the Mercedes-Benz G-Class are 18x7.5J F/R.
What is the biggest wheel size I can fit on my Mercedes-Benz G-Class without rubbing?
The most aggressive fitment we recommend without fender work is 22x9.5J at ET25 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Mercedes-Benz G-Class?
For a flush look with minimal to no rubbing, we recommend 20x9.0J at ET30 offset as a starting point on a stock or mildly lowered Mercedes-Benz G-Class.
Do I need wheel spacers for my Mercedes-Benz G-Class?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Mercedes-Benz G-Class?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.18" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Mercedes-Benz G-Class?
The Mercedes-Benz G-Class runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
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: 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.
