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

SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.

The Mercedes-Benz G550 [US] runs a 5x130 bolt pattern, 84.1mm center bore, and a 20x8.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 22x9.5J ET25, which tucks the tire under the fender lip on a stock-height Mercedes-Benz G550 [US]. Our Maximum Aggressive reference is 22x10.0J ET20 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.

Mercedes-Benz G550 [US] OE Wheel Specs

The 2025 Mercedes-Benz G550 [US] (Off-Road SUV) uses a 5x130 bolt pattern with a 84.1mm center bore. Factory wheels are 20x8.5J 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 G550 [US] (2025) 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.

Flush Fitment

For a flush look with minimal rubbing, F/R 22x9.5J ET25 is the recommended starting point on a stock or mildly lowered Mercedes-Benz G550 [US].

Maximum Aggressive Fitment

F/R 22x10.0J ET20 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

  • OE: 20x8.5J ET35 → ~6.13″ backspacing
  • Flush: 22x9.5J ET25 → ~6.23″ backspacing
  • Max: 22x10.0J ET20 → ~6.29″ 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 G550 [US]? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Vehicles With the Same Hub as the Mercedes-Benz G550 [US] (5x130, 84.1 mm Bore)

In our database, 34 other vehicle entries from 3 makes use exactly the same 5x130 bolt pattern and 84.1 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.

5x130 is used by 5.8% of the vehicle pages in our English fitment guide (375 of 6,503); 9.3% of those also use a 84.1 mm center bore.

Hub-Centric Rings for a 84.1 mm Center Bore

A wheel with a center bore larger than 84.1 mm needs a hub-centric ring. The most common combinations:

Wheel boreRing size
93.1 mm93.1 → 84.1 mm
100.1 mm100.1 → 84.1 mm
106.1 mm106.1 → 84.1 mm
108.1 mm108.1 → 84.1 mm

ANKUSI forged wheels are bored to exactly 84.1 mm for this vehicle, so no ring is needed.

Frequently Asked Questions

What bolt pattern (PCD) does the Mercedes-Benz G550 [US] use?
The 2025 Mercedes-Benz G550 [US] uses a 5x130 bolt pattern.
How many lug bolts does the Mercedes-Benz G550 [US] use?
The Mercedes-Benz G550 [US] 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 G550 [US]?
The Mercedes-Benz G550 [US]'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 G550 [US]?
Factory wheels on the Mercedes-Benz G550 [US] are 20x8.5J F/R.
What is the biggest wheel size I can fit on my Mercedes-Benz G550 [US] without rubbing?
The most aggressive fitment we recommend without fender work is 22x10.0J at ET20 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 G550 [US]?
For a flush look with minimal to no rubbing, we recommend 22x9.5J at ET25 offset as a starting point on a stock or mildly lowered Mercedes-Benz G550 [US].
Do I need wheel spacers for my Mercedes-Benz G550 [US]?
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 G550 [US]?
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 6.23" 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 G550 [US]?
The Mercedes-Benz G550 [US] 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.
