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 wagon carries wagon-specific weight distribution — more mass over the rear axle when loaded — so wheel strength at the rear corners matters as much as the front. Forging lets us match the factory's strength target on both ends while keeping rotational mass down, which keeps the ride composed whether the cargo area is empty or full.
The Mercedes-Benz C-Class All-Terrain runs a 5x112 bolt pattern, 66.6mm center bore, and a 18x7.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 19x8.5J ET35, which tucks the tire under the fender lip on a stock-height Mercedes-Benz C-Class All-Terrain. Our Maximum Aggressive reference is 20x9.0J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz C-Class All-Terrain OE Wheel Specs
The 2022 Mercedes-Benz C-Class All-Terrain (Raised Wagon) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are 18x7.5J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Mercedes-Benz C-Class All-Terrain (2022) we drill the 5x112 pattern and cut the centre bore to 66.6mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x7.5J ET38 → ~5.75″ backspacing
- Flush: 19x8.5J ET35 → ~6.13″ backspacing
- Max: 20x9.0J ET30 → ~6.18″ 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 C-Class All-Terrain? 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 C-Class All-Terrain (5x112, 66.6 mm Bore)
In our database, 823 other vehicle entries from 21 makes use exactly the same 5x112 bolt pattern and 66.6 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.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 58.6% of those also use a 66.6 mm center bore.
Hub-Centric Rings for a 66.6 mm Center Bore
A wheel with a center bore larger than 66.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.6 mm |
| 70.1 mm | 70.1 → 66.6 mm |
| 70.5 mm | 70.5 → 66.6 mm |
| 71.6 mm | 71.6 → 66.6 mm |
| 73.1 mm | 73.1 → 66.6 mm |
ANKUSI forged wheels are bored to exactly 66.6 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Mercedes-Benz C-Class All-Terrain use?
The 2022 Mercedes-Benz C-Class All-Terrain uses a 5x112 bolt pattern.
How many lug bolts does the Mercedes-Benz C-Class All-Terrain use?
The Mercedes-Benz C-Class All-Terrain uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Mercedes-Benz C-Class All-Terrain?
The Mercedes-Benz C-Class All-Terrain's center bore is 66.6mm. 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 C-Class All-Terrain?
Factory wheels on the Mercedes-Benz C-Class All-Terrain are 18x7.5J F/R.
What is the biggest wheel size I can fit on my Mercedes-Benz C-Class All-Terrain without rubbing?
The most aggressive fitment we recommend without fender work is 20x9.0J at ET30 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 C-Class All-Terrain?
For a flush look with minimal to no rubbing, we recommend 19x8.5J at ET35 offset as a starting point on a stock or mildly lowered Mercedes-Benz C-Class All-Terrain.
Do I need wheel spacers for my Mercedes-Benz C-Class All-Terrain?
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 C-Class All-Terrain?
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 6.13" 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 C-Class All-Terrain?
The Mercedes-Benz C-Class All-Terrain 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: 130 Nm (96 ft-lb). Sedan/coupe platforms (E-Class, CLS, SL and similar) generally use the shorter 27mm 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.
