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 GLA-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 GLA-Class runs a 5x112 bolt pattern, 66.6mm center bore, and a 17x6.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x7.5J ET38, which tucks the tire under the fender lip on a stock-height Mercedes-Benz GLA-Class. Our Maximum Aggressive reference is 19x8.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz GLA-Class OE Wheel Specs
The 2015 Mercedes-Benz GLA-Class (Crossover) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are 17x6.5J 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 GLA-Class (2015) 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.

Flush Fitment
For a flush look with minimal rubbing, F/R 18x7.5J ET38 is the recommended starting point on a stock or mildly lowered Mercedes-Benz GLA-Class.
Maximum Aggressive Fitment
F/R 19x8.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Mercedes-Benz GLA-Class owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x6.5J ET43 → ~5.44″ backspacing
- Flush: 18x7.5J ET38 → ~5.75″ backspacing
- Max: 19x8.0J ET35 → ~5.88″ 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 GLA-Class? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Mercedes-Benz GLA-Class (2015)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x112 pattern and the 66.6mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Mercedes-Benz orders on this platform land somewhere between the 18x7.5J ET38 flush setup and the 19x8.0J ET35 aggressive setup referenced above.

What bolt pattern (PCD) does the Mercedes-Benz GLA-Class use?
The 2015 Mercedes-Benz GLA-Class uses a 5x112 bolt pattern.
How many lug bolts does the Mercedes-Benz GLA-Class use?
The Mercedes-Benz GLA-Class 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 GLA-Class?
The Mercedes-Benz GLA-Class'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 GLA-Class?
Factory wheels on the Mercedes-Benz GLA-Class are 17x6.5J F/R.
What is the biggest wheel size I can fit on my Mercedes-Benz GLA-Class without rubbing?
The most aggressive fitment we recommend without fender work is 19x8.0J at ET35 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 GLA-Class?
For a flush look with minimal to no rubbing, we recommend 18x7.5J at ET38 offset as a starting point on a stock or mildly lowered Mercedes-Benz GLA-Class.
Do I need wheel spacers for my Mercedes-Benz GLA-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 GLA-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 5.75" 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 GLA-Class?
The Mercedes-Benz GLA-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.
Vehicles With the Same Hub as the Mercedes-Benz GLA-Class (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.

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.
