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
Every gram of rotational mass on a supercar fights the acceleration, braking, and rotational inertia numbers the factory spent enormous engineering effort achieving. A forged wheel for the FM Auto Evantra holds the OE strength rating at meaningfully less weight, which is a real, measurable performance gain rather than a cosmetic one.
The FM Auto Evantra runs a 5x112 bolt pattern, 66.5mm center bore, and a F: 20x8.5J wheel from the factory. Our Flush Fitment reference is F 20x9.0J ET30 / R 20x11.5J ET25, which tucks the tire under the fender lip on a stock-height FM Auto Evantra. Our Maximum Aggressive reference is F 20x9.5J ET25 / R 21x12.0J ET20 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
FM Auto Evantra OE Wheel Specs
The 2012 FM Auto Evantra (Supercar) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are F: 20x8.5J R: 20x11.0J.
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 FM Auto Evantra (2012) we drill the 5x112 pattern and cut the centre bore to 66.5mm 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 20x9.0J ET30 / R 20x11.5J ET25 is the recommended starting point on a stock or mildly lowered FM Auto Evantra.
Maximum Aggressive Fitment
F 20x9.5J ET25 / R 21x12.0J 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: F 20x8.5J ET35 → ~6.13″ F backspacing, R 20x11.0J ET30 → ~7.18″ R backspacing
- Flush: F 20x9.0J ET30 → ~6.18″ F backspacing, R 20x11.5J ET25 → ~7.23″ R backspacing
- Max: F 20x9.5J ET25 → ~6.23″ F backspacing, R 21x12.0J ET20 → ~7.29″ R backspacing

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 FM Auto Evantra (2012)
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 66.5mm 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.
Designs we already tool for the 5x112 pattern — each one is re-cut to your sizes and offsets:

Mercedes-Benz OEM-Style Gloss Black Hole Disc Windowed Ring Forged Wheels – Mercedes G-Class / GLS Fitment (5-Lug)
APEX VS-5RS Matte Black 1-Piece Forged Wheels – Mercedes-AMG GT Fitment (21-22in, 5x112)

What bolt pattern (PCD) does the FM Auto Evantra use?
The 2012 FM Auto Evantra uses a 5x112 bolt pattern.
How many lug bolts does the FM Auto Evantra use?
The FM Auto Evantra 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 FM Auto Evantra?
The FM Auto Evantra's center bore is 66.5mm. 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 FM Auto Evantra?
Factory wheels on the FM Auto Evantra are F: 20x8.5J R: 20x11.0J.
What is the biggest wheel size I can fit on my FM Auto Evantra without rubbing?
The most aggressive fitment we recommend without fender work is F 20x9.5J ET25 / R 21x12.0J ET20. 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 FM Auto Evantra?
For a flush look with minimal to no rubbing, we recommend F 20x9.0J ET30 / R 20x11.5J ET25 as a starting point on a stock or mildly lowered FM Auto Evantra.
Do I need wheel spacers for my FM Auto Evantra?
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 FM Auto Evantra?
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" backspacing up front and 7.23" in the rear.
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 FM Auto Evantra?
Yes — the FM Auto Evantra's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
Vehicles With the Same Hub as the FM Auto Evantra (5x112, 66.5 mm Bore)
In our database, 167 other vehicle entries from 6 makes use exactly the same 5x112 bolt pattern and 66.5 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 entries in our database (1,407 of 6,503); 11.9% of those also use a 66.5 mm center bore.
Hub-Centric Rings for a 66.5 mm Center Bore
A wheel with a center bore larger than 66.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.6 mm | 66.6 → 66.5 mm |
| 67.1 mm | 67.1 → 66.5 mm |
| 70.1 mm | 70.1 → 66.5 mm |
| 70.5 mm | 70.5 → 66.5 mm |
| 73.1 mm | 73.1 → 66.5 mm |
ANKUSI forged wheels are bored to exactly 66.5 mm for this vehicle, so no ring is needed.
