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
Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.
The Ford Ka plus runs a 4x108 bolt pattern, 63.4mm center bore, and a 14x5.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 15x6.5J ET40, which tucks the tire under the fender lip on a stock-height Ford Ka plus. Our Maximum Aggressive reference is 16x7.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Ford Ka plus OE Wheel Specs
The 2019 Ford Ka plus (Hatchback) uses a 4x108 bolt pattern with a 63.4mm center bore. Factory wheels are 14x5.5J F/R.
Why the factory spec works for most owners:
- Preserves the factory-tuned ride and steering feel
- A mainstream size for this segment, keeping tire choice wide and prices reasonable
- Leaves full clearance for the stock brakes and suspension hardware
- Keeps handling predictable and consistent in everyday conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Ford Ka plus (2019) we drill the 4x108 pattern and cut the centre bore to 63.4mm 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 15x6.5J ET40 is the recommended starting point on a stock or mildly lowered Ford Ka plus.
Maximum Aggressive Fitment
F/R 16x7.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases
The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: 14x5.5J ET47
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: 15x6.5J ET40
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: 16x7.0J ET35
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 14x5.5J ET47.5 → ~5.12″ backspacing
- Flush: 15x6.5J ET40 → ~5.32″ backspacing
- Max: 16x7.0J ET35 → ~5.38″ 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 Ford spec, or want a wheel built to a custom offset for your Ford Ka plus? 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 Ford Ka plus (2019)
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 4x108 pattern and the 63.4mm 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 Ford orders on this platform land somewhere between the 15x6.5J ET40 flush setup and the 16x7.0J ET35 aggressive setup referenced above.
We do not hold 4x108 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 136 Nm (100 ft-lb). Covers most Ford passenger cars and crossovers (Fusion, Focus, Escape and similar) on M12x1.5 studs.
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.
