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
Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Kia Stonic [UK] runs a 4x100 bolt pattern, 54.1mm 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 Kia Stonic [UK]. Our Maximum Aggressive reference is 18x8.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Kia Stonic [UK] OE Wheel Specs
The 2018 Kia Stonic [UK] (Crossover) uses a 4x100 bolt pattern with a 54.1mm center bore. Factory wheels are 17x6.5J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Kia Stonic [UK] (2018) we drill the 4x100 pattern and cut the centre bore to 54.1mm 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 18x7.5J ET38 is the recommended starting point on a stock or mildly lowered Kia Stonic [UK].
Maximum Aggressive Fitment
F/R 18x8.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Kia Stonic [UK] owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 17x6.5J ET45 → ~5.52″ backspacing
- Flush: 18x7.5J ET38 → ~5.75″ backspacing
- Max: 18x8.0J 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 Kia spec, or want a wheel built to a custom offset for your Kia Stonic [UK]? 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 Kia Stonic [UK] (2018)
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 4x100 pattern and the 54.1mm 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 Kia orders on this platform land somewhere between the 18x7.5J ET38 flush setup and the 18x8.0J ET35 aggressive setup referenced above.

What bolt pattern (PCD) does the Kia Stonic [UK] use?
The 2018 Kia Stonic [UK] uses a 4x100 bolt pattern.
How many lug bolts does the Kia Stonic [UK] use?
The Kia Stonic [UK] uses a 4-lug bolt pattern (4x100), so you need a 4-lug forged wheel to bolt straight on.
What is the center bore size on the Kia Stonic [UK]?
The Kia Stonic [UK]'s center bore is 54.1mm. 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 Kia Stonic [UK]?
Factory wheels on the Kia Stonic [UK] are 17x6.5J F/R.
What is the biggest wheel size I can fit on my Kia Stonic [UK] without rubbing?
The most aggressive fitment we recommend without fender work is 18x8.0J 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 Kia Stonic [UK]?
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 Kia Stonic [UK].
Do I need wheel spacers for my Kia Stonic [UK]?
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 Kia Stonic [UK]?
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 Kia Stonic [UK]?
The Kia Stonic [UK] 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: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 107-127 Nm (79-94 ft-lb). Range covers most Kia passenger cars and crossovers 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.
