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 ships from the factory on a 4x108 bolt pattern with a 63.4mm center bore and a 14x5.5J ET35 wheel. Our flush reference for the Ford Ka is 15x6.5J ET35.; our maximum aggressive reference is 16x7J ET32. — beyond that, expect clearance issues against the fender liner without further modification.
Ford Ka OE Wheel Specs
The Ford Ka ships from the factory on 4x108 bolt pattern wheels with a 63.4mm center bore. The stock wheel size is 14x5.5J ET35, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
Flush Fitment
For a flush look without any body modification, most Ford Ka owners run 15x6.5J ET35. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
Maximum Aggressive Fitment
Owners chasing a more aggressive stance push to 16x7J ET32. Eibach lowering springs; 15x6.5J ET35 ENKEI wheels; standard brakes; Michelin Pilot Sport 3 195/50 R15 tires. Clearance should be verified before ordering, especially on lowered cars.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.
- OE 14x5.5J ET35: backspacing ≈ 4.63"
- Flush 15x6.5J ET35: backspacing ≈ 5.13"
- Max 16x7J ET32: backspacing ≈ 5.26"

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.
