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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Ford FG Falcon XT ships from the factory on a 5x114.3 bolt pattern with a 70.5mm center bore and a 16x6.5J ET36.5 wheel. Our flush reference for the Ford FG Falcon XT is 18x8J ET35.; our maximum aggressive reference is 19x8.5J ET30. — beyond that, expect clearance issues against the fender liner without further modification.
Ford FG Falcon XT OE Wheel Specs
The Ford FG Falcon XT ships from the factory on 5x114.3 bolt pattern wheels with a 70.5mm center bore. The stock wheel size is 16x6.5J ET36.5, 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 FG Falcon XT owners run 18x8J 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 19x8.5J ET30. H&R Sport springs; 18x8.0J ET35 Vossen wheels; standard brakes; Goodyear Eagle F1 245/40 R18 tires. Clearance should be verified before ordering, especially on lowered cars.

Decision Guide
Offset & Backspacing Reference

- Flush 18x8J ET35: backspacing ≈ 5.88"
- Max 19x8.5J ET30: backspacing ≈ 5.93"

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.
