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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Ford Windstar ships from the factory on a 5x108 bolt pattern with a 63.4mm center bore and a 15x6J ET44 wheel. Our flush reference for the Ford Windstar is 17x7.5J ET38.; our maximum aggressive reference is 18x8J ET35. — beyond that, expect clearance issues against the fender liner without further modification.
Ford Windstar OE Wheel Specs
The Ford Windstar ships from the factory on 5x108 bolt pattern wheels with a 63.4mm center bore. The stock wheel size is 15x6J ET44, 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 Windstar owners run 17x7.5J ET38. 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 18x8J ET35. Lowering springs; 17x7.5J ET38 BBS SR wheels; standard brakes; Michelin Defender LTX 225/60 R17 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 15x6J ET44: backspacing ≈ 5.23"
- Flush 17x7.5J ET38: backspacing ≈ 5.75"
- Max 18x8J ET35: backspacing ≈ 5.88"

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: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
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.
