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.
Ford Explorer ST Sinister Package OE Wheel Specs
The 2027 Ford Explorer ST Sinister Package (SUV) uses a 5x114.3 bolt pattern with a 70.5mm center bore. Factory wheels are 21x9.0J at ET45 offset, front and rear.
Why the factory spec works for most owners:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
Flush Fitment
For a flush look, a 22x10.0J wheel at ET35 offset (front and rear) is a commonly used starting point — clearance must be verified on a stock or mildly lowered Ford Explorer ST Sinister Package.
Maximum Aggressive Fitment
22x10.5J at ET30 offset is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 21x9.0J ET45 → ~6.77" backspacing
- Flush: 22x10.0J ET35 → ~6.88" backspacing
- Max: 22x10.5J ET30 → ~6.93" backspacing
