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.
Chrysler Aspen OE Wheel Specs
The 2007 Chrysler Aspen (SUV) uses a 5x139.7 bolt pattern with a 77.8mm center bore. Factory wheels are 18x8J at ET25.4.
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 with minimal rubbing, 20x9J ET20 is the recommended starting point on a stock or mildly lowered Chrysler Aspen.
Maximum Aggressive Fitment
22x10J ET15 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: 18x8J ET25.4 → ~5.5″ backspacing
- Flush: 20x9J ET20 → ~5.79″ backspacing
- Max: 22x10J ET15 → ~6.09″ backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Chrysler spec, or want a wheel built to a custom offset for your Chrysler Aspen? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
