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.
Cadillac CT5-V Blackwing F1 Collector Series OE Wheel Specs
The 2026 Cadillac CT5-V Blackwing F1 Collector Series (Sedan) uses a 5x120 bolt pattern with a 66.9mm center bore. Factory wheels are F 19x10.0J ET32 / R 19x11.0J ET45.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
Flush Fitment
For a flush look with minimal rubbing, F 19x10.5J ET25 / R 19x11.5J ET40 is the recommended starting point on a stock or mildly lowered Cadillac CT5-V Blackwing F1 Collector Series.
Maximum Aggressive Fitment
F 20x10.5J ET22 / R 20x12.0J ET35 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 (F): 19x10.0J ET32 → ~6.76″ backspacing
- OE (R): 19x11.0J ET45 → ~7.77″ backspacing
- Flush (F): 19x10.5J ET25 → ~6.73″ backspacing
- Flush (R): 19x11.5J ET40 → ~7.82″ backspacing
- Max (F): 20x10.5J ET22 → ~6.62″ backspacing
- Max (R): 20x12.0J ET35 → ~7.88″ backspacing
