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.
Infiniti M35h GT OE Wheel Specs
The 2013 Infiniti M35h GT (Sedan) uses a 5x114.3 bolt pattern with a 66.1mm center bore. Factory wheels are 18x8J at ET43.
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, 20x9J ET32 is the recommended starting point on a stock or mildly lowered Infiniti M35h GT.
Maximum Aggressive Fitment
20x10J ET28 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 ET43 → ~6.19″ backspacing
- Flush: 20x9J ET32 → ~6.26″ backspacing
- Max: 20x10J ET28 → ~6.6″ 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 Infiniti spec, or want a wheel built to a custom offset for your Infiniti M35h GT? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
