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
Trucks live and die on unsprung weight and load capacity — every pound added at the wheel is a pound the suspension has to control over every bump, fully loaded or not. Forging the wheel instead of casting it lets us hold the factory load rating while cutting rotational mass, which pays off directly in ride quality and steering response on a vehicle that spends real time towing or hauling.
The BYD Shark ships from the factory on a 6x139.7 bolt pattern with a 106.1mm center bore and a 18x8J ET45 wheel. Our flush reference for the BYD Shark is 18x9J ET18.; our maximum aggressive reference is 20x9J ET12. — beyond that, expect clearance issues against the fender liner without further modification.
BYD Shark OE Wheel Specs
The BYD Shark ships from the factory on 6x139.7 bolt pattern wheels with a 106.1mm center bore. The stock wheel size is 18x8J ET45, 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 BYD Shark owners run 18x9J ET18. 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 20x9J ET12. Method Race Wheels MR316 18x9.0J ET18 Matte Black with Goodyear Wrangler All-Terrain Clearance should be verified before ordering, especially on lowered cars.
