Wheel Backspace & Offset Information
This page is intended to provide basic Original Equipment "OE" wheel size information. It is very common for a suspension lift manufacturer to recommend the use of a wheel that has LESS backspace than the Factory Wheel when running a suspension lift on your Truck or SUV. Factory wheels of the same size may be offered in different styles that could have different specifications than those listed below. You should always verify fitment information with your vehicle manufacturer and wheel company before purchasing new wheels.
Remember these rules:
As positive offset increases wheel backspace increases.
As wheel offset is decreased wheel backspace decreases.
If you want a narrow stance you want a wheel with MORE backspace.
If you want a wider stance you want a wheel with LESS backspace.
