Positive offset creates more backspace, while negative offset reduces backspace. The example shown here is 6 inches wide with a 3 inch backspacing. This would be the equivalent to a zero offset wheels since the mounting surface aligns with the centerline of the wheel.
Many vehicle owners like the aggressive look of a negative offset, but it can be an issue on some vehicles. Backspacing is the cousin of offset. Backspacing is the amount usually measured in inches of distance that the mounting surface of the wheel is away from the inner edge of the wheel. Backspacing is usually a positive number, but in certain circumstances, like on a dually pickup truck, it can be negative. The amount of backspacing a wheel has can significantly alter the position of the wheel on a vehicle.
For example, on a Ford F, the stock 18x8 inch wheels has a 6. This wheel backspacing is good for a stock sized tire, and keeps the wheel and tire combination inside the fender. Many aftermarket wheels will have a different backspacing- for example, and 18x9 Fuel Hostage could have a 5. By this point the wheel manufacturers would stamp on the mounting pad the offset and begin to use the offset term as a primary reference.
The stamp would like something like this 8. By the s more vehicles were being manufactured that required high offset wheels and the term offset begun to gain traction over backspacing.
As of today backspacing and even front spacing are truly the most important variables in custom wheel manufacturing where a precision fitment is a must. However for the cast wheel industry and a greater portion of the factory and aftermarket wheels being produced offset is going to be the measurement primarily referenced.
The offset of the wheel is a measurement taken from the centerline of the wheel to the mounting pad of the wheel. The higher the offset the closer the wheel is to your chassis. If you used our Search By Vehicle tool we will only show you offset ranges that are within range for your vehicle.
For Cars: The offset ranges offered will result in wheels that will never stick out of your fenders. If you prefer a Flush with the fender look a lower offset will help achieve that. For Trucks: The offset ranges offered will result in either a flush or slight poke look. If you prefer for the wheels not to poke outside the fenders look for the highest offset available.
Depending on your lift and the size of the tire required, the offset ranges offered will result in either a flush look or in some cases will stick outside the fenders. The larger the lift and tire size required the more the wheels will sit outside the fenders.

Positive wheel offset is when the hub mounting surface is in front more toward the street side of the centerline of the wheel.
Most wheels on front-wheel drive cars and newer rear-drive vehicles have positive offset. Negative offset is when the hub mounting surface is behind the wheel centerline. Getting them wrong can mean big problems. Offset measurements can be tricky.
