Wheel Tech (Offset)

[DUB EDITION]

Offset

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.

Zero Offset

The hub mounting surface is even with the centerline of the wheel.

Positive

The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

Negative

The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.

Very good info... I'm buying rims soon and this really clears it up for me. I bet if you added a little more to it you could submit it to the tech review forum.

Definitely sounds like the beginning of a Tech Review forum submission. A few things to add, the offset range you listed at the bottom is for RWD 300's. The AWD have a different offset.

Every time I read about offset, I often get confused as to which offset moves the wheels further out vs further in. This might be good info to add (ie, a +15 offset would move the wheels further in or further out than +18 offset - once again, I have forgotten which way it moves them).

What ya say vvv90? Is this info worthy of the tech section? I vote yes!
