Axle Pad or Hub Fl**ge:
The area of a wheel where it contacts a car.

Bolt pattern or lug pattern or bolt circle:
These refer to the number of fasteners (lug studs) and diameter of the circle on which they are positioned. (5x4.5” would be “five by four and one-half.”)

Outer Rim:
The outermost part of a wheel. It is the area where a tire is mounted.

Center Cap:
The wheel part that covers the center bore of the wheel on the outer face of the wheel.

Wheel Center:
The portion of a wheel that consists of the axle mounting pad and the spokes.

Drop Center:
Is the smallest inside diameter area of the outer barrel of a wheel. It is used to facilitate the installation of a tire onto a wheel. Additionally, it is used as an area for placing a center disc for some 2-piece wheels during the manufacturing process.

Back Space or Rear Space:
The distance from the axle pad to the outer most edge on the backside of the wheel.

Front Space:
The distance from the axle pad to the outer most edge on the frontside of the wheel.

Hub Diameter or Center Bore:
This is the size of the hole in the center of a wheel.

Offset:
The distance +/- from wheel centerline, indicated in millimeters.

Negative Offset:
When the axle pad of the wheel is closer to the inner (car underside) edge plane.

Positive Offset:
When the axle pad of the wheel is closer to the outer (street side) edge plane.

Zero Offset:
A situation when both the back spacing and front spacing are equal. The axle fl**ge is centered between the outer edge plane and inner edge plane.

Wheel Stud or Lug Stud or Axle Bolt:
The “BOLT” portion of the wheel-fastening device. It is what the “lug nut” threads onto.

Lug Nut or Wheel Nut:
The “NUT” portion of the wheel-fastening device. It treads onto a lug stud.

Wheel Size:
The portion of the wheel that reflects what size tire it can accomidate. Not the overall size of the wheel. Usually used when talking about a wheel size. (15x7”, 16x8”, 17x7”, Etc.)

For example, a 8" wide wheel with 4" backspace, will have a frontspace of 5".
