Bolt Pattern
The bolt pattern of a vehicle describes the way in which the lug nuts are arranged to secure the wheel onto the wheel hub. The first digit represents the number of lug nut holes. The second digit represents the diameter of the circle that the lug nuts create. A bolt pattern of 4x100 would mean that there are 4 holes to fit lug nuts into and that they are 100mm apart. Many cars now have the capability to fit multiple lug patterns by drilling extra holes. It is possible to measure your own vehicle's bolt pattern but an odd number of bolts will require either a bolt pattern gauge or some basic geometry math.
Wheel Offset
To understand wheel offset, you must draw a line through the center of the wheel's width when looking at it from the side. There will be a mounting surface where the wheel will be screwed onto the hub. If the mounting surface is directly aligned with the center of the wheel, then this is called zero offset. If the mounting surface of the wheel is further away from the car from the centerline then this is called positive offset. Positive offset will cause your wheels to be sucked in to the car. Finally, when the mounting surface of the wheel is closer to the car from the centerline this is negative offset and will cause the tire to stick out away from the vehicle.
L = Low Offset or RWD (Rear Wheel Drive). Sometimes referred to as zero offset because it is typically 0 offset.
M = Medium Offset or RWD (Rear Wheel Drive). Slightly higher offset than Low Offset, typically +20 offset.
H = High Offset or FWD (Front Wheel Drive). Can be in the range of +45, +40, +35 offset.
Center Bore
There is a hole in the center of all wheels that will fit over a cylinder jutting out of the wheel hub. Most wheels have a larger than needed center bore in order to fit more vehicles. In this case, a hub ring is required to make sure that it will fit snug. If it does not fit, the risk of unbalanced fitment is very possible. It is important to match the wheel with the hub which is called being hub centric. If you do not have hub centric wheels when you install them the weight of the car will cause them to become slightly off center. This can be minimized by taking the car off the ground, but the best solution is always to make sure your wheels are hub centric with your car.
