Or lug pattern, or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4, 5, 6 or 8 lug holes. The bolt pattern is comprised of two numbers - the first indicates how many bolt holes are on the wheel, and the other describes how far apart they are. for example, a bolt circle of 5x108 would indicate a 5 lug bolt pattern in a circle with a diameter of 108mm.


More and more manufacturers are building their wheels with two bolt patterns. This expands the number of fitments the wheel applies to. For example: a wheel with a 4-100/114.3 bolt pattern has 8 lug holes and will fit both 4-100mm and 4-114.3mm fitments.


The distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle.

H = High Positive or FWD (Front Wheel Drive) typically +45, 40, 35 offsets

M = Medium Offset or RWD (Rear Wheel Drive) Typically +20 offset

L = Low Offset or RWD (Rear Wheel Drive) Typically 0 offset

Relates to the center hole in the wheel that centers the wheel on the hub of the car. Since most wheels are mass produced, they have a large center bore to accommodate several different vehicles. If this is the case, it is recommended that you use a hub ring. Hub rings are hard plastic or metal ring that fits between the wheel and the vehicle. This centers the wheel perfectly on the hub ensuring that there is no run out when the wheel is installed on to the vehicle. Without hub rings it is possible to get vibrations even if the wheel / tire assembly is perfectly balanced.


All alloy wheels should be installed using a torque wrench. This ensures that the wheels are not too tight or too loose. Check your vehicle's manual for correct settings. When you install wheels for the first time, you should re-torque wheels after about 100km to 150km (60 to 90 miles). Always refer to Owner's Manual for proper factory specifications that take precedence over the listed recommendations.
