Racing wheels On steering wheels for cars utilizing bolt circles, this usually measures 6×70 mm. Some racing wheels attach to the car via a quick release hub, and this hub then usually has a corresponding bolt circle of 6×70 mm. Example of other less used patterns include: 3×1.75 in (44.45 mm), 5×2.75 in (69.85 mm), 6×74 mm and 6×2.75 in (69.85 mm). An example of a bolt circle is 5×100 which indicates 5 nuts placed on a circle with a diameter of 100 mm. Some of the most common bolt circle diameters on modern cars are 100 mm, 112 mm and 114.3 mm. The bolt circle of a car is one of several parameters that must be checked before buying new rims to make sure they will fit the car (along with wheel offset, hub diameter, and finally the diameter and width of the rim and tire). Over the years, over 30 different bolt circles patterns have been used by car manufacturers, most of which are not compatible with each other. == See also ==
