Bolt pattern correction
The bolt pattern of a wheel is given, in say, 5 on 100 mm, means it is 100 milimeters across the face of an imaginary circle drawn through the center of the bolt holes. It is not as simple as some people think, by saying it is 100 milimeters apart, this can be way off on some vehicles, such as 5 or 6 lug vehicles, so make sure the pattern is correct for your vehicle, especially on some newer vehicles, like the ones that use 5 on 143.5 mm, or 5 on 144 mm, as these 2 are close, but are NOT interchangeable, and I have seen many auctions using them interchangably, as this could cause a bad balance if wrong.
