A stud pattern is written as two numbers, for example 5x120. The first is how many studs or bolt holes your hub has. The second is the diameter, in millimetres, of the circle that runs through the centre of them. You'll also see it called the bolt pattern, lug pattern or bolt circle. They all mean the same thing.
PCD is set by the van, not the wheel. Every wheel is drilled to a specific pattern, and a wheel with the wrong PCD won't bolt on safely, however good it looks in a photo. Some Rogue wheels are drilled for two patterns, shown as 5x100/108.
Two patterns are often shortened. 5x114.3 is usually written 5x114, and 6x139.7 is usually written 6x139. Same pattern, same wheels.
The easy way: pick your van and we only show wheels in your stud pattern. There's nothing to measure unless you want to check.
