The two numbers
A bolt pattern like 5x114.3 tells you two things: the first number is how many lug holes the wheel has, and the second is the diameter in millimetres of the circle those holes sit on. Both must match your hub exactly.
Close is not close enough
5x114.3 and 5x120 are only about 6mm apart on paper, but they do not mount safely on each other’s hubs. Common patterns include 6x139.7, 5x114.3 and 6x135. Filter by yours on the wheels page, then confirm the final specification before ordering.
