RAM Hub Bore

Hub center bore is the hole at the middle of the wheel on the hub of your RAM. Two basic parameters influence the centric rim size: a center bore and an outside diameter of the wheel hub.

Practically, the manufacturers don’t mark any center bore specifications on the rim. If you buy a new rim for your RAM, you can find the values in the instructions or ask the rim dealer. Otherwise, you need to measure the center bore by the ruler yourself. Also, you may use a tape measure. Gauge the center bore diameter and mark its value on the paper. Then you need to go to the stock and find out a rim with the same or a bit larger center bore diameter than you have just measured.
