Club Car Golf Cart Wheel Bolt Pattern
A Club Car golf cart wheel bolt pattern is the arrangement of lugs or studs on the hub that determines which wheels can be mounted safely. Getting this measurement right matters because an incorrect pattern can distort the wheel, overload the fasteners, or let the rim sit off-center. Cart owners often check this specification before replacing a damaged wheel, upgrading to street-style tires, or fitting aftermarket rims. The pattern is usually described by lug count and the pitch circle diameter across the bolt circle, but hub fit and offset also affect whether a wheel actually seats correctly.
Essential answer
Club Car has used a four-lug hub on many of its common golf cart models, so owners frequently describe the fitment as a 4 on 4 pattern, meaning four lugs arranged on a four-inch bolt circle. That general description helps narrow a search, but it is not a complete replacement for measuring the specific cart because production changes and aftermarket hubs can alter the lug count or pitch circle diameter. The bolt pattern is only one part of wheel compatibility; the center hole and the shape of the lug seat also determine whether the rim centers on the hub and holds torque.
When you inspect a wheel, the bolt circle is not measured from adjacent studs. It is found by measuring across the center of the hub to the center of the opposite stud on a four-lug pattern, which gives the pitch circle diameter directly. If a hub has been changed or a lift kit installed, the replacement hub may carry a different bolt circle, so the original cart year alone is not always enough. Checking the actual hub, the wheel's center bore, and the lug nut seat before buying rims avoids the common problem of a wheel that bolts on but does not seat flat or run true.
