Today, we’re going to review part number AM31208. This is the Kenda 145R12 radial trailer tire
mounted on a 12″ HWT aluminum wheel. We’ll start with the rim dimension. This is a 12″ diameter wheel, which if we
measure from inside-to-inside would be 12″. The width of this wheel is 4″ wide. This wheel has a bolt pattern of 4 lugs 4″
bolt pattern. The way to measure that is from the center
of one lug hole directly across to the center of the opposite lug hole would be 4″. The weight capacity on this wheel is 1,220
pounds at 80 psi. This wheel uses a bolt size of 1/2″-20. Then other critical measurement is the pilot
hole diameter, which is this large hole at the center of the wheel. That will go over
the hub on your trailer.
