The combat rim, also called the run flat rim, has an outer ring that bolts onto the wheel. This rim was used on WWII Dodge WC 3/4 ton trucks.
The split ring rim has a ring that is forced over the rim and interlocks with it. The WWII 1/2 Dodge WC 1/2 ton trucks, M37 and WDX pattern Power Wagons used this type of a rim.
The extra 10 pounds of weight of the combat rims over the split ring rims of the same size is due to a slightly heavier ring, plus the 10 extra bolts and nuts to hold the rim on.
