Second Generation (1994-2001; BR/BE)
The second generation of the Dodge RAM 1500 pickup truck (1994-2001; BR/BE) comes in two trims: WS and ST, SLT, SLT+, and Laramie .

The WS trim has a wheel offset range of 29.8mm to 33.8mm, which is the distance between the hub mounting surface and the centerline of the wheel. The thread size for the lug nuts is 1/2″ – 20 UNF, which means that they have a 1/2-inch diameter and 20 threads per inch, using a unified national fine thread.
The center bore, which is the diameter of the hole in the center of the wheel that fits over the hub, is 77.8mm. The recommended rim size for the WS trim is 16 inches.
The ST trim has a slightly lower wheel offset range of 23.4mm to 27.4mm and a recommended rim size of 17 inches. The other specifications for the lug nuts, bolt pattern, and center bore are the same as the WS trim.
