I suspect the range isn't that great but hopefully someone will have the answer before I buy the wrong rims.
The range of years really has nothing to do with it prior to 1999. You need wheels that have the correct center hole size. Ford used a 4.88 inch center hole, GM is 4.56 and I believe Dodge is somewhere in between, and they all used 8 on 6.5" bolt pattern. Before you spend $200 make sure they are the correct wheels for your chassis.
As for tires, a tire shop can tell you what current tire size would be equivalent to the 8.75X16.5 tires. An LT225/75R16 should be very close.
The questions you're asking here can be answered at any good tire store.
