Question
I want to replace the oem wheels... the front axle is 4000 lbs. + the rear is 4150 lbs... I can't seem to find out the load rating on the oem wheels... the replacements I am looking at are rated at 2200 lbs each... they would seem to be adequate but I am not sure on the std. between axle and wheel can you advise

Answer
Sounds reasonable.  Each wheel supports half the axle load.  Unless you are doing heavy duty hauling, or driving like a race driver offroad, there isn't a good reason to go to a higher rating wheel.  Four of the wheels you mentioned are rated for a vehicle grossing about 8000lbs.
If you really need more capacity, go to an offroad 4wd website and start looking, or try US Wheel.
