Width of 8 lug wheels on 7K axles?

Anyone know the width of the 8 lug wheels that come on the 7K axles?

I'm looking for the maximum tire size that can fit on the factory wheels.

According to this site which is a major supplier of 5th wheel and TT rims, 6" is the largest they sell. Their 16x6" 8-6.5 rims are rated for 3750lb each for a total of 15,000lbs for four.

You're not going to be able to go much bigger than LT235 85R16 due to axle spacing. At that you've only got about 1.5" between tires.
