Per the Tire and Rim Assn. (TRA), all tires in size 235/85R16 require a rim between 6.00" and 7.00" inches wide. The Denmans wouldn't be any different. I suspect Denman picked the 6.5" wide rims to calculate their specs, but it's okay to mount those tires on wheels that are 6", 6.5" or 7" wide. Of course, if you use a different width wheel than the one they used to calculate the published specs, then the tires mounted on those different width wheels will have slightly different specs for things like C.S. and O.D. But listing the specs for all possible different wheel widths would clutter up the table too much.
The main concern for trailer wheels is max inflation pressure they are designed for. Those Denman tires can hold up to 80 PSI, but some trailer wheels are designed for a max of 65 PSI or even 50 PSI. So look at the specs for your wheels (probably stamped on the inside of the wheel so you have to dismount a tire to see the specs). Your wheels are probably fine for 80 PSI, but you'd need new wheels if you decided to upgrade to load range G tires that can have up to 110 PSI.
