Stock dually wheels are 6" wide. If you measured 7" you measured incorrectly by measuring outside the bead, or your wheels have been widened. Wheel width goes off the measurement between the beads which is 6". No one makes any 10" wide dually wheels although there are some aftermarket 6.5" wide ones. Steel dually wheels can easily be widened though, there is a member on this site that had widened wheels on a dually, 8" I think. I have 35x12.5 tires on my 6" wide dually wheels, they are ballooned slightly, but proper tire inflation reduces tread crowning.

Although note that a 33x12.5 will experience more severe crowning than a 35x12.5 tire due to the shorter sidewall. My smaller 285/75R16 tires appeared to crown worse than my 35x12.5 did on the same set of 6" wide dually wheels. Also you will need 2" spacers minimum between the duals so that your rear tires will not touch and possibly overheat and cause a blowout. I run 2.5" spacers on the rear between my duals.

They are 16.5x8.25". They have 7" of backspacing, which actually makes them great to run on the front as a wider option, while keeping similar to stock track width up front with the dually hubs, but on the rear they will sit far inside the rear dually fenders and possibly cause leaf spring interference unless recentered.

In 97 Ford changed to a metric spread so anything that wont work either. I also have a problem with my calipers being too big for the 16s to fit up front and have some concerns about the rear due to the size of the drum. Mine is a 88 Square C&C so if may have bigger brakes not sure. I actually have a harsh vibration after pulling my flat bad yesterday so I am gonna do some wheel swapping today, I will double check the brake concerns. I use mid 90s Chevy rims on mine had to cut the nub off with a die grinder to make them work.

These wheels are not lug centered, they are hub centric, although the lug "plate" has conical seats for the lugs, it does not center the wheel. Chevy uses a smaller 4.56" hub center on all dually wheels year 2000 and older. In 2001 they went to a larger 4.60" hub center. Dodge wheels used a 4.77" hub center, and I learned the hard way before I researched and learned that this will cause vibrations. I was able to "center" the wheel by hand before torquing the lugs, which reduced any vibrations, but ran that way only temporarily until I got my new wheels. Ford has an even larger center bore, 4.8X" or 4.9X" I do not remember exactly. As mentioned, in 1998 Ford did go to the larger metric bolt pattern and those wheels will not fit at all.

Most all aftermarket aluminum dually wheels are lug centric with a large enough hub bore to fit all three, so the hub size is not a concern on those.

I went from the stock 16.5s on mine to a set of stock Dodge 16s from an 01. This is where I discovered the vibrations caused by the incorrect hub bore. I then picked up two steel GM 4.56" hub bore 16s for rear inners and 4 aluminum aftermarket 16s and have had no issues since.
