Hi Terry
You raise a good point, I'd like to offer a little clarification I have 16" rims on my HUP which are 6 lug rims these take the standard US military tires without difficulty, no trimming. I also own a C60L with 16" rims which are 8 lug rims which will not take the tires that fit on the HUP rims. To get the US tires to fit the 8 lug rims it requires trimming a small amount of rubber (no cording or fabric) off the outside edge of the bead (the first bit to hit the rim when mounting). Your point about not cutting the metal or trimming the rubber is of course good advice particularly if it can not be done uniformly.
To trim the 900x16 US NDs on my 16 inch 8 lug rims, I mounted the tires on a large Lazy-Susan so that they could be rotated while a air grinder with a fine sanding disk can be used to reshape the tires rim lip so that it would slip on to the rim. In my case only a very small amount of rubber had to be removed to get all four tires to mount correctly.
I have also noted that there is often a mounting problem if the tires have been sitting in a stack and the two beads are squeezed together which changes the angle of the bead as it first contacts the rim. Spreading the beads rolls them apart which changes the angle at which they first engage the rim. In attached photo you can see how I mounted brand new 11:00x20s on the C60 twenty inch rims this particular tire had been at the bottom of the stack and would not go on easily, with tube slightly inflated and lowering the tire square to the rim it went on with out difficulty.
Now just to add to the confusion the 20" 8 lug rims take the US tires with no trimming problems.
