We did trim the bead with an angle grinder on the michelin tires in order to get them seated on the rim. However I donnot think that we really had to. We have taken a tire off since as we had a bad tube and it was no problem. I think one of the big things to look at is if the inside of the rim has had any rusting and flaking as some of ours had. After cleaning up and sandblasting you have actually removed some of the rim material which will make it easier getting the tires on.
Phil is correct in that the HU rims are much lighter in construction that 15cwt rims and the tires will go on and off with ease. Our HUP rims where rusted badly and after cleaning and sanblasting, the tires we had pretty much fell onto the rims.
I guess the biggest thing would be to look at your rims and the type of tires you are mounting in order to make any desicions on trimming. We asked our local tire place about trimming and/or machining the rims and he did not recommend doing either.
