Ok I know a picture is worth a thousand words, but my dumb a** didn't take one. I will tomorrow and post it. In the mean time...
1980 IHC chassis with it's lovely split rims and poor condition tires. I'm switching it over to 11R22.5's and hit a roadblock on the front I've never seen and my tire guy hasn't run into it either.
In your mind's eye assemble a front dayton. Rim goes on, you pick up a clamp next. That clamp is flat with a groove cut out where it contacts the rim. Not mine...I have clamps that looks like the letter "L" when viewed from the side.
These fit just dandy with the old rims. New rims protrude outboard a bit farther I guess, and if I install these clamps, they (the clamps) don't sit flush against the spokes.
I've removed and reinstalled the rims about 30 times just because I want to believe I'm doing something wrong, but the things are fully seated on the hub.
I've thought about saying "It's tight so it's fine". I've thought about putting washers on the stud and then the clamo to shim them out. I can't find any different style clamp for the fronts in the books.
Is it fine? Use washers and if so what kind? This bus is due at a show in PA next weekend and I'm really trying to not ruin that. I foresee pitchforks and torches in my future if I do.
