How to install new tire on wide rim.

[dfkrug]

I have had luck using small bike tubes to fill the space... Find one that is a good fit,
soap it up, and try blowing up the tire... Once the tire gets to the bead area, it should force out the smaller
bike tube..

That's interesting. I just used some new innertubes to get my tubeless ATV Vampire tires to seat. But I
put the tube inside the wheel and tire with the stem sticking out the stem hole. Pumped it up, popped
the tube, pushed the stem into the wheel, then applied a tubeless stem from the outside.

I did not expect the tube to pop, but it did so with THREE different tubes from the same vendor, new.
Admittedly, I used 3x10 tubes inside a much wider 10" wheel/tire. I expected the tube not to blow
unless I exceeded maybe 4x normal inflated size.

Anyway, I could not do this for highway tires, but inside a tractor or ATV wheel, no problem. Leaving
a deflated tube inside a tubeless tire, that is.

This tire was way beyond mounting with straps, etc, and I already have a way to get air in there pretty
fast.
