This week, I had my first experience at setting a gleaner drive tire 18.4-26 bead back onto its rim, while tire was mounted on combine, & using 20% ether for a somewhat controlled explosion?  Some rust/dirt had worked itself into/around inner lip of rim's bead. I watched a few youtube videos before I attempted it. I also bought a $100 harbor freight bead breaker to remove tire from rim, which worked very well.  Did both sides of tire. First side broke loose bead, cleaned up rim using angled grinder 4" wire cup. Placed two 6 inch long 2x6 scraps between tire & rim to allow access for wire cup. Used a narrow 1" wire brush to rough up/clean tire bead area. Applied tire bead sealant to both surfaces, and then using a ratch-strap, started that side's tire back onto rim, but did not fully seat it. Then removed wheel(tire/rim) from combine, reversed its mounting, and repeated same procedure on other side. Then used ether to expand tire outward onto rim. Took me a few tries to get it right. Here's what I figured out?

1. Center loose side of tire's gap to rim bead as best as possible. Leave at least a crack(1/8"?) near upper circumference. Any excess gap near bottom.

2. Have air compressor pumped up & air line close by for quick airing after beading.

3. Moderately spray ether from 4oclock to 8oclock around tire's bead seam(about 4-6 seconds continuous spray time?). 

4. Include an "ignition puddle/patch" of either away from tire's bead, towards an outer area of tire sidewall at an upwind side of tire. In my case ~ 8oclock. Wind blowing towards 4oclock. Wind helped blow flames from puddle to bead area & allowed me a few seconds to get back.

5. Use a butane torch to quickly ignite ether at an arms length & step back.

6. After explosion, quickly air up tire.

Anyone else have any tips to add? No, I don't own a cheeta or air blast tank.
