Having making myself ill looking at my truck with the weenie tires on it. (31's)
I took it apon myself to see the base mechanics, to learn what not to do with split rims. It all boils down to making sure that the split ring is properly seated on the rim and that the tire inflated evenly on the rim.
They insisted that the use of a safety cage is a must. or in the field they will thread a chain through the holes on the rim and arount the tire and split rim just incase it pops. Also they use a clip on chuck and a remote valve that is a good 10 feet away to inflate. As the most dangerous part is the inflating and inspecting to see if the bead is properly seated.

Anyway this weekend I changed all 4 weenie tires for the stock NDT's (ya ya I know but I wanted the stock look since she is now a Sunday driver )

Ah back to the story... I took me 6 hrs to change the 4 tires this included building a remote air filler, cleaning and painting the rims. ( now I can do it in about 30-45min/tire) The hardest part was breaking the bead of the last tire.
Couldn't get off after hours of prying and pounding, tried driving over it,
Driving with it deflated and doing donuts, sitting the hi-lift in it and lifting up the front of the truck. nothing would work. so out came the sawzall
5 minutes of cutting and it was off. Even managed not to cut the tube or liner.

All in all, I am glad I was able to do it myself. and it was a positive experiance (except for that last fricken tire!)

If you do try this at home just do it CAREFULLY!
These things can be deadly
