ive mounted my own tires many times

all you need is 2 flat bars and a can of ether to pop the tire on the beads

once you get the tire over the rim,,,spray some ether in side the tire,and dip the end of a broom handle in some gas,light it and just hold it next to the tire,,,,poof the tire is seated,,,but you need to have a compressor ready,because when the gas's inside the tire cool(pretty fast),the pressure rapidly goes down,and the tire will unseat

then you need to over inflate the tire,until it seats over the second bead,and then deflate until your desired pressure

of course this is the HillBilly way,and not recomended for the non-HillBilly,,,,red necks may be able to perform this task too,,,,lol
