hahaha, i just saw watched a old (92 ish) drift tengoku where this guy took off and replaced his own tires using just a jack stand and 2 tire spoons. he started when the sun was out, and ended when it was dark.
if you really need me to explain it i can, but it does look like a pita. for all the hassle i would recommend taking them to a shop, expecially since these are for driving tires. if you were replacing drifting tires that you were gonna burn up in a night, things would be different. good luck!
