Mounting a car tire
Just put the tire on the ground and then next the rim on top (rotor facing down) make sure you have some cushion under it like a moving blanket to prevent scraping
now jump up and down on the rim until it is in, flip and repeat process to seat the other side, but jump on the tire this time, be carefull since the rim is now closer to the ground
works like a charm
disclaimer: I will not pay for any damages occurring from this process
oops forgot to add soapy water to help slide it on and a tie down strap to help with the sealing when airing it up
