I have used my chinese iron apparatus from Harbor Freight to do a few dozen tires (or more). There is a learning curve but it works. With the bubble balancer from the same source, it is possible to produce a pretty good ride.

Installing a tire on a wheel is easy, but tough to describe. The really tough part is breaking the bead down on the tire you want to remove, and then inflating the tire once it's on the rim.
Pay the money.

Without spending some money on the proper tools to do the job, it is nearly impossible, but you are more than welcome to try (just don't hurt yourself because the emergency room isn't cheap these days). Seriously, just pay a tire store to do that task they have equipment you will never have.

I feel your pain about mount and dismount prices. Just remember that even though you somehow may have wrestled an old tire off and a new one on, the issue of balancing will still be there. I just leave it to the pros and go.

Over the years I suppose I've dismounted/mounted about a zillion tires by hand--give or take a few. This is a job best left to a young body--even if you have the proper tools for the job (hand bead breaker and two good tire irons)--but can be done with stuff you might have in the home--as long as some of that approximates tire irons (large hefty screwdrivers, iron pipe with flattened ends, etc). Since you're asking, I'll assume you do not have a hand bead breaker. You'll have to use the weight of the car and a bare rim mounted on one of the front hubs. If you don't care about the tires coming off you can make it a little easier by using a large sharp knife (not the $75 one your wife just bought for cooking) and cut around the side wall on both sides to remove the tread section (remove the valve core first). If you want to save the tires skip the cutting part. Jack up the car enough to slip the wheel lying flat on the ground under the edge of the mounted rim (with the edge as close to the bead as posible). Lower the car to force the bead away from the rim edge. You will have to do this in enough spots that the bead is free from the rim all the way around--do both sides. If you cut the tire it will be easy to slip a bar under the bead section and lever it off the rim (the far side of where you are prying must be in the rim center where the diameter is smaller--if it rides up to the edge the pried section will be difficult to force over the top). Flip the rim and repeat for the other bead. If you are keeping the old tires---place the wheel and tire (with the beads already broken) flat on the floor (a smooth floor works best). While standing on one side of the tire sidewall to force the bead down, place one of the bars under the bead on the opposite you and pry it over the rim. Leave that one in place while you put a second bar under the bead a few inches from the first--pry that edge over--now go a bit further around and repeat (all the while standing on the sidewall). The whole assembly--you included -- will slide on the floor a bit. When one side (steel rims and most alloys come off the front side--but NOT Turbo rims--the tire has to be removed from the back side on those) is completely above the the rim place the tire in an upright position. Position the rim so the bead that is still within the rim width is on the side you are removing from. Place a stout bar under the bead angled from the rim side towards the outside, catching the outer edge of the rim. Pry the bar over the top of the tire and use a heavy hammer (I use a rubber mallet made for the job) and beat the bead down so more and more of the remaining rim is exposed--eventually when enough of the rim is released the wheel will fall away from the tire. If all of this explanation doesn't make you too tired (pun intended) to proceed I'll make another post with how to get the new tire on. -- Dave

Harbor freight sells a non air powered DIY tire changing machine for around $40.00 I think you have to bolt it to the floor and be mighty ambitious.
