Trick to make tire installation easy... While spooning tire on, be sure that the opposite side of the tire is in the Drop center (The deepest part) of the rim. Start installing the tire from the side of the rim closest to the drop center. This way you will not be stretching the bead of the tire enough to cause damage. You should be able to push the first bead over the rim by hand with no tools by pushing alternately on the left then the right working your way around as long as you lubed it enough. If not you will only have to use a tool for the last 2 inches. As far as lube goes, A good thick dawn/water mixture will work. Before you set teh bead simply wipe the inside of the rim clean and dry. This will prevent corrosion and insure a good balance. Most tire lubricants are nothing more than vegetable based soaps that look like grease. In my other life, I changed everything from golf cart tires up to the BIG tires on articulating Farm tractors and Loader tires. All easily done with hand tools and lubrication ( OK, the loader tires I cheated and used a power pack and a crane
) It's not a hard thing to do and DEFINATELY NOT worth paying $30 wheel like they get around here!
BT I like to work on my own stuff as much as possible also. I may not know everything a "certified" mechanic knows but I am confident what I do is done correctly and all the little details were attended to!
