I've changed about 5 tires on my motorcycles now and the hardest part is getting the rim into the tire, even with a second set of hands. I change it the way it is demonstrated in the transworld motorcross video tutorial. A tire spreader would make the job a lot easier, either a home made one or manufactured. I don't have an easy way to heat the tire so that is not an option. I found this It's $75 and looks like you have to manually spread the tire which is ok but I can't tell if there is some way to hold it in the spread position, it doesn't give many details with the product information. If you use a spreader let me know how it works for you.
