Sure it's possible to change a tire but if your like me you'll find it's easier to do half of the job and let the people who have the right equipment do the rest of it.
What's half the job?
Removing the wheel and taking it to the motorcycle shop.
If it's the front wheel the job is pretty easy if you have the right size wrenches and a scissor jack from your car.
Loosen the pinch bolts and the large nut on the front axle. Place the jack under the front engine mount and raise the bike so that the front tire is just clearing the pavement or floor. Knock out the axle keeping track of where the spacers are and being careful with the speedometer drive unit.
The rear tire is a little more work but there are some posts here that can help you thru it.
Getting back to doing the whole thing by yourself you'll find the tire changing tools supplied with the bike are pretty flimsy and they can be bent when your prying the tire off of the rim. Also, they supply two of them but you really need three.
The first time I changed a tire was on my Honda 400F. Getting the wheel off was easy.
Getting the tire off was a PITA but doable. Getting the new tire on however was a monumental task.
I tried dishwashing soap in water to lube the tire bead but even with this and all of my pry bars it took the better part of the afternoon. I was lucky because I didn't pinch the inner tube but doing that is easy to do and you won't know its damaged until you try to inflate the tire. Then, it's back to square one.
