Flat tire on 2001 BMW 330Ci

I have a flat tire on the back right and I can not get my wheel to come off. I have tried putting the lug nut back on and kicking the tire but I can still not get it to break loose. What can I do to break it loose.

With all of the lug nuts OFF, kick the very bottom of the tire. BE CAREFUL!
Kicking the bottom of the tire should pop the tire off. If not, try using more leverage to pry it off.
