The Kenda is a great tire. In my opinion, I don't think its too aggressive for the street. Your options are pretty limited for the rear.
Changing the tire isn't too difficult. I watched many videos on YouTube before I tackled mine. I prefer to use three spoons. Sprinkle a little baby powder into the tire before you put the tube in, that will make sure the tube can slide around inside the tire while you put the tire on the rim.
