Visually your tire doesn't look unreasonable. If the wear was fine on your previous set of tires and the car drives straight with no pulling, I'd assume that it is alright. If you really want to know what it is you'll need to measure it with alignment equipment. Once you've done that it's really a question of understanding what you want the rear camber to be. That's a more complex question but if you do a search through this BBS on "alignment", "camber" or "do it yourself alignment" you'll probably learn more then you want to.
