    Im doing something similar to this but not sure if it will work for you as the tire is at an angle...
    Basically I have created a seperate image with just the wheel and layered it in Interface Builder on top of the background in the exact spot it would have been in the original picture.

    Code:
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:WHEEL_DURATION_SECONDS];
    	
    // rotate the wheel
    CGAffineTransform transform = wheelView.transform;
    transform = CGAffineTransformRotate(transform, (M_PI));
    wheelView.transform = transform;
    	
    [UIView commitAnimations];
