...where are your trips planned ? In California, during the dry season, touring for a week or two on a bike without fenders is easily done.
I honestly cannot tell much from your pictures, but from those, it looks like those fenders are too narrow for the tires you have on there.

But I wouldn't go buying new tires unless and until you have a better idea of where the fenders will end up, mounted.

As said above by someone else, all ender mounting on bikes is a custom job. On some cycles, I've had to drill out the rivets on Blumels to remove and/or modify the mounting bracket in front.
