It kinda depends on what you want to do with them...
Just use a larger Tire on your same Rim, or
are you going to replace the Rims too ?
Street/AW/Mud-Snow/Climb, it makes a difference !

Increasing Tire Size
Ok, and from your post, you already know you can get TOO big, and that would cause scrubbing.
As a start, you can go to...
http://www.tirerack.com/tires/dg/MenuServlet?search=tdg
which is a "Decision Guide". Fill out the cells, and it will list several M/S 16" that you can select from.
Be sure to note what your standard "width and diameter" is on your present Tires, then, the width and diameter of the larger ones. You then can "estimate" what clearance you have to deal with, and select a size accordingly.
Understand, that when you do this, that it will make your Speedometer read slow, and there will be a moderate loss of the "firm/control" feel, when you increase the proportion/width. Keep in mind, that the lower pressure you customarily run in your tires, the more "spongy" they will feel, and that does effect the control you have of your Vehicle.
Just as a tip, I've always run a new set of Tires at Maximum Cold Inflation Pressure for about 100 miles, just to get them seated and settled on the rims. Then, you'll have to reduce the cold inflation pressure to below recommended, to get the Tread to run flat on the road. That will assist in getting even tread wear over the long run. I wish I could give you a solid number on that, but it depends on the Axle Loads you customarily have.
You may already know this as well, but, when installing new Tires on any vehicle with ABS, AWD or 4WD all the tires MUST be the same size.
Now, it's possible that someone will come forward, who has a similar vehicle as yours, and, give a Size which worked for them. That would be greatly appreciated, but, there can be differences in the Build from one Vehicle to another, and a close visual inspection and evaluation of the clearances, is still necessary.
Just for reference, here are a couple Post which may be of interest to you...

Increasing Tire Size, Turning Stops/Limiters
TMan,
Sorry, but, there's no way I can actually say.
However, that's not that big of an increase, and it's very likely that they will do just fine. Sorry I can't be absolute about it.
Now, IF there is a "little" scrubbing, you can make minor adjustment to your "stops", and limit the travel on your wheels. That will increase your turning circle a little, but can be very easily done with a little Spot Weld.
