Don't mess with the wheel! On mine, the fender nut cages have been removed and bolts were replaced by carriage bolts. My tire has never rubbed anywhere. There are some excellent "how to" info pages in the "shop talk / Carl Kulow maintenance pages" as well as other places.
Here is the tire with about 6000 miles. Appologies for the dirt, pic taken after about 45 miles in rain and wet roads at the end of a long day riding the mountains.


Part of the trick is getting all the work done right. You can't take it to a shop and get this all done for you.
I am not super mechanic but I did my own work on the bike in the garage.
My local tire shop mounted the tire but could not balance it.
Local bike shop would not work with a CT but did balance it for me.
Wanted $20, under the table.

(They are not on my X-mas list)
Maybe that was reasonable but I felt over-charged.
While I was in there I replaced all the seals, o-rings, etc. Also replaced the header gaskets and a few of the header bolts and nuts that were stripped out by previous owners / shops.
IMHO this is mostly about saving money (miles per tire) and the looks of the tire. I do like the ride with a CT and I too selected the GATT based on its popularity and the predictable good results based on the group's experience. I do like the look of the GATT. That being said, there are some other tires out there that look very cool. I will look for "Max Gnarly" next time around. I suggest looking around a bit for the tread design that you like best.
Also keep in mind the Height / Circumference of the tire and how it affects the engine rpm's.
The 205/60 is the closest to the stock tire size and has little impact on the rpms at speed.
