The difference is so slight that it wouldn't be noticeable unless your doing well over 100 mph. I believe both can be reprogrammed at dealer, I know a tuner usually can be modded to take the change into account but then you need to keep it attached all the time. I was going to suggest tirerack after reading your original post but see someone knew about the place. Discount tire direct usually has some very good pricing. If you pick tires and rims they mount and balance and ship free, I bought rims and tires from them when I had my old truck.
The only error in your post is that you do not need to keep a tuner attached all the time in order to account for tire diameter. The change is downloaded into the computer. Same as any tune you may install.
