anyone running 205/70/15 GYTT?

Getting ready to go darkside. I actually have an 1800 S so my tire is 15' like the 1300's. I'd like to go 205/70/15 GYTT. I want to correct some of speado , and by running 70 profile should gear it up a little too. I'm sealing the spokes with the 3M stuff, It's on order. I found a local bike shop to mount it. My concern is will the 205/70/15 fit under the retro fender W/O mods and not rub rideing 2UP? Combined weight about 400 lbs. Thanks for any info or sugestions. I'm hopeing someone out their is doing this with success. Ride safe. Doug

Welcome here, good move. Enjoy the ride and this great site.
I guess brothers with the same tire will chime in soon.
Did you ccheck the general board as well? There's a topic listed
a couple a days ago about the pressure of that tire.
