I have a roller brake on my Nexus hub and it does
not have the stopping power of a coaster brake -- it works about like a caliper brake that barely touches the rim with the lever all the way at the handle bars. I would recommend the appropriate caliper brakes for your ride, front and rear.
Edit: oh, yeah really fat tires. That complicates things. Do you have a frame? That is cantilever territory.
