>>1046700Travel to Utah, California, Arizona, Texas, Nevada, even some places in Colorado, and Nebraska backroads are awfully shit too. Pick any backroad 4wd route that follows washes or is unmaintained. Your 2.2" tires will sink and you'll be in for a suffering. A decent fat bike can be less than 30 lbs. And once you're touring on a rough road 200 km from nowhere, the efficiency argument is out the window, because you'll be pushing and I'll still be biking. I just did a 14 day trip within Death Valley and I wouldn't have gone there with any less than 4.8" tires.
