But do check the clearance between the tire and the fork unicrown. From the illustration in rei.com, it looks like you might be able to go 2 mm fatter.
As you can see, there's no room for MTB tire, unless you want to replace your wheels and fork.
And to get better traction and ride, your tires will have a more purposeful tread pattern and a more supple casing, so be prepared to spend more.
