In your case you may want to try airless. They will definitely slow one down, but what I liked was the harder work it was to traverse the same distance and terrain as with pneumatic. Never used them for commuting, though. Dont even know if they're still being made. My use of them dates back to 2007-2009.
Well, they're still being made apparently:
