Thanks for the link!
I know my current tires are way overkill for my use. I am more than likely going to replace them. There are so many different options out there, though. lol
I was thinking something smoother down the middle with some grip on the sides might work. Something like the Specialized Crossroads. The link above doesn't like that type much though. I am a little afraid to go with something like the Specialized Nimbus which doesn't have much tread at all because I am not sure how it would handle on the limestone and packed dirt. I have a No Fall rule I like to obey.
