These tires are great, I swapped them on all 4 of my fat tire bikes as all we do is street/bike path riding.Yeah I think you need road tires.
I will note however that the prices swing wildly on these. I bought 4-sets (8 tires) at $44 for each tire back in Feb. went to get another set a few weeks ago for my tandem, not that the original tires are nearly done and lowest I could find them was $98 EACH.
FWIW. with these Origin8 tires I have over 4,000 miles on one set of them on one bike and they still look great, not a whole lot of wear. the original knobby Kenda tires that came with the bike didn't even last 2,000 miles.
the Kenda Juggernaut tires on my tandem have 1,900 miles on them and are nearly smooth, though to be fair they are taking double the weight since it is a 2-up bike.
