PROS:
The narrow width of the tire makes the contact pressure on these way up there. Allowing what seems like an uncanny amount of traction in situations where the pizza cutters seem to outgrip and climb where others slip and struggle. I owned a set myself and always like them, a couple buddies have them currently and love them also. Thinner tread width keeps rubbing to a minimum. As far as I know every tire available in this size is a load range E.
CONS:
As far as I know every tire available in this size is a load range E. They definitely take some time to break in, and they do. The narrow overall width leaves pretty much zero protection for your rims from rocks (curbs in your case

). The tire selection in the size is pretty slim, and not the cheapest at that.
I like them, but wouldnt run them based on the reasons above.
