I've been running Vittoria Randonneur tires on my credit card touring bicycle, and like others mention above they are no longer available. An alternative I'm trying are Performance's Gotham St tires on my commuter bike - they are heavy, but puncture resistant and inexpensive. So far no problems. I might stop by their local store and pick one up to use on a short tour I've got planned over Thanksgiving; if that works I might start using them on both wheels. 700 x 32 tires
Continental City Tires - had a pair on my commuter and it wasn't the tread that wore out, but the sidewalls. They split and cracked something bad and I had to trash them. Never again.
