i think the Tomahawks are the ones that are re-treads....
they come in colors too!
i would suggest save money elsewhere (take your lunch to work, switch from cable to hulu, cancel your web connection and get on a neighbor's unsecured wireless
) and spend the money on good tires. they are a safety item.
here's some other ideas-
i think cycle gear has a sale coming up with a tire combo really cheap
dunlop has a new bargain sport tire- 616, and their roadsmart tires have been getting good reviews
i just got some Avon Storms on my bike, and they have nice feel and will last longer than supersport tires
