The problem with rotating tires on a bicycle is the profile thats worn into the tire and the consquences this has on handling. A tire that's only used on the front will maintain a round profile and it will provide safe steering. A rear tire will wear flat in the middle and if this tire is transfered to the front its effect on handling will be horendous. It is OK though to transfer front tires to the back and get a new front tire.

Ohh and regarding Veredestein Fortezza tires I use and reccomend the Fortezza Road/Race tires but I've read a lot of negative opinion of the Fortezza SE model.
