2ct's are great for the streets, you'll get plenty of miles out of them! I had a set awhile ago and for the price point, grip, and wear, they're outstanding tires!
I'm sure our Vendors could get you deals on tires, but I doubt anything that would beat those prices from amazon. I'd look into where they're coming from, what company, and do a little research before I purchased... If you feel there's a catch, maybe there is... Look into it...
