I have two stock rear tires off a 2005 blaster, they are in excellent condition. 50 bucks plus shipping and they are yours. I can send a photo if you want, they are hardly used.
I've got two stock rears, no longer on rims, with decent tread, and one stock front tire, not on rim, with almost brand new tread. I don't want much for them, although I am looking for a new stock front rim, and a front stock shock...
