What size tires on stock rims?

[Prazak250EX]

I'm lookin to get some new tires for the 250. I wanna know what size Shredders'll fit on the rear stocker rims. I'd figure it out, but I'm too lazy. Also how the hell would I get the tires off the rims w/o a beadbreaker. I'm tight as hell on money, and don't really want to take anything to a shop cuz they charge an arm and a leg

there is a big range of tire sizes that will fit a stock rim. it all depends on what type of riding u do. as for gettin them off the rim..run the tire over witha truck.
