how much would 25x12-9 swamplites cost for the back tires?

i need some new tires on my big red 250 (rear)

 

i ordered some BTK or something today. i dont know anything about them but i liked the pattern and they look good. 50 bucks a piece.

 

put my new tires on and theyre pretty freakin awesome. good in the dirt, gravel, mud, and a little rough on roads but still pretty good. i like em. they hold a lot of mud and sling a lot more. im definately gettin some for the back too. theyre btk brand. never heard of em before but id definately recommend them for mud and dirt. with no air in them, theyre nearly as stiff as my old ones were with about 10lbs. plus they look freakin awesome.

heres a link with a pic of em: http://www.powerpartsplus.com/...d-snow-trail-tire.aspx
