Big horn 2.0

I got back yesterday from a week long trail riding vacation up in UP Michigan. It was fun by the way. But I ended up getting flat one of the days. We plugged it and slimed it, its still leaking... So my questions are... Does anyone have a rear 27x11x14 big horn 2.0 for sale or know where to get one? Any ideas know how much they are? I'd also like to get a front tire and rim to use as a spare for next year. (27x9x14 big horn 2.0)

Thanks!
