Tires + Beadlocks

I just purchased a pair of 18x11x8 Turf Tamers. I am in the market for a pair of champion rear dual beadlock rims. What size rims would fit these tires correctly?

Thanx

8x8 are what my champion beadlocks are, and i'm running the same tires you are on them. check out www.championwheel.com for a list of the sizes made. i think 8x8 are your only choice in champions.
