Yo! I've got the same lift on mine, and i've just fitted some 32x11.5 tyres on it! The biggest i could possibly squeeze in!

I had to trim the back of the front fenders a wee bit, but it still looks dam neat. They catch the chassis/frame on full lock, so i've just extended my steering lock bolts (on the steering bar beneath the steering box) to prevent this from happening. Just means my turning circle isnt amazing! lol
I'd say go for the 11.50" wide ones, IF your rims can fit them! I squeezed mine onto 7" alloy rims, BFGoodrich recommend at least 8" for this tyre

Some more details on mine here -
