Go BFGs
Even 2nd hand they last well and give a really good ride on road even the MUDS.
If you get 12.50s and put em on an 8" rim you can safely air down to 10 psi without losing a bead. So great on rocks.
If you get mud in em and they leak. easy enough to use Hi lift to burst bead and remove mud then air up......
Up till I went 39.5...I used 33s and 35s in a BFG mud flavour for 10 years........ as i said great on road and great offroad............. never be good as a bogger in the mud but you don't to run them on road
