Low Lift, Big Tires on a fzj 80 series is equals 2 to 3" of up-travel. (38"s, 39"s, 40"s)

A few years back I played a game to see just how low I could go with 37s on a 80 series. I learned a lot & will share it with you today. 37s will fit with 1" suspension & 1" body lift with 1" front/1.5" rear lowered bump stops. 
(If you have a 2" suspension lift then run 2"front/2.5" rear bump stops). 

When I fitted 38s on a 2" suspension/1"body lift, I used 1" front/2.5" rear bump stops after moving the axle forward 1". 

Just to note: the starting point...stock front up travel including compression is 3" the rear is 4.5".
Front bump stop gap is 50mm/2" for fzj80 series.
Rear bumps are hard... maybe .5" of crush if hit hard enough. 
Fronts crush 1.5 if jumping.
So under normal conditions if you add the 2" of up-travel plus 1" of crush the normal 80 series has 3" of up-travel in the front.

Now you know the spec, here are some 80s I found on the WWW.
